I began the day’s work with the sander, smoothing the new fiberglass in the cockpit patches and the fairing compound I’d applied on the main decks and port sidedeck.
After I cleaned up, I used my patterns to cut new core for the small area on the coachroof and the small section of the starboard sidedeck. After final preparations to these areas, I installed the new core in epoxy adhesive, weighting it down securely.
Meanwhile, I cut the new core for the large section of the coachroof and for the bridgedeck, using the patterns I’d made earlier.
We planned to eliminate the deck prisms from the bridgedeck, and before I could install new core here I needed to patch the holes from above. This was a simple task since there was a nice flange beneath the existing rectangular openings, so all I had to do was clean up the faying surface a bit and install some 1/8″ thick prefab fiberglass sheeting over the openings with epoxy adhesive. Sometime later in the project, I’d patch the openings from inside, where the remainder of the finish work would be required.
The port sidedeck was ready for its new layer of fiberglass over the inner skin, and I installed this now in epoxy resin. I extended the new material to the gunwale over most of the area, tying the inner skin back to the hull and hull flange as it should be. At the forward end, where the previous repair had met the existing decks in a messy and ineffective way, I brought the new inner skin layer up and over the adjacent top deck (which I’d prepared expressly for this purpose) to help reintegrate the whole structure again. I didn’t worry about the short void in the old inner skin and just spanned it with the new material, which drooped slightly into the old void. I’d bring this up level once the first layer cured and I could build on top of it.
I went around the boat again with fairing compound, applying a second coat to the main deck areas as needed, and the initial coat to the cockpit patches.
It was a good time to start filling the stepped edge between the gunwale and the edge of the deck molding. In order to achieve the final profile I wanted for the new hull-deck edge, as well as to provide a smooth corner for the fiberglass, I needed to fill the 1/4″ or so high space with epoxy. With a very thick mix of epoxy compound, I worked my way down the port side and across the transom to the starboard quarter, filling this flat area and using a trowel to rough it in to approximate the shape of the hull and deck, bringing the shape as close as I could for the initial application. I’d hoped to finish up the starboard side as well, but with a pending appointment arrival I didn’t want to get caught in the middle of an epoxy pot, so I stopped a little early.

In the cockpit, I got started with the remaining top skin deck patches. After final cleanup, I used thickened epoxy to fill small voids and holes in the exposed plywood core, and wet out the core and surrounding areas. Then, I installed three layers of fiberglass in epoxy resin to complete the repairs. I left the area around the steering pedestal hole for later, as I still had to prepare and fill the large hole in the sole first.
Next, I made paper patterns of the deck sections to be recored: two areas on the coachroof and the bridgedeck, plus a small section of the starboard sidedeck outboard of the cockpit.
My plan for rebuilding the port sidedeck included starting with a new layer of fiberglass over the existing inner deck skin. This would help tie in the existing skin with the surrounding structures again, including the hull/deck flange, as well as provide a sound base for the new core and top laminate. To this end, I made patterns of the area that I used to cut new 1708 fabric in several pieces to fit. The new glass would extend from the inner edge of the old core, near the flange at the cabin trunk, all the way to the edge of the hull to tie the whole area together.
The existing inner deck skin and the transition at edge of the hull featured various voids, depressions, and rough edges, a combination of ills from previous repair efforts (including an inner skin that was tabbed to the inside of the hull below the original hull flange), damage subsequent to those repairs, and removal efforts.
To begin to prepare this deck for new work, fill low spots, and smooth out the transitions, I applied a coat of thickened epoxy to these areas. With a bit of unused fairing compound remaining at the end, I used it to start to smooth out the old damage in the port cockpit coaming so I could fully rebuild that area later.
On the main decks, I went around and sanded the new fiberglass patches I’d installed last time, bringing the edges smooth and flush with the existing decks as necessary. At the same time, I did an initial sanding of the nearby deck surfaces, which featured the original gelcoat and mild nonskid pattern. With substantial new work and plenty of fairing and sanding still to come, I didn’t make an effort to fully prepare the old decks at this time, as future work–including the fiberglassing for the hull/deck joint and the fairing to go along with it–and later sanding efforts would see me going over these areas again and again. Some areas of the original deck had numerous gelcoat voids that I’d have to take care of as well, but with the existing sanding I could now start to address these issues as I worked in nearby areas in the coming days and as surface preparations continued.
Afterwards, I cleaned up and applied a first coat of epoxy fairing compound to the main deck patches.

I finished up the patterning for the various top-skin deck repairs in the cockpit, following the same process I’d done on the main decks earlier.
I spent the rest of the morning cutting three layers of 1708 biaxial fabric for each patch.
During the afternoon, I began by filling various small voids and holes in the exposed plywood core with a thickened epoxy mixture, and also pre-wetting the core and surrounding areas with epoxy to prepare for the new laminate. For now I focused only on the main decks, leaving the cockpit for another session.
At each location on the main decks, I installed a layer of 1708 cut to fit directly over the core, bringing the center of each opening up roughly flush with the adjacent deck surfaces that I’d prepared earlier, and used additional slightly-thickened epoxy to smooth the edges for the next steps.
Finally, I installed two layers of the 1708 in epoxy resin over each section. The final layers overlapped the adjacent decks by a couple inches on all sides and tied the new work in with the existing laminate.

Picking up where I left off, I continued work on the hull/deck joint preparation, working my way past the starboard quarter and across the transom.
At the same time, I more thoroughly prepared an area on the port hull where some previous repair work had been, grinding out some suspect fairing compound and otherwise preparing the area for fiberglass reinforcement and refairing.
Though I’d been cleaning up incrementally throughout the week, the heavy sanding work had made a mess of the boat and shop, and while there’d be plenty more sanding to go as time went on, for the moment I was done and planned to focus on getting the decks put back together, so I spent some time giving the shop and boat a good cleanup. While I was at it, I went over the newly un-cored areas to ream out any final bits of core from beneath the deck edges and used an air nozzle to blow out the voids and help prepare these areas for new work. It was perfect timing for all this since for once the weather outside was door-worthy and pleasant for airing out the shop.
Later, I went around and made simple paper patterns of all the areas on the main decks that required relamination. As the simplest of the repairs to come, I chose to make these the first on the list; plus, having the main decks closed up again and sound would make it easier to work on the coachroof and other areas. The outside of the pattern represented the largest piece of new fiberglass, which would extend to the outer reaches of the prepared areas on the adjacent decks, and the marked regions int he centers of each pattern represented the size of the deck opening itself, as I thought I might start with a layer of fiberglass directly over the exposed core so the subsequent layers would end up more flush in the end.

On the port sidedeck, I ground off the gelcoat and otherwise prepared the remaining adjacent deck areas surrounding the large area where I’d removed the old core and previous repair work, and also ground out several large cracks in the cabin trunk and forward part of the cockpit coaming that had been patched with a thick, ungroomed gelcoat putty. In the same session, I prepared the remaining small repairs on the foredeck, grinding away the gelcoat and tapering the edges of some existing holes and other areas where I’d removed the top deck skins for repair.

During the remainder of the day, I worked my way around the boat to prepare the top of the hull and the edge of the deck for fiberglassing later, starting at the port quarter and sanding away the gelcoat to the marks I’d made earlier and cleaning up the deck edge as needed. As I worked past, I also used the sander to clean up the inner deck skin on the port sidedeck and other related surface prep in this apocalyptic area that called out for my attention now. By the end of the afternoon, I’d worked around the stem and back down the starboard side to the cockpit area, leaving the last bit of the starboard side and the transom area for next time.

With plans to reinforce and glass over the hull/deck joint, there was now no question that I needed to remove the bowsprit. I’d postponed this for various reasons, but never truly thought it would end up staying in place–there were always too many reasons to remove it, even if the existing platform was re-used. I proceeded carefully to as to save the platform without damage. With things about to get dirty and nasty in the shop with some major deck work ahead, now seemed the best time to take care of this removal.
The platform was secured through the foredeck with 11 bronze carriage bolts, including four through the inner forestay attachment point. Even before removal, I could see a thick bed of silicone sealant beneath the platform that promised to make removal challenging. Access to the bolts from the chainlocker was tight, as the opening into the chainlocker was not only small, but awkwardly placed thanks to a stepped section in the cabin liner that incorporated a little storage bin.
I removed all the nuts I could from belowdecks and hammered up the bolts so I could reach them from above, but the configuration of the access simply didn’t allow me the reach I needed for the forwardmost bolts. Fortunately, the way the bare platform had weathered over the years meant that the carriage bolt heads stood a bit proud of the adjacent surface, so I could easily cut the heads off with a saw without affecting the surrounding wood. Once I had all the nuts removed and/or heads cut off, I removed or pushed the studs back down through the holes and into the boat to free up the platform, other than the sealant.
Freeing the platform, which extended over the deck by several feet, all of which was heavily bedded in the silicone, was quite a chore, particularly while being conscious of keeping the platform intact. In increments I eventually managed to slowly pry up the platform, first from one side, then the other, and finally drove a chisel all the way beneath it near the stem, which helped finally start breaking the grip of the highly flexible, thick layer of rubber. To prevent the platform, which extended further outboard of the boat than over the deck, from pivoting off uncontrollably when I finally cut the last of the silicone, I ran a small line through the aftermost pair of bolt holes and tied the platform to the boat. Once I finally freed the platform, I could spin it around so it rested on the deck so I could regroup and then lower it down to the shop floor.
The platform was in basically good condition, with some damage at the outermost end on the underside, but heavily weathered. For now I could leave it be, as it would be some time before I needed to reinstall it.
With a chisel, and then a paint scraper, I removed the bulk of the old silicone from the foredeck. The layer was about 3/16″ thick over most of the deck.
Preparing for several days of heavy sanding work ahead, I made some reference marks on the hull and deck on either side of the gunwale to indicate how far to remove paint or gelcoat for the hull/deck reinforcement.
During the remainder of the day, I used a grinder to prepare the edges of all the areas to be recored and relaminated, removing gelcoat and creating a slightly tapered raw fiberglass edge over which the new work would eventually bond and tie in the repairs with the existing structure. I also cleaned up the inner deck skins and top of the original plywood core as needed. In this session, I completed the work on the starboard coachroof, bridgedeck, cockpit, starboard sidedeck, starboard foredeck, and poop deck., leaving the port sidedeck and other areas for next time.

The sharply curved coachroof was mostly covered with Treadmaster nonskid, a flexible sheet product with an aggressive pattern. The installation in this case was rather rough, with pieced-together sections and lack of attention to detail. In order to continue with the deck repairs and deck refinishing, I needed to remove this, not only because its appearance was poor, but the deck beneath–which had been repaired at some earlier time–was extremely roughly finished and uneven, and required additional work and refairing.
The nonskid sheets appeared to be installed with a flexible adhesive rather than epoxy or similarly aggressive adhesive, and this promised to make removal relatively possible, if unalterably tedious. During an earlier removal test, I’d found the Treadmaster relatively easy to scrape free with a chisel, but this was slow.
To get started, I tried the chisel method at the aft end of the coachroof, and made some progress, but I just couldn’t see doing the whole area (at this point it looked like a sports field in size) with a 1″ chisel. The adhesive, whatever it was (I thought probably a polysulfide) was not that aggressive, but was still resilient and flexible and, while at least possible to remove (unlike something like 5200 or epoxy), it wasn’t exactly a breeze either.
In an earlier project, I’d had pretty good success using a power planer to remove the Treadmaster. I’d held off trying it here because I had some dim memory of my planer being inoperable, though I couldn’t remember why, but I soon found that I’d been stymied changing the blades the last time (this was in 2010) because of a recalcitrant fastener holding one of the blades in place. Apparently I’d put the planer away and never used it since. Now, though, I discovered that I’d apparently purchased replacement parts for the screws at issue, so I was eventually able to use semi-destructive means to remove the fastener (I used a Dremel tool to cut a slot for a screwdriver, since the Allen screw head was stripped), after which I could complete the blade replacement with the new parts that I’d ordered before.
The planer worked quite well. Fortunately in this case the deck was all convex and wide open making it easier for the flat base of the planer to work; it doesn’t do so well on tight spaces and with different curvatures. This removed the bulk of the Treadmaster easily and pretty quickly, generating huge piles of debris. Once I got down to the flexible adhesive, I I found I couldn’t really use the planer any more, as the base bound on the rubbery surface and didn’t really allow planer movement, though the blades would cut through it if I could keep the planer moving.
To remove the rest of the adhesive, I turned to my 1″ chisel (I tried a larger one but it wasn’t as effective), and hand-scraped the bulk of the adhesive (which, thanks to the undulations in the deck beneath, was quite thick in many areas) and thin remnants of the nonskid material, much of which came off in stretchy sheets. This left just a bit of residue behind which I cleaned off with a carbide paint scraper, leaving a surface that I could finish up another time with a sander. The scraping steps were plenty of work, but it wasn’t that difficult to remove the adhesive cleanly.
In this three-step manner, I continued for the remainder of the day, eventually removing all the Treadmaster and virtually filling a large garbage can with the spoils. The planer blades were pretty dull by the end, but still managed to do the job I needed them to do, if a bit more slowly. I found as I went on that it was easier to leave a thin skim of the Treadmaster rather than fight through the top layer of adhesive, with no noticeable increase in difficulty for the scraping steps afterwards.
The deck beneath would require plenty of additional work to properly fair and finish, but despite that the glasswork had seemed sound throughout the process.

I had my trusted upholster make up a new filler cushion to fit in the required space, and with this now complete, along with the minor work I’d had to do on some of the trim pieces from last time, I made a quick trip to the boat to deliver the new cushion and finish up the installations.
I also finished up the trim on the nearby companionway. When the ladder unit is properly secured with the four thumbscrews that attach it to the structure beneath, the seam between the trims would become tight; for these photos, I just placed the ladder assembly in place loosely.

I wanted to extend the cutout on the port sidedeck a bit forward, into the original portion of the deck, to see what the transition area was like (between the previous repair and the original) and to better judge the condition of the coring immediately adjacent to the areas I’d removed before. In this area, I expected the core to stop well short of the deck edge roughly 7″ inboard, so I made my new cut accordingly.
Here, at least, the top skin was still adhered to the plywood core, and by the forward end of the cut the core was showing less in the way of water damage. Removing the plywood from this section revealed the transitional area, which had previously been at least moderately reinforced from below, but I’d have to reconstruct the bottom skin over the existing area to better repair and strengthen the new work. I’d tie this all in with the adjacent deck and hull as well.
Moving to the starboard coachroof, I began by cutting open an area inside the companionway rails, leading aft from the section of the deck that had been rebuilt at some time in the past. My initial cuts were a bit shy of running into sound core on the aft and inboard sides, so I expanded the area a bit till clean, dry core bordered the entire cutout. As expected, the balsa core in this area was in poor condition. I intentionally extended my cut a bit forward into the newer work to help me judge the condition of that area as well.
I removed the old core from the cutout, reaming it out of the slot on the outboard side near the companionway rail as much as possible. The core in the adjacent section was a foam product, probably Divinicell, and the good news was that at least in this small visible area, the core and top skin looked sound, belying the rough outward appearance of the deck itself.
Next I cut the top deck skin outboard of the companionway on this side, removing the entire section. The core within was in extremely poor condition.
Again, I extended the cut an inch or two into the foam-cored section just forward, giving me another place to judge the condition and to better integrate the two areas during repairs.
I removed all the coring from the newly-opened area, scraped up the worst of the residue left behind, and cleaned out the edges below the adjacent deck flanges as much as possible. It’s worth noting that even given the poor and deteriorated condition of the balsa here, much of the saturated wood was more strongly adhered to the skins on either side (upper or lower) than the plywood on the port deck that I’d removed last time.
During the deck inspection, I’d found any number of small areas on the foredeck, starboard deck, cockpit seats and well, and poop deck (all original construction) where there was a clear separation between the top skin and core beneath (debonding). Core sampling in most of the areas revealed clean, dry core (plywood). Now I went around and removed the skins from these areas so I could install new fiberglass that might have a chance of bonding with the core, as the original had not.
In most cases, when I removed the top skin (with virtually no effort),there was little or no sign of the core ever having been properly bonded to the skin, though in some areas I found small globs of whatever adhesive (resin-based) was used during the original construction to secure the plywood to the underside of the top skin, with virtually no contact between the core and the skin in other areas, so these voids were latent and had been there since the boat was first constructed.
In many areas, I found clean holes apparently drilled into the plywood coring, though for what purpose I couldn’t imagine. These were separate from the various test holes (and in some cases old fastener holes) that penetrated the core. The coring was sound in all areas, and was simply a normal grade of plywood. I’d rebuild all these areas with new epoxy top skins in due course.
Next, I turned to the wide bridgedeck, where I knew most of the core was in poor condition. At first, thinking the center section of the deck might be sound, I limited my cuts to the end sections, but eventually decided to remove the entire center section too, since the damage extended far enough in some areas that it just made sense.
I spent the rest of the day cleaning out the old core from this large section, including around the edges, and cleaning up the spoils from the day’s removals.

Armed with a hammer and drill, I went over all the deck areas to determine the overall condition of the structure and locate any areas requiring further inspection or repair work. I used the hammer to sound the decks, looking for indications of top-skin delamination or debonding, or wet and damaged core within.
The poop deck, leading up to the winch pads on each side, was generally sound on both sides, with some minor top-skin delamination noted around the new opening for the deck hatch and in other isolated areas. The core was 3/8″ plywood, and my test holes here and there showed no signs of core damage, other than normal and expected discoloration around some of the old fastener holes. As in other original parts of the deck structure, the edge of the deck was solid fiberglass for quite a few inches in board before the core began.
The condition of the port sidedeck had bee a concern since the moment I first saw it upon the boat’s arrival here, but there were many questions about it and even after various related work I still was unsure what was going on. Sounding tests were OK, but this wasn’t a big surprise since the top skin–which was part of a previous repair and not original–was extremely thick and resin-rich, as indicated through the old water tank fill hole, which I’d opened up earlier in the job.
I drilled numerous test holes along the length of this deck, and in each case the core spoils–plywood again–came up dark and damp. This was not a surprise, as I’d noted the wet core as soon as I removed the deck fill earlier, but even so I’d been hoping that perhaps the whole area wasn’t wet, though in my heart I knew it would be.
This area along the edge of the deck, where it joined the hull, caught my eye, though at the time I wasn’t sure what caused the visible cracking at the edge of the deck. I’d soon find out.
Portions of the foredeck on the port side showed signs of moisture in the (still plywood) core, though this part of the deck was original construction. Here, the solid part of the deck was nearly 7″ inboard from the edge, at least as an educated guess from measuring inside the boat through a couple of the old hardware openings in the molded cabin liner. I wanted to know how far in the core edge was in all areas so that if it came to core removal, I’d know where to begin my cuts.
I found some dark and wet core in one of the first test holes on the starboard sidedeck, aft in way of a stanchion base location, but moving forward I found clean and dry plywood core, though as in most areas of the deck there was sporadic small areas where the top skin either had never bonded to the core, or had come free over time–such latent defects were always an issue in vintage polyester construction, and even more so with plywood coring, but overall were little cause for concern.
The entire port side of the coachroof and most of the forward section had obviously been repaired in the past, and roughly so. Where these areas weren’t covered with Treadmaster, it was clear the deck surface was rough and poorly faired, and was clearly work more recent than original. Sounding results were fair over the area, and in the forward part of the boat the deck was cored with balsa, visible through the hatch opening and old solar vent location. In the other areas, however, and in way of the obvious repairs, the deck turned out to be cored with some sort of foam, as indicated by numerous test holes that I drilled. Despite the poor outward appearance and rough construction, I didn’t immediately find significant cause for concern in the largest area of the coachroof, though for the moment I reserved final judgement pending additional work and investigation as needed.
The small section of the starboard coachroof outboard of the companionway appeared to be original, and here the deck was soft and in all ways indicative of damaged core, all confirmed with sounding and test holes.
This short video attempts to show the debonding of the top skin from the damaged core within.
The area inside the companionway rails, just aft of where the previous repairs had occurred, also showed signs of being partially wet and soft, though the condition of the core samples improved as I moved aft.
The cockpit areas, other than the bridgedeck, seemed generally sound overall, with some areas showing stress cracking from top-skin delamination, mainly in the areas where people would have logically stepped into the cockpit (the forward parts of the seats) and into the well itself (the forward corner of the well, and aft of the old pedestal location). These areas were not of major concern and could be repaired with relative ease. The core material visible through the pedestal hole was sound and dry. There was some cracking around the locker lid location,s particularly to port (which had already been the recipient of some reinforcement in the past). This was mainly because of the way the hinges had been attached, the leverage on which had caused the screws to loosen and crack the fiberglass.
As a test, I spent a couple minutes with a chisel that happened to fall close to hand to see what the Treadmaster removal on the coachroof would be like. The material was held in place with a black sealant product, and though removal would be tedious, the bond was easily separated and the adhesive easy enough to scrape away, which was good since there was quite a lot to remove.
All in all, while I still had my internal questions about the previous repairs on the coachroof (despite no obvious signs of major issue during the core sampling), the deck condition was about what I’d expected, given that the bridgedeck condition and port sidedeck had been known issues from the first moment.
Now I needed to know what lay ahead for me with the port sidedeck. I was unsure of the overall construction, since it was all something done sometime after original construction of the boat, so I approached my investigation conservatively till I could get a grip on what was going on. Starting around the old water fill hole, which was an area that I’d be patching regardless, I cut a larger rectangle out of the deck top skin so I could see how easily the deck might come apart if needed. I avoided cutting too deeply or too extensively for now: this was exploratory surgery.
Removing the thick top skin–it was about 3/8″ of solid glass, clearly old-fashioned mat and roving in a dense resin-rich matrix–revealed the expected damp plywood core. The skin came up with relative ease and was not well bonded to the plywood at all.
This area in particular, now and a little later in the process, revealed some strange material that looked to have been used as a filler or adhesive. It was reminiscent of sandstone, or hard brown sugar, and was brittle and friable in texture. I thought it might be remnants of a putty made from resin and wood flour.
I wanted to see how far outboard the core in this area extended. All signs were that it was much closer to the deck edge than in the original parts of the boat, so I expanded my opening a bit to search for the edge, which finally turned out to be right at the inboard edge of the hull flange. I dug the core out of my still-small opening. Plywood can be much more difficult to remove than old balsa, but in this case, despite having to force my way through the laminations of the plywood–damp as it was it still had some integrity–there seemed to be virtually no bond between the core and the lower (or upper) skins of the deck.
Now with a better sense of things, I expanded my cuts forward, extending past an obvious demarcation in the deck where this weird repair had ended. Once I’d made the cuts through the top skin and into the core, the skin lifted right off with nearly no bonding to the core beneath. Similarly, the core separated from the inner skin whole and without effort: there was simply no bonding remaining.
Though I left–and intended to leave–a 2″ or so wide band of the top laminate along the deck edge, I found that this laminate was not bonded to the hull flange in any meaningful way: any bonding that might have once existed had failed. This left the remaining strip loose and floppy, and this lack of bonding is what had led to the crack that I’d observed earlier at the edge of this very area. Whoever did this repair in the past had also fiberglassed the deck to the hull from within (this is why the liner had been partially removed in the cabin, all the signs of which were obvious while I was working down there earlier, though I didn’t understand the whole process yet at that time). So the bottom skin was secure, and the hull was still supported without the top skin, so with little choice I cut away and removed the small flange I’d left from the top skin. It wouldn’t be any harder–and would be a lot stronger in the end–for me to rebuild the deck entirely, while also incorporating additional tabbing to the hull over the area.
Moving aft, I continued the dismantling in this way. At first I kept the sections small, but it became increasingly clear that there was just no bonding at all between the compoents, so I was able to remove the last section in one large piece.
The video is rough, since the work was the priority, but it shows how easily I could pull up this large section of skin once I started with a small chisel.
At the aft end, I extended the cut as far aft as I could, though here the cored area was original and much narrower overall.
There was a sort of elevation change in the bottom skin just aft of the water tank fill location. Overall the bottom skin was in good, sound condition and would tie in well with the repairs to come. The appearance of plywood grain on the bottom skin is just the remnants of the imprint of the core when first installed.
Though I’d approached this sidedeck with trepidation, in the end I felt much more positive. All the suspect old work was gone, and what remained would be something I could easily rebuild in a stronger and superior manner. It’s always the unknowns that are the worst. With the worst and ugliest section of the deck now opened up and ready for new work, I looked forward to getting on with it.
