More on the inner-staysail bulkhead

In this pic I have painted the bulkhead but have not attached the fuzzy hull liner, the bow-locker door, or the chain-locker doors.   The hull liner is the roll wrapped in cardboard paper lying on the bunktop.

I am not going to paint the faux-teak bow-locker bulkhead, just for old-times' sake, to show the original fabric of the boat as-built.  The small holes in the stem are awaiting the fitting of the stem fitting (see here).

In this pic also can be seen my method for securing the forward hatch: small cord tied to eyestraps on the hatch, the same as my dad did on our 31' plywood yawl in 1962.


The fiddles on the hull shelves, port and starboard, are made high enough to make bins.  These will hold sailbags (it's a small boat!) and other stuff the way the old ones (about 2" high) never would have done.  Above, as though a facia covering the toerail bolts, will go a similar board to hold hooks from which sail bags, fenders, dock lines and other things can be hung.  As such, this space becomes a bona-fide forepeak, nothing like what's found on even much, much larger yachts.

The varnished board down the center of the underside of the deck is, in this pic, just sort of stuck there.  It is meant to catch the bolts and backing plates of the foredeck cleat, the inner-forestay's attaching plate, and the anchor winch.

I am not happy about the gaps along the top of the chain-locker bulkheads (to port and starboard here) against the underside of the deck but will leave the fitting of some varnished trim for some later date!

Inner-forestay support

This pertains to the pole-lift/inner staysail idea I've had for a while.  The blog post is here: http://dianaofburlington.blogspot.com/2012/08/internal-pole-lift.html

In fitting an inner forestay, even if it's a detachable one, the foredeck needs to be reinforced.  Though I've filled all the rotten core adequately, the deck alone won't support something that amounts to a chainplate and may be called upon, in a catastrophe, to support the rig as the only surviving headstay.  So I decided upon a "horse", a structure going athwartships at this point.  Here is my original drawing (on the piece of plywood I would use for the crossmember/deck beam).


Below is shown the initial structure, two short little bulkheads in the forepeak, aligned with a couple of sticks.  The stick under the starboard-side shelf is propping up the shelf from its as-built position, as it was both angled downwards inboard and also too low.  The cleat on the forward bulkhead (what used to be the rode locker)  is aligning the two shelves more or less evenly; though the starboard-side one, once leveled, is too high by 1/4".  Such is the nature of budget-minded mass-produced yachts of the 1970s.


Of course these pieces narrowed the space considerably.  I had trouble wedging my out-of-shape self forward of this to disconnect the running-light wiring (along the port side) which kept getting in the way; so I decided to cut out the bulkheads a little.

I am always wary of amorphous shapes like this (such as on the back of the Hyundai Sante Fe SUV, which is downright hideous) so I just used a 4" sanding block to scribe a line parallel to the hull and deck all round.  This picture shows the cutout with the crossmember in place.  The bulkheads are 3/8" and the crossmember is 1/2".  I use mainly good-quality cabinet-grade plywood, well-saturated in epoxy and sealed in epoxy paint (these will be done in Easypoxy).  The void to port is for the wiring, which here I have tucked back out of the way.


Pretty cool how the bow-locker door hinges open and fits into the curve of this new bulkhead; huh?  (Should I say I planned it this way?)

(And, yes; this is where the microwave goes.  I've written on this before.)

On most budget-minded production boats, the V-berth shelf is meant mainly to stiffen the hull above the bunktop, as this tends to be the longest and highest section of otherwise-unsupported fiberglass hull on most boats.  It's not there to be useful; and most of the time the fiddles on the shelf are so miniscule as to be only for show.  Determined to have a proper forepeak, I made these high enough (6" inside) to contain plenty of gnarly gear that will accummulate here, like fenders, mooring lines, a mooring pennant, spare tackle, and probably even a couple of sailbags (Diana's main and jib already share a bag that would fit in here as it is).  The fiddles are made of 1/4" plywood, just decent cabinet-grade lauan that I had got to finish some Barbie dollhouses for my kids.  I cut them down forward of the new bulkheads to allow the little door (the only cabinet door with hinges in the whole boat) to open fully.


Above is to go a mahogany plank, about 4" wide and 1/2" thick, to serve as a backing plate for the deck winch (which serves the anchor rode), the mooring cleat, and the inner-forestay attachment fitting, as well as the aesthetic purpose of representing the centerline.  Originally I made this for the full length of the space; but I will cut it and fit two pieces to the fore and aft of this crossmember.  It occurs to me to have some really nice bright white LED floodlights under the deck, forward of this, to illumine the whole compartment.

Along the deck, against the hull, kind of like a facia meant to hide the toerail bolts, I will fit a wooden cleat between the new bulkheads and the (new) chain-locker bulkheads, on which can be mounted hooks and straps on which to hang line and sailbags and other stuff.

These pics were taken a few days ago.  As of today (Saturday, 24 May) I have applied a fillet of 5200 along the hull and, using WEST epoxy, 'glassed the bulkheads and crossmember into place.  When this is kicked-off I'll be painting this with semi-gloss Easypoxy.The original faux-teak forward bulkhead will be left as original; though when I replace the door I'll be replacing the tired old brass-plated-steel offset hinges with some in SS or chrome.  My daughter Rachel hand-painted ship's wheels and anchors onto some wooden knobs for my mother's kitchen cabinets recently; there is one left over and I may use it on this door.

Stay tuned for the pics of after I install the rode-locker bulkheads and trim up here.  I've mocked it up a few times and it's going to look really cool.

It's been a long, cold, lonely winter.

The winter of 2013-2014 has been harsh to New Jersey. Most people of a certain generation are hard-pressed to recall more nasty weather. It hasn't been the frequency of snow, nor the intensity, but something like a combination of the two. We had two major power outages in the region and the township plowed exactly once in six major snowfalls. Plus I was commuting 52 miles each way to work at a marina on the Shore and lost plenty of time and income due to weather. Nearly nothing got done on Diana between early December and about five weeks ago.


Here are some updates, in no particular order.

Foredeck hatch


I finally got the foredeck hatch done (or done enough) and set it on the boat the other day, just before one of the rainfalls we've been having on and off all week.

The poor contraption has been kicking about for about three years. Here it is getting a coat of varnish after I plugged the screw holes in the two sticks on top. (They are aligned over the two ribs which stiffen the frame and the Plexiglas.) I had to take the mahogany down to about 80 grit in some places. Right now it has about three coats of Captain's Varnish on top and about five or six on the sides (on the frame).

Here it is (below) after I set it onto the hatch base. The construction of this is exactly as we do on the Cherubini 44-- it is essentially two boxes, a frame and a coaming, made separately. When you have fit the frame box to the deck, you slice off the top portion (in this case 2-1/4") with the table saw, rolling the thing over the blade to cut the four sides. This ensures you have a mated base and hatch. Once the base is installed on the deck, you install the coaming inside it. I set the front of the coaming back about 1/16", using some lauan doorskin plywood, to allow the bottom inside edge of the hatch to clear the coaming as it hinges open. I also slightly tapered the outside faces of the coaming, above the base, to provide clearance. Actually there is a bit more clearance than is necessary or desirable; but it's not bad.


As viewed in profile, the hatch base is probably too high. During my usual intellectual communing with my dad, I apologized to him for it. He would have had it a whole inch lower to the deck.


At 24 x 26 inches, this opening is sort of a forward "command center" from which one can lower or raise the anchor, navigate and deploy or stuff headsails. The dimensions also allow for the hatch cover to be unpinned from its hinges and lowered through the opening to stow it below-- a consideration I considered paramount and one which led me to increase the former molded coaming's opening (in essence I sliced out the whole molded coaming entirely).

Today I got to enjoy this in a light drizzle, which was actually pleasant. The translucent white Plexiglas allows majestic light below and even when only partially open allows adequate ventilation.

Electrical panel


I have since added the rest of the trim to this; this is a pic from a few days ago. Today I concentrated on wiring the guts of this panel. As you can see the electrical space is located along the hull shelf above the quarter berth, using the original faux-teak-plywood shelf and just adding a front and top.


 The small panel to the left (aft) is the 115VAC panel.  Below the double breaker is the slot for the battery-charger's breaker.

The two main 12VDC panels are for the lights and other circuits.  There is also the bilge-pump switch, voltmeter, fuel-level gauge and a 12VDC outlet.  The voltmeter reports the status of the three batteries (a two-battery house bank and one starting battery) by way of three push-button momentary switches.  There is a switch to turn on or off the fuel gauge as well (switch is not in this pic; it was installed today).

The two rotary switches forward of the double panels are selectors; one is on the running-lights circuit to choose between the masthead tricolor and the pulpit-mounted lights and the other one is on the cabin-lights circuit to choose between the white and red lamps.  In this way no one can activate a white light below when the boat is being navigated at night.  The two rotary switches are aligned with their respective master switches in the panel to their left, as though pointing towards their home circuits when they are in the "normal" positions.

Bookcase


I installed this a while ago but never got a decent pic of it. (This isn't really a decent pic either.) The bookcase is an alcove built into the head (aft end) of the starboard-side settee, under the galley counter. It is scaled for paperbacks of 6 x 9 inches and accommodates things like the Eldridge's, novels and certain tools manuals. There is a blue LED lamp inside, activated by a switch above the galley. The little plywood end (to the left in this pic) opens to a compartment outboard of the books where I can "hide" (stash) CDs and DVDs that are not immediately needed or already loaded into the computer or iPod.

 

Head compartment


Almost all the trim in the head has been installed. As built, the Hunter 25 did not come with a basin in the head; there was just an open bin above the footwell of the berth on each side. Diana's PO took out the floor of the starboard-side one and added a hanging bar so that coats on hangers draped into the footwell of the bunk. I restored a floor here and made two "duffel-bag lockers" for guests' gear. This pic shows the top of those lockers (without their access panels installed) and the trim.


To port I installed a proper basin for foot-pump pressure water.  The portion of the countertop aft of it lifts up to the old bin's original floor, providing a space about 4" deep for "lady products" (for my daughters) and other stuff that isn't needed every day.


The old-style black-based Whale faucet is mounted in a 7/8"-ID stainless-steel flat washer serving as a trim ring.  The other washer lying on the countertop was meant for the bottom but I haven't been able to get my (arthritic) fingers up into the access hole underneath to install it.  The aluminum tube of the faucet is a little tatty and I may opt to replace it later; so this is a job that will remain "temporary" "for now".

The lockers outboard of the sink are for towels (aft) and toiletries (forward). Right now they hold everything I took out of the galley lockers in order to finish those now.

In this picture I still owed the fiddle of the lift-up some varnish; but as of this writing it's been done.

The black conduit tubing will get tidied up. But due to the crossmember (on which the junction box for the spar wiring is mounted), the wire loom can't drop straight along the bulkhead; so it is led about an inch away along the cabin side and through a hole in the top of the locker. I did not make a fiddle here; the trim is just a common corner bead. It's too narrow a space to put anything on it anyway.


My mother, the accomplished seamstress, is making the curtains for these windows. They will span the full width of the space so that, when closed, they will be proper drapery that regularizes the oblong shape of the deadlights. The same will go for the main saloon as well.

I still have not connected the fresh-water lines to this sink. The holdup is solving the water-filter question. It's looking like I will install two undersink cannister types, one here and one in the galley. RVers tend to use a "pre-tank" filter, hooked up to the garden hose as they fill the tanks; but this requires that the water in the tanks is presumed good. Most of the bad-tasting water I've encountered has gone bad in the tanks. I'd rather apply the charcoal and coconut-shell filtration at the tap(s), so I'm looking into Purete and Whirlpool compact filters. The one I've got in mind for the head sink is meant for icemakers and its connections are for 1/4" tubing. I may be able to do without the small-ID "quick connectors" and adapt it to 3/8" supply hose for the head sink. The galley can get a 3/8" one adapted to 1/2" supply hose.

What it's supposed to look like....

These illustrations are from an early brochure done by Hunter marketing based on my dad's 1972 drawings of the Mk-1 Hunter 25.


My dad's idea was to have windows like an airplane, aluminum frames having the right shape and then just installed in the cabinsides. John Luhrs later thought it was best to use the same commercially-available portlights all other boatbuilders used; and the design went downhill from there.


It was my idea to extend the settee berths under the bulkhead-- I had seen it on some more-obscure boat before. By doing this we got a 5-berth 25-footer that still has a decent cockpit.

The wrap-around coaming was my dad's idea but we all (Bob Seidelmann, my brother, Warren Luhrs, my dad and I) contributed to it. It is good-looking, if awkward functionally, except for at the back where it finishes off the cockpit very well.

The semi-flush deck (cabinsides tapering into nothing ahead of the mast) made my dad call this initial edition the 'blister-canopy' (as with the Supermarine Spitfire) or the 'bubble-top' (what they called the North American P-51C with Malcolm hood). Once a fighter pilot, always a fighter pilot....

The rig is tall and the boom short, typical for an IOR-influenced boat of this period-- it's technically high-aspect. The narrow stern is an IOR feature as well, meant to get the smallest-possible girth measurements to 'defeat' the rule. Still the boat rates 19.4, not 18.0; and so it is not a quarter-tonner.

The narrow stern actually makes the boat appear and behave very much like a double-ender, being responsible for the boat taking a following sea rather well and leaving the water close to the way it found it (if the outboard is not too heavy or kept down).

Notice that the mainsheet in this drawing goes straight down to where Diana's bridgedeck-mounted traveler goes. ;) Also the plan drawing appears to indicate a bridge deck, which was not as-built.

I just noticed that this drawing shows the deck having scalloped handrails, not those little teak sticks that went on production boats. They also appear to extend a little too far forward. By some bizarre coincidence (for I did not examine this before I made them!) the handrails for Diana look exactly like the ones in this drawing.


The parallelogram keel is a sign of the times (1972). In 1974 it would have had a vertical trailing edge. The semi-skeg in front of the rudder is as well; in 1976 my dad would eliminate all but a minor dimple there on the Raider and by 1978 he had said he should have done without it entirely.

Other than this, the Raider 33 looks like a direct descendant of the Hunter 25. Both boats are noted for early heeling, stability once heeled, good pointing ability and the tendency to be driven hard by the jib (throttle) and steadied by the main (shock absorber). I call this a 'hellandback' boat, because that's where it'll take you.

Surprise, surprise

Here on poor Diana the V-berth area has been the last part of the interior to get any attention at all.  One of the first things I did was to install the holding tank under the after end of the bunk; but since then it's been partially dismantled and not much has been done here.  (Stay tuned for a forthcoming post on this compartment when the through-hulls go in.)  The V-berth area has been used as a lumber bay for too long.  The other day I cleared it all out and stashed the usable lumber (mahogany, spruce and white pine) in the house's attic.  By the time I had swept and vacuumed out the V-berth area I felt like I had got a huge load off my conscience.  Suddenly there is actual space in this boat!

And the boat must have lost 200 lbs as well!


Here is a (lousy) photo of the V-berth right after I swept and vacuumed (for the first time in I won't say how long!).  The 5-gallon pail full of wood bits (mostly Honduras mahogany) is the only remainder of the once daunting heap that formerly occupied this space.













While laying out the forepeak lockers (more on this later too) I observed that the 3/8"-plywood bunktop felt distressingly flimsy.  Just kneeling on it was enough to bend it far too much out of level for my liking.  I have already done all the other bunktops, removing the old cleats for the lift-out panels, installing new ones saturated and bonded with epoxy and peppering each one with plenty of #8 screws.  Each time the bunktop has become stronger and stiffer.  If these bunktops are 'glassed to the hull-- and they are-- they should be structural members in their own right-- and so they are, now.

Hunter used plain white-pine 1x2s for lift-out cleats, the same as you buy at Lowe's or Home Depot.  Some of them had edges that had been smoothly routered to about a 1/4" radius, in order to protect your knuckles when you are rummaging about in the compartment.  But even if they were glued to the plywood with wood glue (and some of them, like the V-berth ones, were not) they were merely painted with Pettit Fiberglass Undercoater and otherwise left alone.  In the middle compartment under the V-berth, three of the cleats were sound enough that they did not require replacement (at least, not today).  The cleat along the aft edge was both too loose and too short to lend much stiffness of the bunktop.  So I removed it and fashioned another one out of a piece of 1x3, essentially the full width of the bunk at that point (about 34").  Properly fastened (with screws and then cured epoxy) it will stiffen the whole structure.

Inside this compartment was a straggling bit of old electrical wiring, leading through the bilge to the rode locker for the port and starboard running lights in the hull.  All right; first, I never run wiring through the bilge.  All my new wiring is run under the hull-to-deck flange.  There it's accessible and out of the muck.  Second, this wiring is red and black, and also 16-gauge, neither of which is code for boats any more; so I have run all new red-and-yellow 14-gauge and so this wire is redundant.  And, third, I am not reusing the port and starboard running lights in the hull.  They are too small and too low to be of much use except when motoring through a calm harbor at night.  Diana will get a one-light red-and-green unit, with an LED bulb, mounted on the pulpit.

I tugged and tugged on the wire and realized I could not pull it out.  Sure enough, the wire disappeared through the middle compartment's forward bulkhead, passed through the dead-air space and emerged at the bottom of the rode locker.  Obviously the entire interior structure was assembled outside the boat-- and all the wiring stapled to where it should be-- and then installed in the hull in as close to a completed state as possible.  This is how Hunter built five of these boats each week.

Now I despise all dead-air spaces on boats.  If it's inaccessible to humans, rest assured it won't be to humidity, bugs and bilge water.  Who knows what might be going on inside there?  And an application of Murphy's Law ensures that if you have a problem leak, or hidden rot, or a bug infestation, it's going to be in the one compartment into which you cannot readily get.  I had already resolved to open this compartment, at first by installing an 8" clean-out plate and then, in interests of simplicity and economy, just cutting a lift-out hatch into it and adding fiddles.  Also it would give me the chance to inspect it and to apply some epoxy to what I was sure was bare plywood in there.

Following this philosophy I have already cut access holes into the feet of the settee berths which extend through the main bulkhead.  Formerly these spaces were inaccessible and yet open for leading wiring and attracting humidity and bugs.  Now the one to port is convenient for installing and maintaining the Whale footpump for the head sink.  Both these new-found compartments are done now-- but one lacks a lift-out panel as I just do not have any scrap 3/8" plywood, since I don't like to use it for much of anything.  I do have some specific need for a sheet of it soon (more on that later) and will remake a lot of the old lift-outs till it's all gone.

I laid out an opening of about 9 inches square and rocked the jigsaw in to avoid drilling 3/8" starter holes and to save the cutout to use as the lift-out panel.  A can of Krylon supplied the corners' radius.  The piece of plywood came out perfectly-- and then, for the first time in 37-1/2 years, a human being gazed in at the compartment beyond.  And-- what a surprise.


This photo shows the space after I sanded some of the fatigued paint and got ready to install the new cleats.  At the forward end is the new hatch, about 9 inches square.  It might serve as a secondary rode locker if my idea of the plastic trash cans doesn't happen.  This is one storage space Diana now has that most H25 owners don't even know about!  The bare wood at an angle in the center compartment is the new white-pine cleat that just happens to be lying in the space (had to check if it was not too wide for it).
Having seen the top photo you will notice I started peeling off the old hull liner.  This chore is not particularly hazardous but really makes a mess.  I have invented a vacuum attachment that has a 6" putty trowel and a tube for a handle that plugs into the vacuum hose, expressly for doing chipping work (what we at CBC called 'pachippulating') like this.  I'll try it out here (rest of hull liner is already off).  Really the hull liner up here is not in such bad shape and you can see it's had good adhesion.  But it's dry and a little crispy and Lord knows how clean it is.  I am replacing it with the 'Irish tweed' stuff from Defender.

What I found in this cubbyhole was remarkable.  I had been particularly distressed because the accumulated junk, that had been condemned to remain in the middle compartment till I cleared out the lumber, included a two-foot length of rope that was sopping wet.  From where did the water come?  The rest of the compartment appeared dry.  The bits of scrap wood in there with the rope were damp but nowhere near as wet as the rope.  The hawsepipe on the deck is taped over against weather.  All I can account for is that the holes from the stem fitting that was removed (see them in the top photo) are still open, though on a negative angle, and rain and snow must have been blowing in there all autumn and winter and running down through the rode locker and the dead-air space to the second compartment (though I never noticed water in the holding-tank one beyond, to which all of the forward ones drain).

But, no worries.  The dark-green glass of the inside of the hull, at the very end of the bilge, appears sound, strong and-- most surprisingly-- dry.  Even more surprising, so does the plywood.  It is not damp or dark or even smelly.  For some unfathomable reason the untreated wood, which should have been a totally gooky mess in a compartment that admits drainage water but no air, has remained bone-dry and free of rot and mildew for over three and a half decades.


This 'first look' at the newly excavated space shows perfectly healthy dark-green fiberglass resin, a tight layup, no evidence of water intrusion or delamination and, best of all, no damp or rotting plywood-- even though the plywood surfaces were all unfinished (and I mean RAW plywood-- no paint, resin or-- had Providence intervened-- epoxy (which maybe no one but my dad had heard of in 1974).

The little black circles on the bunktop are my marks for the screw holes.  There seem like so many! --but keep in mind four pieces of wood have to be installed here.

The grey stuff along the one side looks like oozed-out deck putty.  I do not think (nor hope) it's a mud-dauber nest!  But really there could have been anyone living in here; and there is no one.

The stick lying at the forward end is an old cleat being reused as the new forward cleat, yet to be installed in this photo.  I always make cleats as long or wide as possible to add stiffness across the crosswise grain of the merely-3/8"-thick plywood.  Properly adhered, a new cleat does wonders.

I reused another removed cleat for the after one of this hole.  Being 1x2 stock (1-1/2" wide) it goes smack up against the forward face of the after bulkhead of this compartment (at the bottom of the photo).  I planned it like this when I laid out the opening.  This way the after edge of that cleat is adhered with epoxy to the face of the bulkhead itself.  In many cases the tops of such bulkheads are where moisture intrudes to generate rot, since the bottom edges, along the hull, are typically better treated when the boat is assembled.  I really do not relish the thought of replacing an under-bunk bulkhead, especially when it's so easy to avoid ever having to do it.

The bits of plywood to the sides are a piece of scrap that I found in the 5-gallon pail of blocks and cut to fit (notice the one under the flash came from the end of the other).  I don't care about their shape-- you only see the parallel edges in the access opening and these bits of plywood have been, as of this writing, thoroughly saturated in epoxy and well-adhered to the underside of the plywood, which I also saturated before installing the fiddles.  As soon as I drill a 3/4" finger hole in the cut-out panel it will be painted in epoxy too and replaced as the new lift-out panel.

I will post photos of how these silly cleats and all have gone together after the epoxy dries.  This whole space, including the underside of the plywood, will be painted in epoxy later and then in white Interlux Bilgekote as soon as it's warm enough to ventilate the space and enable paint to dry.  The bunktop will get done in Durawhite (or whatever the new water-based mildew-resistant paint Pettit is offering now that replaces it).
 
I have not yet decided if it's worth it to extend PVC drain tubes from each of the forward compartments into the after one (where the holding tank and through-hulls are) in order to isolate them from each other.  Any of these might make a very good stash hole for bottled water, blankets, sweaters, boots, and various gear; and as with the one under the cockpit it would be really nice to keep a mishap in one (or water from the hawse pipe) from wetting them all.  Plugs in the ends of the drain tubes would keep them dry till you needed to evacuate them.

An argument-ender and a joyous surprise

Here is another funny bit which I hope will support some of the points I have so often attempted to make about the lack of absolutism when it comes to maintaining quality in a boatbuilding enterprise.

Many times a prudent selection of materials or methods can facilitate significant savings to both the builder and customer without sacrificing utility or durability in the product itself.  Intelligent boatbuilders and designers know where 'good enough' is good enough; and I submit that no engineer in a non-boating field, and certainly no wannabe, should stand on ceremony as to ideal technical specifications when the boatbuilder and designer far outrank them in terms of knowledge base, expertise and focused training and experience.

And so, to the positive example.  How many have claimed that marine plywood is the sole material in use on production sailboats?  I have rebuilt the whole interior of Diana without using a single bit of it; in fact my material of choice is lauan cabinetry plywood, well saturated in WEST epoxy and properly finished in paint or sealer and varnish.  None of this is inadequate when properly done .

Having just cut open the forward end of the vee berth to give access to the forwardmost compartment under the bunktop (in another post here), I took the cut-out piece to the bench to sand its edges in order to use it for the lift-out panel.    Turning over the 9-inch square of plywood I made a startling discovery.


(And how on earth did I happen to choose the exact right place to cut out so that I could have this message appear on the back of the panel?)

If you cannot read it in this photo, here is what it says:

'Roseburg' [name of plywood mill]
'Resin Tite' [trade name]
'Hot pressed' [lamination process]
'Exterior glue'

Hah! --the bunktop in this 1974 Hunter 25 is AB-grade exterior fir plywood-- not marine plywood.  This raw-- unpainted, untreated, unfinished-- piece of plywood has survived 37-1/2 years, much of them seeing little maintenance or attention, in a cheap production sailboat used almost exclusively in a saltwater environment on the New Jersey shore.  This very piece came from a closed-in, dead-air compartment with no ventilation which no one has laid eyes or hands on in all that time.  And it shows NO signs of rot, water saturation, mildew, dampness, discoloration or anything.  It's as healthy as would be a piece of plywood stored in your attic.  Simply amazing.

Just so you know.  :)

Naughty, naughty, Hunter Marine!

These two photos clearly indicate the level of quality control at Hunter in the early 1970s.  The one at right is of the lift-out panel for the center compartment under the vee berth.  The one at the bottom is of the after one (under which is the holding tank).  Looking closely you will see my notes in Sharpie pen about how to adapt these for use as templates when I cut out new panels.  Each is easily 1/4" too small for its space.  This matters when the fiddle below it is only 3/4" wide.  A little bending from weight centered upon the 3/8"-plywood panel could easily bow it enough to break it, especially since it is 37 years old.


Also, these panels are much too large to do without reinforcements underneath.  When I make the new ones I will apply white-pine sticks, 3/4" square, to the undersides using epoxy.  Like ultralight-airplane wing ribs, the size won't matter as much as the fact that they're there and adequately secured so as to be structural.

By the way, when I designed interiors at Cherubini I always specified 3/4" plywood for bunktops, especially doubles.  Even so these still require some honeycombing of bulkheads underneath to lend stiffness and strength.  I would consider reducing this thickness and weight to 1/2"  so long as the bulkheads below were well secured, well treated in epoxy and numerous enough to lend the required rigidity.  I would never use 3/8" for a bunktop under any circumstances-- unless those circumstances were that the 3/8" was already installed on my antique boat!

I simply cannot wait to paint this area; but there are lockers and stuff to install here.  This was the space in which I stored raw lumber during the rest of the project and it's only become clear again recently.

The quarter berth

The first-series H25 came with a 12-foot-long berth to port.  Having come up with the original concept for this interior when I was 14 or 15, I suggested that the ‘nav station’ be its own little cubbyhole but got vetoed by budget and marketing at Hunter, perhaps the first of many rude awakenings over the years about how these two departments, not engineering and design, govern how boats get made.  So when I got an H25 for myself I was determined, as with the bridge deck, to rectify this fault and create something cooler about my boat for myself.
 
Immediately ahead of the quarter-berth I added a bulkhead to correspond to the forward bulkhead of the galley on the other side.  In this photo the camera is leaning on the vertical grab post that terminates the inboard end of that bulkhead.  But the original space was only 12’0” long, a kind of head-to-head double bunk.  Putting in this bulkhead left the quarter bunk about 5’8”.  So I would extend it.

Fortunately on poor Diana, the after bulkhead here, at the foot, being the mounting space for the (dumb) idea of the gas-can locker, had got so rotten from the boat’s being operated with the hatch open in rain that I was able to remove it... with no tools.  One of the first things I did was to build a new bulkhead 9 inches farther aft and make a shelf over the foot end.  It appears as a winch-handle shelf in the cockpit-seat hatch.  The same shelf extends forward over the foot of the bunk, making a duffel-bag locker there (see the one at the far end, here cluttered with small boards and other stuff).  The lockers along the side were an afterthought.  I had a piece of wood in my hand, going around the boat fitting it into places, and suddenly got the Eureka idea to make what we used to have on C44s up front, the underwear, t-shirt and swimsuit ‘stuff lockers’ over the bunk.

This side locker face was VERY hard to fit properly.  There was no structure here to rely upon-- I was measuring things in thin air.  It is not parallel to the centreline nor to the angled side of the bunk.  Immediately forward of it, in the space where the fiddle-rail shelf used to be, is the electrical panel.  (In the photo the panel is lying back in the bunk with two rectangular holes for the switch panels.  It appears here face-down; the switch panels are to the right when you look at it.)  This was hard to fit against the back of the cabin but I finally just left the end long and figured I’d make some kind of bin in the back end, over the end of the fiddle-rail shelf.  This end of the electrical panel actually formed a good anchoring point for this new locker face.  I mounted it with no bottom and cut the bottom to fit.  It’s bonded to the hull with 5200, lending strength and stiffness in this notoriously flimsy area.
 
The fit of the overhead of this space has yet to be determined.  I intend the roof of the locker for the shotgun but have to install the traveler and backing plates before I can see what I have to screw the hinges and latches to.
 
The bit of what looks like plain trashy plywood in the back of the crosswise locker is a bit of plain trashy 3/8” CDX plywood I had been using for templates and the like till one day I got the silly idea to make dividers for these lockers out of it.  Diligently I fit the pieces, sanded them carefully (try sanding CDX some time!) and saturated them in Salem sealer before installing them.  As such they’re adequate for humidity and will last ages.  Another divider is visible beside the blue duffel bag.  One of them I signed (before the varnish and installation) as a tongue-and-cheek reminder to the next owner that I really did know what I was doing using this plain trashy plywood and that it was meant as a joke.  The one in the back blocks off a ragged piece of ‘glass from the earlier bunk-foot structure.
 
The little cubbyhole down at the far end is where the original after bulkhead was-- its forward bulkhead is heavily ‘glassed to the hull.  The two blades of ‘glass after where I cut it off have remained strong even though the wood between it was rotten to nothing.  There’s still some (good) wood in there.  The inside of this locker isn’t pretty-- I put it there mainly to trim off the remains of what had been there.  I had to make a floor in it, uncharacteristically blocking off the space below to keep things from disappearing into an invisible and almost inaccessible wedge in there.  I call this locker ‘Indiana’ because its plywood face is the shape of that state only mirrored.  Beneath the foot of the bunk, beyond the original bulkhead (still there under the bunktop), is another locker against the inside of the hull.  If you were to peel up the front of the mattress some day you would assume there are only the two stock traps under the bunk; so it might be a good hiding spot.  But I’ve just said that in this blog; so you can rest assured that’s not the only secret spot this boat holds!
 
I will take other photos of the under-cockpit area and the ladder but I have been waiting to pretty it up with more trim.  I have been going up and down that ladder about 6 years now and only recently have I considered that the treads might like another coat of varnish.  Captain’s Varnish is made for spars and is excellent for durability as well as UV protection.
 
The trim around the lockers came from C44 hull 5, which was in for restoration while I was collecting scrap wood.  The wood is only 3 years younger than this (1974) boat.  The trim around the teak cabin back looks washed-out from the flash, but it is really more golden than the long-varnished other stuff, and it is all Honduras mahogany (not the pretend stuff you get now).  I just screwed it on and let the screws show-- it’s too thin for plugs and it’s how the trim was originally on this boat.  I also don’t believe in staining wood that’s already pretty.  I leave it as-is, apply sealer and then Captain’s Varnish and let it have its own identity.  So the interior appears a mix-up of varying wood colors, which is exactly how it should be.  It reflects the reality and naturalness of the natural material.  (Also it is much less work.)  I tried a bit of stain on a bit of mahogany-plywood bulkhead and even though I used only a very little it got so black that it was downright ugly and I remade the piece and just varnished it as-is. Varnished mahogany marine plywood, going back to the Cherubini Sea Scamp days, is as much of my heritage as are original artwork, Roman Catholicism and frozen waffles.  In this boat I am surrounded by what I am.
