The transom skirt, and steam-bending

I installed the transom skirt:


I decided that the forward sheerclamps were too stiff to successfully bend into place, so I decided to steam them first. I made a minimalist steam box from an empty paint can and seven feet of “spa vacuum hose” from Lowe’s. For a heat source, I naturally used the same LP gas burner I got for the lead-melting. After an hour of steaming, each sheerclamp bent easily, and I clamped them to the outside of the hull to dry out for a few days.

Installing the footwell and main deck

Below is a shot of the centerboard pendant sheave, safely tucked away in the trunk. I 3D-printed the spacers on either side of the sheave.

Finishing and installing the floorboards

I have been finishing the floorboards with Danish Oil. It is slow work. Because the stuff is stinky I have to work in the cold garage, so the Oil needs a long time to dry. So far about half of the floorboards are installed, and the rest need one more coat of Danish Oil.

I also finished the centerboard trunk with several coats of clear water-based polyurethane. People will be able to look at it and know for sure that this is a wooden boat!

Painting the interior

To avoid poisoning everybody in the house, I used water-based paints from System Three: their epoxy primer and polyurethane topcoat.

The primer was nice to use: it goes on smoothly, and is easy to sand if you do it within 12 hours after application. Your tools clean up easily with water, and it doesn’t smell bad.

The top coat was much trickier, and there was a learning curve – I did reduce it the first coat, which ended up blotchy and lumpy. For the subsequent coats I reduced it about 12% with water, and the job went more smoothly. But it took 4 coats to get full coverage in the important areas of the cabin. The bilges are still blotchy, but nobody will ever see them. At least the stuff is mostly odorless (about the same as household latex paint) and it dries quickly – you can recoat after 4 hours, and it’s quite hard after 8 hours.

I’m glad to finally be done with all the fiberglass, epoxy, and paint work for the cabin and bilges.

Lots of sanding

I have to sand all the edges and bumps out of the fiberglass on the bottom of the hull. After that, it will get one more coat of epoxy, and it will have to be sanded again!

Got the floorboards fitted

I marked and cut one side, then used each cut piece as a pattern to cut the other side.

Some trivia for other builders: I needed 134 screws: all 1-1/2″, except for two in the outside rear corners that are 1-1/4″. I used flat-head Frearson bronze screws, with the heads slightly countersunk below the surface.

As soon as all the floorboards fit nicely and the screw holes were drilled, I removed them and set them aside to start work on finishing the interior.

Doing the floorboards

Lots of cutting, planing, and drilling screw holes. I 3d-printed some handy jigs to get the floorboards properly spaced and the screw holes nicely aligned.

Yay! Finished glassing the interior

The last portion to be glassed was the bow compartment, which is a hassle to reach.

Notice that for the forward compartments, I marked up the fiberglass cloth with a Sharpie to help me cut it out and position it. Nobody will ever see it after the boat is finished.

Filleting the joints

This is a time-consuming step. First, I pulled out all the wires. Then I started applying nice rounded fillets of epoxy paste to all the joints. I am about 2/3 done, and it will probably take about 30 batches of epoxy (one patch mostly fills a 12-ounce plastic cup).

I also added a few cleats to the floors and bulkheads that I hadn’t glued in place before assembly.

Tack-welding the hull parts together

I have been applying epoxy to all the joints in the hull. When it cures, I can remove the wire stitches that were temporarily holding them together. It has taken three sessions of gluing to do this. The bow was tricky, because the joints are hard to reach, and the sharp bends in the plywood mean that the gluing has to be strong.

This part was messy!
These joints were glued the previous day, so I have removed the wire stitches
