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.

Diana's new stemhead fitting

I never liked the three-legged Hunter 25 pulpit and meant to replace it with something cooler from the very start.  This would mean cutting off the 7/8" stainless-steel stud from the stemhead fitting and polishing it over; but as Diana's PO had put her into some kind of close encounter with a piling, the original stemhead fitting was quite mangled and badly restraightened.  So I determined to make a new one.

I designed a very nice replacement part for this but found no one to make it at a reasonable price.  Then I happened to stumble across one on the Racelite web page and ordered it.  Though the dimensions on the site represented an adequate part, the actual thing seemed to represent them only nominally-- the thickness was not a true 1/8" and the length was entirely too short.  Rather typically I sat on this problem for over a year, working on other things, while I contemplated some solution.

Finally I ordered some flat stock, cut it to length, and sent it out to the local welders' with a pattern of the correct angle.  The part I received was simply beautiful.  I have begun to polish it and will finish it off before it's permanently installed.


You can see how the original part was only about 60 percent as long as it needed to be along the stem.  The flat stock welded to the part effectively doubles the thickness for the first three holes.  It is true that the tang for the forestay is still of the thin (original) stock; but as it's already thicker than were the shroud tangs I'll install it as it is and see if, as the rig is tuned, I get any elongation of the hole.  If that will be the case (which I doubt) I'll have it remedied with more welding.  As this Racelite part is meant for 20-to'22-footers, and as it's already meant to carry the load of 1/4" clevis pins, I'm betting it won't ever be a problem.


In this pic I have set the part on the bow to check the fit.  Thanks to my template the welder's work resulted in a perfect fit. You will see the gap behind the very top of the fitting-- this requires attention.  If I were to mount this as-is, two things would happen: Diana's J measurement (foot of the headsail) would be longer than that of a stock Hunter 25 by about 7/8"; and the natural stresses of a tuned and ruggedly-used rig would attempt to bend the fitting aftwards, putting the single screw through the deck into a shear load, and some distortion would occur.  This is why it is never wise to suspend rigging attachments over air, as would be done here.  I will fabricate a little block for in this gap, just something to support the compression load, and 'glass or epoxy it into place prior to paint and prior to attaching this fitting.

The horizontal pencil lines are marking where the mounting holes will go.  Only one of the original holes lined up.  I have a mahogany backing block for this, to be bedded in 5200 inside, and will drill new holes for the 1/4-20 hex-head cap screws.  Hex-heads are best for this sort of thing because you can put a ratchet and socket on each one and really tune them well.  Large-scale Phillips and, worse, slotted-head screws are really kind of pointless after a while.  A larger screw implies a larger load which means installation torque matters more.  No one can apply appropriate torque with a screwdriver handle.  I think the only reason people dislike hex-headed cap screws is because they make the boat look like Frankenstein's monster.  Personally, I like the look.  It's its own aesthetic.

The evident damage to the bow was from the PO.  The starboard-side toerail was cut to facilitate the fiberglass repair and reattached.  Coincidentally, this piece will have to be cut down to accommodate the anchor roller.  I'll fill the seam in the toerail with black 4000-UV to minimize the appearance of a crack.  Much of the old fiberglass repair was faired over with 3M filler (the grayer stuff).  The darker brown-olive is raw fiberglass from my sanding.  I have filled all the imperfections with both Evercoat 27 and epoxy and after painting with epoxy paint (Perfection or Brightside) this won't be visible or vulnerable.

The brown thing above the deck is the work-order tag from the welders'.  Mistakenly they wrote it up as being for my cousin Dave's shop; but this was my project and I contracted and paid for it.  (This happens a lot, actually.)

Sales pitch #1

If any other H25 owner is interested in having one of these parts, I will be happy to supply it.  It does, however, require a 4-legged pulpit; though I'd consider that an improvement.  I've designed an updated bow rail for Diana, along the lines of a J27's, complete with step-through end, varnished-mahogany seat/step with nonskid, and mount for Aqua Signal running light; though I'll be installing a plain-Jane castoff pulpit from another boat for the short term.

Sales pitch #2

Yes; the boat beside Diana, evident in one of these pics, is one of her sisters-- in this case a fellow February 1974 boat, this one the later trunk cabin/pop-top model.  They are both of the same series, Diana being number 027 and the other boat being 140.  At that time Hunter had two production lines of H25s at their Marlboro, New Jersey, plant; and I believe that the "0" signified the period's production series of "blister-canopy" or "flush-deck" models and the "1" signified the trunk-cabin models. If these boats were not on the production floor at the same time, they are probably not more than two weeks apart in age.

I have been referring to this other boat as "the sweet sister" and  hope to enter negotiations with her owner to take over her care and to restore her-- for she is still, even with an inadequate cover, in better condition than Diana was when I first found her and would represent a pretty easy, quick and profitable "quick fix" and resale.  She'll need some deck-core repair, paint, new cushions and upholstery, lifelines and probably cordage; and I do not know if there is an engine available.  But it wouldn't take much more than that for her to go sailing again.  As soon as Diana goes in I will have this boat shrink-wrapped and set a dehumidifier in her, to help preserve her.  Anyone interested is welcome to get in touch.

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.
