November Update

With the cold wet weather upon us, focus shifts back to the interior. This time starting with the v-berth and forward head.

The V-berth is being planned as more of a "garage" for storage of stuff (sails, fenders, etc.). Stuff that could be wet and dirty. With that in mind, primary features are that it is well lit (to find stuff) and easy to clean. Does not need to be fancy and ornate. The first attempt was to put up plastic laminate on the bulkheads and cover the foam insulated hull sides and under-foredeck with a good quality vinyl. Then trim with hardwood.

Well, besides difficulties on laying up the vinyl in some areas, the compartment was looking like a sea of beige. The overwhelming color and given the vinyl was telegraphing every slight deformity of insulation on the hull sides, we have decided to go a bit traditional and clad the sides with strips of hardwood.

Which brings up the topic of tools. The current table top saw is just not big enough (size and power) to rip one and a half inch thick planks of hardwood. The most recent black friday gave an opportunity to remedy this with a new 3HP 220v table saw. which should see much use immediately.

On to the forward head The base for the toilet has been constructed and fitted allowing plenty of room for plumbing runs. The shower sump is under design with a planned plywood mockup. Actual construction material may be G10 fiberglass sheet and Coosa with a gelcoat finish. Interior finish is undetermined, but we are leaning to some sort of plastic laminate.

That is all for now!

Hull/Deck Joint Glassed, Too Late for Paint, Forward Head

Well, it looks like we missed our weather window for hull paint. Temperatures are too cold. Not a big deal as it seemed most of the summer was a bit humid anyway (not rainy, but a bit sticky). Oh well, with the semi-permanent scaffolds and new stairs built around the boat, we are ready for paint next year as soon as weather permits.

We did manage to glass the hull to deck joint. After removing the failed PlasTEAK caprail (experiment?) we decided to glass over the joint to improve strength and resistance to leaks. I wont bore you with the technical details, but will say the job goes smoother by wetting out glass first then laying on the joint, instead of laying out dry glass and wetting it in place. The latter tends to be more messy if you are not careful (epoxy drips over the side).

So for now we will leave the glassed-over caprail in place, unfaired and rough on the edges until the time comes to finish the deck. Until then, the caprail will get a sacrificial coat of paint to protected it from UV.

Forward Head


With the cool weather upon us, time to focus back on the interior. Specifically, the forward head, which, until now, has been completely empty. So far we have roughed in cabinet faces and approximated the 'settee height' for the toilet. Current thoughts are to build a equal height settee around the toilet. The picture shows a temporary plywood cutout as a rough approximation.

Vanity and sink will go here

Earlier in this blog you saw me write about the Dometic VacuFlush system for head plumbing. Well I have changed my mind in favor of something simpler. Specifically, the Raritan SeaEra macerating toilet. Reason for decision: I would rather not deal with complex repairs of the VacuFlush in my old age! We have a Raritan head on the small boat and have never had a problem in 20 years. I am hoping the SeaEra will perform as well. We have one on order, should be here in a week or so.

More when it happens.

Prepping for Paint: Various Tasks

The big task this summer will be hull paint, if everything goes smoothly and weather cooperates. Numerous tasks for preparation:


Sacrificial Coat of Paint for the Deck


The original cracking gelcoat nonskid has been stripped off. This leaves the underlying laminate exposed to the sun/UV. One doesn't want to leave this exposed for long periods as the UV will breakdown and weaken the laminate. Probably not an issue on this boat given the thick laminate schedule, but I just assume avoid it. The solution is a single sacrificial coat of white paint. Just a basic exterior enamel. This will provide protection from UV until we are ready to finish the deck (maybe next spring). Then the paint will be sanded off as part of preparation. The white color also makes for a cooler deck in the summer, yet makes for slippery conditions when wet. Ultimate care is required when moving around on deck.




Caprail Material Failure Removal


A couple years ago, I installed a plastic teak substitute (PlasTeak) for the caprail. Now, it is an ultimate failure. While it installed easily and looked great, after a year of hot/cold cycles, the edges began to split where there was more than a slight bend. I had originally intended to paint around it, but the failure requires removal entirely. This will make painting all that much easier as I don't have to worry about taping the caprail.


As a result I have decided to glass over the hull/deck joint for strength and maximize resistance to water intrusion.


New Boarding Stairs


The original, narrow, weakening boarding stairs when up along the port side right against the hull blocking access to a large area. A new set of boarding stairs have been built at the stern, starboard side, with a landing where the upper section of the stairs can be pulled away from the boat to provide access to the hull surface. The new stairs are wider and sturdier and should well serve the remainder of this project. Removal of the old stairs will finally give me access to finish the port side deck drain which is still in a temporary state.


Removal of the old stairs will allow completion of the perimeter scaffold that gives easy access to the hull side during painting.

More later...

Deck Grinding, Repair, and Prep for Hull Paint

The thick old waffle pattern non-skid that was molded into the original gelcoat from the factory, has all been ground off. The vacuum attachment of the PaintShaver Pro tool, that was used for the grinding, collected %99 of the material. When emptying the shop-vac, I estimate twenty to thirty pounds of ground up gelcoat/fiberglass. That should make the boat faster, right?

Exposed laminate from non-skid removal


With the old white gelcoat removed, the fiberglass laminate was exposed to reveal numerous areas delamination from the plywood core. Some areas were quite large. Who knows how long these existed. But since the boat has been sitting for thirty years, the delmination is certainly not from stresses and strains on the boat. If anything the cause originates from the factory where the plywood core was not primed/prepped properly (to be fair, way back then in the 70s, boat builders just did not think, or even know of delamination problems).

The internal voids, created by the delamination, were repaired by strategically drilling holes in the deck down to the plywood core, at the site. Epoxy was then injected with a plastic syringe. In total about one to two quarts of epoxy was injected, which seems like a lot. The worst section was the cockpit floor where top of the entire removable rectangular section had separated from the core.
Clean(er) after thorough pressure wash.

Logistical conditions this summer are such that now is an ideal time to paint the hull. This will require a perimeter scaffold to quickly and easily move around the boat during the application process. It will also require removal and relocation of the original boarding stairs, which will finally give me access to properly finish the port side deck drain.

...that is somewhat hacked, but should suffice.

Goodbye Nonskid

Finished grinding off the thick "waffle pattern" nonskid from the deck. Much of the delamination on the cabin top has been repaired. There are a few silver dollar size spots but I am not sure it is worth the work to fill those.

But with the non skid now stripped from the side decks, larger areas of delamination have appeared. I will be spending the next week filling in those 'new' areas.

The plan is to install one of the fake teak decking material. With the non skid removed, the revealed darkened laminate sorta gives an idea of what that deck material would look like.
