Hull & deck

Deck painting & hatches

Fourteen weeks of sanding, priming and painting, new hatches and companionway.

The deck had 40-year-old paint, "maintainable", as I wrote before buying her. That word did a lot of work. In the spring of 2024 I finally repainted it: 130 hours, 19 work days, 14 weeks. Before that came the companionway and the new hatches, and after that a deck that looks better than new.

Companionway slides and boards

Day 22–3323 Apr – 2 Nov 2022

In April 2022 I made new companionway slides: a dry fit and a temporary install, the front edges cut at the right angle, teak oil still to go. Looks cool. I drilled the mounting holes from inside and put threaded inserts for M6 bolts into the wood, so the rails screw on from INSIDE, with no extra holes in the deck.

In May the new companionway boards were made and installed: the top board repaired, and two new ones made from teak, with 1/4-inch acrylic windows. And the deck drains I had epoxied were still leaking. Sanding showed voids in my "caulking", so I sanded out the extra goo, worked like a dentist to open every void, and filled them with flexible epoxy, so the joint is one solid piece.

In June I re-bedded the companionway slides properly, since it was clear the deck painting wouldn't happen before October or November. (Spoiler: it happened two years later.)

November 2022: one morning I felt water dripping on my head. The main cabin hatch frame had been sealed with silicone, and of course it had failed. I took all the planks off, cleaned and resurfaced them, and set everything back on 3M 4000 UV. The corners were a bit of a challenge. Three hours, and one less thing to fix later.

Hatches that didn't fit

Day 120–12918 Jan – 17 Feb 2024

January 2024: hatches, or how a small two-hour project quickly grows into a medium one. I decided to replace the original hatches, ugly, leaking, badly built and catching the jib sheets, with low-profile aluminum ones. Here's the original one.

It took almost three months to get the new ones: go2marine shipped one and back-ordered the second. Then I bought 4000 UV and butyl, and... found that round doesn't fit in square. The deck opening is square and the hatch frame has round corners, and the frame is about 8 mm smaller than the opening on each side. That's good (the other way would be bad), but together it means the corners turn into holes. Here are the views from inside and outside. So: a fiberglass frame, patching, sanding, painting, and a couple of days of waiting. Step one: sand off the gelcoat where the glass goes. Then plan the frame. I couldn't leave the opening open, so the old hatch went back on, sealed as well as I could.

The trap was this: a guy in a Facebook group had recommended this model as a direct fit. Maybe his IC34 was built differently, but I got trapped. On MY boat the deck openings were just square cuts. When I dry-fit the brand new, shiny hatches, their rounded corners didn't cover the square corners of the openings. And the hatch was about 3/4 inch smaller than the opening, so the mounting holes landed EXACTLY on the edge of the deck.

So I needed adapter frames, to cover the corners and give the screws something to bite. After a week of thinking I chose G10 fiberglass plate, 16 mm thick, with a lip that lies on top of the deck. The outside matches the old deck opening, and the inside matches the hatch.

But cutting each frame from one solid 16 mm sheet would cost about $300 per hatch, and 80% of the sheet would be thrown away. Way too much. Instead I bought two 500 x 300 x 4 mm sheets, for under $80 in total, and laminated each frame from four layers. $80 instead of $600. Easy to say, harder to do.

The first layer is 5 mm wider than the opening and sits in a little groove I routed on the deck. The second is exactly the width of the opening and goes inside. The third and fourth are just side plates, not over the corners, for strength and so I can put screws in from inside if I need to.

It took several hours of planning, design and playing with my CNC. To save material, the top two layers are made of four pieces each, two with sides and rounded corners and two just sides, joined with jigsaw-puzzle ends. On the left are the frame parts, on the right the leftovers. Maybe nice mixing sticks.

The second layer goes on turned 90°, so the joints don't overlap. 4 mm holes keep the layers aligned and hold the small parts during machining, and M4 screws pressed the layers together for the dry fit and the lamination. It fits exactly. Then it was laminated, the nuts came off, and the screw ends were cut. ADAPTER FRAMES READY.

Then the deck. I had to take a little off the edge of the opening so the adapter sits flush, and fix the uneven surface: the deck corners were about 3 mm high. I cut a template from 3/4-inch MDF, 1 mm bigger than the top layer of the frame. It didn't fit my CNC in one piece, so it's two pieces glued together. Then a hand router with a template bit. REALLY DUSTY. Full body protection. The template was just screwed to the deck in two corners, to keep it flat as a reference. I found some voids in the original laminate and filled them with thickened epoxy.

By the way, I took all the gelcoat off around the hatch. In places it was 3–4 mm thick, and sanding took forever. I don't know how the pros peel gelcoat, but a small hand router with a 3/4-inch carbide bit, set to stick out about 0.5 mm, works great. Much easier than sanding: the whole area in under a minute. You have to be VERY careful and stop as soon as you see fiberglass, then finish with an orbital sander. And the bit won't be good for woodworking after that. Then one more dry fit with the real hatch, before gluing everything.

Eleven steps to a hatch

Day 126–20417 Feb 2024 – 22 Jun 2025

Step 3: the frames set on thickened epoxy.

Step 4: the whole surface glassed over with a layer of 1708.

Step 5: a flat base. I covered the surface with epoxy thickened with 410 microlight and pressed a 2x2-foot MDF board covered in freezer paper on top, with sand bags. When the "mold" came off, it wasn't pretty: air bubbles, paper wrinkles. But it's a good flat reference plane.

Step 6: I sanded the voids a bit and filled them with the same mix. Ready for primer.

Steps 7 and 8: two coats of Interlux Pre-Kote. The first had orange peel, so lots of sanding and a mandatory second coat.

Steps 9 and 10: paint. No picture before installing, sorry. It looks the same, just all white.

Step 11, the hatches, in sub-steps: dry-fit the frames, mark the holes, take the hatch out and drill for 10-24 machine screw threads, tap the threads, clean with 50% isopropyl alcohol, put butyl tape on the hatches, set them in and screw them down, vacuum the dust and pull out the brown paper plugs, and peel the protective film. The best sub-step is the last one.

After I slipped and almost fell on the companionway steps, I put non-skid stickers on the newly refinished steps. Better this way.

A year later, in June 2025, came another compromise. I meant to make trim frames to cover the gap between the ceiling trim and the hatches. Too many other things got in the way, and they're still not done. To trim it properly I'd need new frames around the hatch wells. So for now I just painted the rough fiberglass, so it's not so sore for the eyes. One coat in the picture; the second went on the next day.

Getting itchy

Day 13225 Feb 2024

In February 2024 I got itchy again and started the first step of the deck repaint: sand off all the flaking paint, gelcoat voids and damaged gelcoat. Two cockpit locker hatches were so damaged around the hinges that those areas need redoing. All the gray dots are gelcoat voids, some to patch, some to re-glass. And there were two places with minor structural damage. One looks like somebody hit the deck with an axe. There was also a sealant-filled drilled hole in the corner of the outside companionway step. Why it's there, I'll probably never know: the same mystery as the hole in the water tank. Here are the two "axe hits", big and small, ground out. And at the aft corner of the port cockpit wall there was some delamination, or maybe just a very "voidy" layup. I'll dig deeper before rebuilding it.

A plan with 20 steps

Day 1332 Mar 2024

March 2024. Paint prep sounds simple. The amount of work is enormous. My plan for every part of the deck, just 20 small steps for each square inch:

  • Go over every square inch of the cabin top, deck and hatches, and mark every crack, gelcoat void, stripped screw hole and drilled hole filled with sealant (I found several).
  • Grind every bad area to live fiberglass: voids, chips, stress cracks, delamination around cracks, slopes around unneeded and stripped holes, and the putty over the hull-to-deck screws on the transom, where the gelcoat cracks over the "plugs".
  • Glass over every void deeper than 3 mm (1708, my favorite), glass over the transom screws so they don't crack again, fill stripped holes under 5 mm with epoxy and 404, glass over anything bigger, and build up laminate over cracks.
  • Grind off sticking-out fibers and extra laminate.
  • Draft patching with TotalBoat TotalFair. Sand smooth, find what needs more fairing, fair again. Repeat until happy.
  • Sand everything so the new paint grips, degrease, mask everything that doesn't get paint.
  • Primer, sand, second primer, sand and clean until dust-free.
  • Two coats on the glossy areas.
  • Sand and mask the non-skid areas, first coat with non-skid grit, second coat.
  • Call friends and drink beer on the fresh deck.

I split the work into areas and started with the cockpit. At first I thought there'd be 5–10 small spots. In the end, just in the cockpit: about 20 small spots, 10–15 deep areas 3–10 mm deep, 3 places to rebuild the laminate because of deep cracks, and about 10 holes the previous owner had drilled in the top glass and never glassed. Here they are after the first glassing, three layers of 1708 each.

Then I ground off the fibers and did the first draft fairing with TotalFair. Sanding smooth: the blue marks show what needs more. And fairing again.

Every little void

Day 134–1359–21 Mar 2024

The cockpit got its final sanding. A few spots were still left, but it was 90% done. Next came the main deck, except the bow around the chain locker.

On the port side some spots had been sanded years ago and covered with a very aggressive tape. Getting that adhesive and the plastic leftovers off was really hard.

The companionway hatch cover came off. Almost all its screw holes were stripped. I tapered around them, injected West System with 404 and patched them. Later I'll drill new pilot holes and put the screws back. There were lots of small voids in the gelcoat.

On starboard, at the corner of the companionway hatch box, there was a stress crack: sanded to live glass and built back up with three layers of 1708, from small to big. Around the mast base, another stress crack opened up. There will probably be a full rebuild there when the boat goes to the coast, but for now I opened the gelcoat crack and filleted around the plate. Small voids everywhere.

Two spots on the toe rail had drilled holes just filled with sealant; they got sanded and re-glassed. I wonder what people mounted there. Another place with drilled holes was on the starboard cabin top. Several deep voids were re-glassed with 1708. And many more places needed attention, but no glass.

Then I sanded the deck after the patches and put epoxy putty on every imperfection: all the green dots. I also cleaned off some gelcoat over the old deck core repair that had never fully cured.

A new companionway hatch

Day 136–13724 Mar – 6 Apr 2024

The original companionway hatch was badly UV damaged: 27 x 29 inches of 1/2-inch acrylic. Finding someone to cut that size and charge only for what you get was a problem. 99.9% of suppliers sell only 48x96, 48x48, 48x24 or 24x24, and my hatch is just a bit over 24x24 both ways, so they push you to buy 48x48 and pay almost 4 times more: $450 instead of the $150 I paid. TAP Plastics cut exactly what I needed: Chemcast bronze acrylic, 47%. Here's the dry fit, and my drawing of the handle, to rebuild the original.

That day my wife came to help: she sanded the fairing with the random orbit sander, I hand-sanded the tight spots, and then I re-patched some places a second time. The next day, two more hours of sanding.

On the port side there's a small step in the deck, and rebuilding it was almost sculpture. I'm not sure why it's there, but it was a big challenge for Irwin's glass team to make it without voids, and they failed miserably. Most voids got West System with 404, then fairing compound, then sanding until the shape was acceptable to my eyes. After the second round only three places needed a third patch.

Then the final sanding: six hours with three different sanders, and hand sanding in the tight spots. I'd say painting a deck isn't easy; there are lots of tricky surfaces. I planned to prime at the end of the day, but by 5 PM I was completely exhausted, so I packed up and went home. The companionway hatch had no slides, so a bag of sand held it.

Primer problems

Day 138–1416 Apr – 6 May 2024

In April I spent a day wiping everything clean: first degreaser, then solvent, then primer. It's only about 400 square feet, but I did the wiping and the cabin top one day, and the cockpit and the area by the toe rails the next. Only the glossy areas get primer; the non-skid just needs washing with detergent, later.

There were two problems. Roll-and-tip left brush marks even with 25% solvent. And one coat of Pre-Kote doesn't cover well, so I needed a second. One more gallon of primer, one more day of sanding, one more day of priming.

Two weeks later came sanding between coats, wet this time. I don't know what went wrong, but the Pre-Kote didn't level, so there were deep brush marks everywhere, and lots to sand. The second mistake: waiting two weeks, so it got very hard. A couple of spots where I forgot to tip and just rolled were much easier to sand, so probably no more tipping on primer. After 10 hours of sanding I was close to ready. After washing off the dust I found about 10 spots for small putty touch-ups, done after work or at lunch during the week.

Then I sanded the second coat of primer. It looks better and better, but there's nothing to photograph. One more half day of wet sanding.

Painting under a tent

Day 142–14513 May 2024

Special thanks to my wife Maria for joining me for this last push on the cabin top and the deck.

Day one: sand the second coat of primer, and build a frame for a "painting tent", in case dusty wind or rain shows up.

Day two was almost perfect: about 25 °C, partly cloudy, light wind. We finished the tent and put on one coat of off-white Interlux Perfection, about 1.5 liters. The first full quart was mixed in one batch for the cabin top, the toe rails and the step outside the cockpit, then about 200 ml for the cockpit, then 200 ml again. We found that a thick foam roller works well: press firmly to lay the paint, then lightly to pop the bubbles and smooth it, IF the paint isn't thinned too much. At 24 °C I added only 15 ml of 2333N thinner per quart (1.5%), and it worked great. Here's me and the cockpit, first coat. And the big-big tent.

On day three the weather wasn't what I wished for: drizzle on and off, so the tent was very useful. The overcoat window is 8–48 hours, so it had to be Sunday or Monday, and Monday was a workday. So I painted on a not-great day, knowing the gloss might not be the best. For a deck, maybe not bad. In the morning we found drips on the transom top that had left matte marks, probably from light rain just after we left. I put another tarp over the back and duct-taped the gap between the tarps. Light sanding on the obvious runs, then the second coat. Four short words, but a lot of work over a 34-foot cabin, cockpit and deck. Hidden "Perfection". Light at the end of the tunnel. The cockpit is painted; the hatches came off to be done separately.

On day four there was a thunderstorm with showers at the lake, and I had left the companionway hatch open, with no cover on the tent roof. When I got there at about 6 PM there wasn't much water in the cabin, just enough for a T-shirt-sized rag. The paint had set before the rain, so the drips left no marks. I took the tarp off the transom for air and pulled most of the masking tape while the paint was set but not fully hard. The transom top still showed the drips from the first coat. It's a very visible spot, and I want it excellent, so it'll get sanded and repainted. Here are the port side, the starboard side, the shiny cockpit, and the view from the bow.

KiwiGrip

Day 146–14919–27 May 2024

Just a nice picture: the cover is open, the glossy parts look great, and it's on to the non-skid. During the week a couple of thunderstorms tore the cover in places. Maybe it was too hot for the boat under the tent, and she threw off the blanket.

I put the companionway wood parts back on butyl tape, and at the garage I patched, double-primed, sanded and painted the first coat of Perfection on the hatches.

Then came the non-skid prep, with the tent sides rolled up for some air. I sanded the cabin top non-skid to cut the diamond peaks down to about half, cleaned everything, masked, cut radius corners where needed, and scuffed the surface right next to the tape.

Day 147: KiwiGrip on the cabin top. It looks good. The cockpit is ready to paint.

Day 148: tape off, hatches and covers back. The cabin top looks great. The cockpit painting is done (masking tape keeps the hatches closed). I added one thing to the original non-skid pattern: a pad on the top of the transom. It was slippery climbing back aboard.

Day 149: the deck sides. Sanding, surfacing, masking. Lots of sweating: 28 °C and 98% humidity in the early morning, 34 °C and 80% toward noon. Too humid to paint, but the deck is ready for non-skid.

Done

Day 150–1552 Jun – 1 Jul 2024

June 2024: after 130 hours of work, 19 work days, over 14 weeks, the deck painting is officially done. The picture of the day. The bow is left unfinished, because the windlass goes in later this year. Besides that, the deck is sparkling new.

The pushpit rails and cleats went back on.

All the cockpit hardware is back. Ready to sail; I just need to sort the lines. I refitted the bimini canvas and put the bimini back. The cockpit waits for crew. I also sealed the gap between the companionway trim and the fiberglass.

Then the new companionway hatch went in: a new teak handle, 12 mm acrylic, and stoppers. The freshly refinished cover is sealed and screwed down. What's different from the original: new acrylic instead of the one ruined by 40 years of UV, and HDPE blocks top and bottom instead of the wooden stops inside the cover. Now the cover can't be pulled all the way out and go overboard, and the stops won't rot in the damp space under the cover.

And in July I made an inside handle for it, which does three jobs: a handle to slide the hatch from inside, a hasp for a padlock on the washboards, and a stop that leaves room for fingers. It's a small piece of teak with two holes for the padlock shackle, held by two #8 wood screws from outside, a machine screw from inside, and a 1/4-inch machine screw into a tapped hole in the lid from below, for some security. The screw end is flush with the top, so you can't grab it from outside, and there's super glue in the thread. The lock idea: a padlock with a detachable shackle. Put the shackle in from inside, with the free ends out, push it through two holes in the upper washboard, and put the lock body on. Here's the view from the cabin, and from outside.

Fourteen weeks of sanding, patching and painting, and Vira's deck finally looks like the boat I see in my head. And the last step of my plan, calling friends to drink beer on the fresh deck, is the easiest of all twenty.
