Winter 2018-2019

For those still interested - boat DID NOT get painted, due to lack of help. Now earliest launch date is late May. That’s how it goes - you miss a three-week window, you wait 9 months.

Yes; basically this means I had $350 to have the boat covered but could find no-one to help paint. I shall hire the lads at the yard to help as soon as I can take off the wrapping. They'll take my money.

Pics do not show it but progress is being made. What you do not see here:

I have been buying and trading sailboat hardware on eBay for years but lately it has become most productive.  Most recently I acquired outhaul blocks and blocks for running backstays.

I designed the in-boom outhaul-rigging system and figured out where and how to cut off the back of the boom (it was designed to reach the aft end of the cockpit, where the mainsheet would go; but having installed a bridge deck for the traveler I no longer need so long a boom and will cut it off more in keeping with the E measurement which is 8 ft.).  You'd better believe I won't cut it off till I have the boat actually rigged with sails on though!

I designed the tang for jiffy-reefing line and for topping lift.   Machinist extraordinaire John Steinmacher promises to help with this.

I have enough winches.  This is important because they all have had to be 1970s-1980s chrome-plated Lewmars, in keeping with the boat as a ‘period piece’; and most people do not replace these - as they are too small to come in self-tailing models, so what would be the point?  Two of the ones I have need to be replated.  Anyone know any decent plating shops?

I cleaned out the whole boat.  This is incredible progress.   The poor boat has been a toolbox/woodshop for so long it’s actually kept work from being done.  Of course everything now is scattered all over the steps of my house; but the truth is I have very little major woodwork left to do and am no concentrating on finishing the plumbing and electrical system, ripping out and replacing a rotten bulkhead to fit in a refrigerator box, and finishing a few things on the deck as well as can be done under the Shrinkwrap.

The daunting storage bill is the worst problem.   Anyone know better places for crowdfunding than GoFundMe?

Listening to WXPN 88.5's '885 best and 88 worst songs ever' countdown

24-25 October 2014

I delayed all work to prepare for this radio event, of which the 'worst songs' part was simply hysterical.  'XPN's program director Dan Reed deserves much credit, firstly for being an excellent DJ, providing information, context, and witty banter (as well as interviews with artistes and persona guests), and secondly for actually enduring all seven hours of the worst songs ever.

One thing I had to do was to move the speakers out to the cockpit to continue work on the hull.  On our Raider 33 Antigone we had cockpit speakers which my brother Steve made for his old Fiat, which had come with none.  They were nifty little white-overlay-plywood boxes with aluminum grilles and Sparkomatic 6x9s in them.  I came up with the idea (which I don't remember if we actually did) of mounting a Herreshoff-style cleat on the top of each one, to serve as a handle and a place to wrap the cord.  We just took these out and stood them on the cockpit seats whenever we wanted them.

For Diana I'm doing the same thing, likely with these nice little speakers which come from a 1980s Sony component portable stereo (which is currently in the boat).  I have already run the speaker cables back to the lazarrette but have yet to decide if I want to install connection points in the side of the little Dorade box or just to leave them below.  I hate how I screwed this little box to its mounting cleats; I should have used the cleat-on-cleat method that CY's Ziggy uses all the time as it hides the fasteners (provided there is interior access).  I will most probably plug these holes and add the cleats inside to do it that way... after the cover goes on and I remove the box for varnishing inside.

The Sea Dog low-profile vents are meant for the Dorade boxes on the cabintop.  The ones back here should be the taller traditional kind but as yet I have only ordered the low ones from Defender.

The one shown installed (and not totally pushed-in) is the one that vents through the Dorade box  and through a hose to the foot of the quarter berth.  It works great.  The other one leads directly through a hose to the bilge, where I have yet to fit a bilge blower for the gasoline vapors.  It is plugged here because, as Diana is not now swinging to weather on a mooring, I can't keep the cowl trimmed as an exhaust vent.

The patched hole in the cockpit was where I installed the Whale manual bilge pump, one of the first things I did when I got this boat as the cabin windows leaked like a sieve.  I decided to relocate it to the inside of the coaming, both because it's easier to operate while steering and because it'll free up access through this cockpit-seat locker.

WXPN is at xpn.org

The 'XPN radio event was really a lot of fun and I helped clog up Twitter with many comments.  As a result of the event's effect on listeners, '@885countdown' was the number-4 most-Tweeted event in the US on 24 October, easily number-1 in the Philadelphia region, and the station's own website crashed due to too much traffic.  Truly an event for the ages!

BTW: the number-one favorite song, as it had been at the last countdown in 2004, was Springsteen's 'Thunder Road'.  The worst one, on this, the first-ever worst-songs countdown, was Starship's 'We Built This City' (I am not making this up!).  And here I had thought 'Billy, Don't Be A Hero' was a shoo-in.

Waterline stripe

I've been getting frustrated that the progress I have been making on this boat does not look like progress; so I reached a limit recently and opened the can of Pettit Protect I've had for over a year and just went for it.  I cannot say this is a perfect job; there are minor spots in the hull I really should have faired better or filled better, and of course the first roller cover broke down after two coats and for the third I had to dig into my horde of stores for another which was too nappy and not as good.  But the paint's on the boat and that's good enough. 
   
I chose the Pettit Protect over Interlux Interprotect for one solid reason.  To reach the desired thickness, Interprotect requires five coats where as Pettit Protect requires only three.  It goes on thicker.  Therefore I accomplished this with only one roller replacement and in only about three hours of a hot Saturday in August.  
   
The rugged outline of the top edge of paint wants explanation.  In filling and fairing the hull's numerous cracks, I encountered quite a few of what I determined were 'bottom-style' cracks above the designed waterline, especially in the bow.  These are typical of any boat; and for a sailboat that one must conclude will be heeling more often than not, under way, the imposed delineation of a waterline is pretty arbitrary.  So I prepared these places as I would for any 'underwater' area; and once the waterline is established the gray can be sanded down above the line to accept topsides paint.   
  

The black Sharpie lines, applied at the upper edge of the green-tape stripe, will represent the lower edge of the painted stripe(s).  Thus I am 'cheating' the original waterline up about two inches.  

I lowered the rudder in its shaft tube but without digging a hole I was unable to remove it entirely.  As of this picture it has been sealed and re-'glassed (the yellowish stuff is epoxy, with some Microlight filler).  I found every seam in the rudder shell to have been open and filled with bottom paint (not a good sign), which was responsible for the whole thing being saturated in water.  As I used up all the Pettit Protect on the hull, I will have to buy more for the rudder and the stand squares.
   
From earlier photos one can see that I stripped the entire hull bare-- leaving no stripes.  Earlier I had plotted all three lines-- float waterline, designed waterline, and top of bootstripe-- and recorded the measurements.  These current lines come from those plots.
   

This sort-of-closeup view shows my 25-foot Stanley tape clamped along the toerail of the boat.  Using this as a kind of number line, I dangled the other Stanley tape from this, at prescribed intervals, taking 'soundings' down along the hull to the stripe.  To get the waterline back onto the hull, I had only to read my numbers back and to plot the marks from them.  
  
I am not sure I'm happy with the replotted marks.  Though I did the plotting accurately, I fear the boat is going to be too heavy, especially forward, and especially to starboard, which worries me.  To starboard are the engine-starting battery, the galley, the toilet itself, the toolbox, the primary anchor and (short) chain rode, and the microwave oven as well as the skipper's usual sitting area below, where the computer and stereo are located.  Everything else is more of less balanced out by a complement to the other side.  For now I shall let these lines alone and count on shifting some weight about (possibly by storing all canned goods to port, for example).   
   
In the background Jerry's 1980 C44 can be seen.  Jerry's a liveaboard who's been doing a heroic job stripping bad 'glass from his boat's bottom and re-'glassing the whole thing.  His stamina and indefatigable fortitude are an inspiration.
  
  
After taking some of these pics I just had to snap this view of Diana's underside all recently done in pewter gray undercoater (Pettit Protect).  
  
Yes; the keel looks a little bent out of shape.  Believe me-- it was much worse before I got my hands on it.
   
The paint does look a little blotchy in this view.  Maybe it's glare.  I can vouch for the effort than went into smoothing this; and the result really is pretty good.  Undoubtedly it's better than it was when new.  
  
The little oval block affixed to the bottom, aft of the keel, is the fairing block I made for the bronze drain plug.  Maybe it's just overkill; but, then again, every girl can use a little help....

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.

The keel-hull joint.

This was the single most problematic fault with the condition of the boat as I got it and, as it turns out, one of the most easily remedied.  Sometimes the dumbest fixes are the best ones.  (See the post on ‘Reverse-Mooyock Technology’.)  The PO had perceived either cracks or actual leaking in the keel/hull joint and was able to arrange the the yard’s Travellift to hold up the boat so he could loosen the keel bolts and apply new bedding compound.  Unfortunately he did not know his ‘caulk’ from his ‘bedding compound’ and apparently went into the marina store and asked for ‘caulk’.  Now caulking is used on wooden boats, to provide a watertight seal between planks that may not planed perfectly straight or do not meet perfectly together. The secret is that the compression of the swelling planks squeezes against the caulking and makes it watertight.  (I have heard stories of Barnegat Bay garveys that don’t use caulking at all; the yellow-pine planks swell terribly, jamming edge-to-edge against each other, from the first minute it’s in the water and after about three days stop leaking altogether.  This is why yellow pine is NOT code for house construction; and it's why pressure-treated deck lumber, which is yellow pine, changes dimensions over time.)

The PO should have asked for bedding compound which is meant to be phenomenally strong under tensile loads, opposite loads pulling apart from each other.  The often-infamous 5200, properly applied to clean surfaces, will hold 700 pounds per square inch.  It's meant for holding on lead keels.  Don’t even consider ‘caulk’, polysulphide, silicone or other such nonsense for this role.  Unfortunately my boat’s PO didn’t know that.

After too long a time worrying about how to fix this, the solution hit me almost literally on the head.  I bought some lengths of little 1/2” steel pipe intending to have the boat jacked up and then set down with those pipes lying between the hill and the keel, propping it up so I could reach in there, scrape it clean and rebed to reassemble the boat.  One day adjusting the jackstands I realized that all this worrying was idiotic-- the boat without the keel weighs
only about 2200 lbs.  So I loosened all the keel bolts, taking the nuts up to the top of the threads leaving about 7/8” to work with, and then under the boat I went about screwing the jackstands up.  I even put a prop under the sloping forward edge of the keel to keep it from toppling over (which would be catastrophic; for how would I pick up the fallen keel with the boat still on stands above it?).  Every day I went down and turned the stands another turn or so.  One day I was turning the stand under the bow with my back to the boat and and I heard a rubbery stretching noise behind my head.  I turned about and saw the ugly caulk parting from the keel-- the boat had risen about 3/4” from just the stands alone.  Once I got everything aligned it was a very simple matter to pick out all the residue to put in new 5200.

I scrubbed and sanded and scraped till I had two very clean surfaces in surprisingly good condition.  But I couldn't understand why the opened slot between the hull and the top of the keel kept appearing to be more in front than in back.  I kept adjusting the stands and still could not account for it till a fellow yard rat suggested, ‘The keel’s probably falling over.’  Sure enough it appeared that
the keel was probably leaning forward, in spite of the prop, and just walking the boat forward on all the stands.  How far would it go?  I wouldn't wait to find out.

‘Right,’ I said
to my daughter there.  ‘Tomorrow we get the 5200.’

I bought two fresh tubes, and the joint took that and all the rest I had lying about.  I just pumped in as much as the opened gap would hold.  Then we let down the jackstands and about half of it oozed out.  That got all nicely puttied over the whole seam area.  I made backing plates of G-10 and installed them in the bilge, leaving a space between the keel bolts for water to run back to the pump.  To preserve the threads from the 5200 (which would have barred any future adjustment) I wrapped the threads in masking tape.  Since then it’s been adjusted a few times, mainly to satisfy my worry, and it’s been fine.

One day my cousin Dave had to move the boat to the other side of the yard.  I didn’t know this was going to happen and when I heard I dreaded finding some disaster about my keel-bolt fix. The hull’s flexing under the load of the keel when it was picked up had caused my new cabin-sole joists to part from the hull-- but the keel-bolt nuts hadn’t even been torqued up properly and the 5200 held the whole thing on for the jaunt across the yard.  So-- no more worry as to that.
