Thursday

Now that the paintwork on the centerboard trunk repairs was complete, I removed the masking tape.

Next, I reinstalled the two wooden seat assemblies; each had six screws to secure it to the support cleats beneath.

With that, the project was complete.

Wednesday

I began with a light sanding of the first coat of finish paint on the centerboard trunk repairs, after which I cleaned the area as required and applied a second coat of the Hatteras off-white with flattening agent mixed in.

To finish up the small hull repairs at the stem and starboard bow, after final preparations I masked off the areas with foam tape and masking paper, then, over the course of the remainder of the morning, sprayed on three coats of gloss-white LPU topcoat that matched the existing hull finish and paint system.

Later in the day, the paint had cured to the point that I could remove the masking from both areas.

With just a few final details to take care of, I expected to complete work on the project next time.

Tuesday

After lightly sanding the all-over primer and cleaning and preparing the area, I applied the first coat of finish paint.  To match the existing interior color, I happened to have a can of Hatteras off-white on hand, leftover from something or another, which was a reasonably close match.  I added some flattening agent to the paint to tone down the gloss, as I didn’t think the finish should be high-gloss on the non-smooth centerboard trunk housing.  The paint still appears glossy in the photos since it was wet at the time, but I’d judge whether to add more flattener to the second coat once I saw how the first coat turned out.  I hoped two coats would do the job.

After lightly sanding the through hull patch on the starboard bow, I applied a couple coats of the epoxy-based primer to the fresh epoxy, which would allow me to do the topcoats next time.

Monday

Now that the “tie coat” primer had had the weekend to cure, I could lightly sand it to prepare the centerboard trunk repairs for the next step, which was an overall coat of one-part primer to cover the entire trunk and repair area.

After a light sanding to the patch at the old through hull location, I applied a coat of epoxy fairing material, keeping the work as contained as possible.  The old eyebolt hole at the stem was basically fair and ready for paint whenever the larger through hull repair was ready.

Next, I continued work on the brass rubstrip, this time on the starboard side.  As before, I laid out a strip of tape onto which I marked existing screw (and broken stud) locations, then secured my flexible tape measure in place so I could locate all the new fasteners accordingly.  Fortunately, with only a minor manipulation here and there, the new spacing worked out well to avoid all the existing screws.

Using temporary clamps as loose guides through which to thread the recalcitrant rubstrip, I taped the metal in place along the rubrail as needed, keeping the forward end aligned with its counterpart to port.  Then, for each screw location, I went through the 5-step process to install the fasteners:  center punch; pilot hole; larger pilot hole for the screw shank; countersink; and finally install the #6 x 1/2″ oval head bronze screw (Freason).

Working my way down the boat, I secured the new rail, adding a short length as needed to reach the corner of the transom.

Then, I repeated the layout and installation process for the final length of rubstrip across the transom itself.

The epoxy I’d used to fill the old fastener holes at the lower gudgeon location had had ample cure time, and now I used the new gudgeon to lay out for its fastener holes, keeping the outline of the gudgeon itself aligned with the shadow of its predecessor.  Since there was no access within, I used bronze screws to secure the lower gudgeon in place with lots of sealant.  For the top gudgeon, I secured it with more sealant and two 1/4″ x 2″ bolts through the transom, since the inside was accessible for nuts and washers.

All that remained to complete the project was to finalize the paint coatings on the repaired centerboard trunk and other minor repairs in the hull, which I’d complete over the next few days as necessary.

Friday

After a light sanding–much of it by hand because of tight access–I deemed the centerboard trunk repairs ready for primer.

Because one-part paints and primers don’t cure properly over fresh epoxy, and because schedules always demand moving forward rather than waiting some days or weeks for the epoxy to cure sufficiently to allow these paints to work, I always apply what I call a tie-coat of two-part epoxy primer, and this was my next step.  After masking off the area as needed for the primer and subsequent coats of paint, I applied a coat of the epoxy primer over the fresh work (staying away from the existing painted surfaces, which I imagined were one-pack paint).  Should any further fine-tuning of the fairing work be required, I could take care of that once the primer was cured and sanded.

To complete the structural (as it were) part of the through-hull hole repair, I applied two layers of fiberglass over the inside of the patch, and a single layer of light cloth over the exterior.

Afterwards, I completed the brass rubrail installation on the port side, working my way down and installing fasteners every 6″.  The length of the boat required a short second section of the rail to reach the transom.  I’d planned on doing the starboard side during the afternoon, but a change of plans required my presence elsewhere.  With a few days ahead requiring short painting sessions, I’d easily finish up the rest of the project list early in the week.

Thursday

My first order of business was to prep and lightly sand the new fiberglass work on the centerboard trunk, just easing any sharp edges and scuffing the surface to prepare for the next steps.

While I was at it, I prepared a couple other small areas of the boat for repair:  an old hole leftover from a bow eye system the owner didn’t want, and an inexplicable plastic through hull mounted below the rail on the starboard bow.  After removing the through hull, which was just screwed in place with no sealant, I prepared the hull for a fiberglass patch inside and out, keeping the outside area as small as possible to minimize paint patching.

After final preparations, I applied a coat of epoxy fairing compound to the centerboard trunk repairs, mainly to fill the weave and clean up the transitions at the edges of the new cloth.   I anticipated that the one coat of filler would be sufficient to match the texture and appearance of the surrounding areas.

Meanwhile, I filled the bow eye hole and the hole leftover from the through hull with leftover thickened epoxy.

The wooden toerail and rubrail had been stripped to bare wood sometime in the past, which is how the owner wanted it, and now I prepared to install a new half-oval brass rubstrip on the exterior face of the rubrail.  With numerous screws holding the wood to the boat, and broken-off studs of the old screws leftover from the original rubrail, there were many impediments to future screw placement.

Starting with the port side, I laid out a strip of masking tape along the rail, which gave me a place to mark all the existing screw and broken screw locations.

The brass stock (bronze half oval is not available other than, I suppose, through custom order) came in 12-foot lengths without screw holes, and in the 3/8″ x 3/32″ size required for this boat, was delicate, easy to damage, and hard to control at the early stages.  I planned to drill and countersink the rail in place to avoid trying to move the flimsy material when full of screw holes, but first I had to tame it enough to get it in place temporarily.  I used a few clamps over the rail to help hold the rub strip roughly in place without bending, while I secured it more permanently with masking tape every so often along its length.  Then I laid out a flexible tape measure and, keeping clear of the various old and existing screw locations, laid out the new screw locations every six inches on center.

Starting at the bow, I began to attach the rail with #6 bronze oval-head wood screws.  At each location, I center-punched; drilled a pilot hole through the brass and into the wood; enlarged the pilot hole through the brass for the screw shank; and milled a countersink for the screw head.  As proof of concept, this procedure worked well, and while I was out of time for the moment, I expected the rest of the rail installation would proceed accordingly.

Wednesday

After getting set up with tools and equipment, I prepared the area around and including the centerboard trunk for the intended repair.  With flaking paint here and there along the full length of the tabbing seam where the cockpit sole had been secured to the trunk, I decided early on to grind away the paint and any loose material from the full length of the trunk, not just the forward section that I’d pinpointed as a possible cause of the water leakage into the keel sump.

This was a disproportionately unpleasant chore, but eventually I’d removed paint and loose material from the lower 6″ or so of the cabin trunk, spanning the original tabbing seam and extending to the bottom of the trunk where it met the recesses sumps, and around the myriad corners and crevices of the remnants of the old forward bulkhead, which had been mostly cut out during the much-earlier cockpit modifications.  This preparation would allow the new tabbing to bond sufficiently in these areas.  In the seam where the cockpit met the cabin trunk in these areas, I found some soft adhesive/sealant-type material in the corners; whether this was part of the original construction (which seemed odd) or whether it was a more recent attempt at a fix I did not know, but in any event I scraped, with some effort, all this material out of the various crevices.  While I was making a mess, I also sanded the whole remainder of the centerboard trunk to prepare it for repainting when the repairs were done.

I also inspected the centerboard trunk and pin from below the boat, where I had a relatively clear view.  In discussions with the owner, some of the original details of the centerboard pin and its installation became more clear, and for a while we debated whether to install inspection ports in the cockpit above to access–or even replace–the pin in case that was the source of the leak, though we also now knew that rainwater in the cockpit did eventually and slowly drain into the sump; whether that was the only source of the water, or whether there was still and outside source, was as yet unknown.

Since I could confirm from below that the pin was in good shape where visible and made from bronze, we ultimately decided not to install deck plates at this time, largely because any deck plates in this cockpit would simply leak into the bilge, defeating the whole purpose of the modified cockpit arrangement and not in keeping with the original goals.  Should problems persist, or the centerboard pin require maintenance later, we’d re-address the issue then.

After cleaning up and preparing new fiberglass for the areas I’d ground earlier, I applied a heavy epoxy fillet around all the forward portions of the centerboard trunk and where it conjoined the vertical remnants of the bulkhead, not only to fill and seal the corners of the juncture, but also to ease all abrupt transitions for future fiberglass work.

While I left the fillets to gel, I removed the old bronze gudgeons from the stern.  The holes for the lower gudgeon near the base of the skeg were ratty, so I reamed them out a bit and filled with a strengthened, thickened epoxy mixture so I could redrill the holes for the new gudgeons as needed.

I took a minute or two to pare away and lightly sand the bungs on the replacement cockpit seat slat, completing the seat repair for now.

When the fillets were ready for the next step, I wet out and applied biaxial tabbing to the centerboard seam, and around the forward corners, using a few layers of lighter cloth as needed to cover and seal the tightest corners (mainly around the slim bulkhead remnants) that the heavier material couldn’t handle.

Tuesday

During a short work session, I completed the repair to the port cockpit seat.  I got started by unclamping the glue-up I’d finished earlier, then running the assembly through the planer on both sides to reduce its thickness by nearly half, from about an inch to start, down to a final dimension of 9/16″ thick to match the existing seat slats.

Now I could lay out the shape of the replacement board using the mirror-image starboard side as a pattern.

Thus marked, I cut out the shape and smoothed and finished the top edges of the new plank with sandpaper.

Shaping complete, I secured the new plank to the remaining part of the port seat with two screws at each cleat location, and bunged the screw holes.

Exhausted by the long hours and brutal work, I turned in for the day.  (Actually, I had other business to attend to away from the shop in the afternoon.)
