Attached the final 3 bottom panels to our Super Sailfish. We used TotalBoat THIXO (thickened epoxy) in the seam, ran a bead around the sides and keel, and another bead on the edge of the panel, that should help ensure complete coverage. One bead down one glueing surface is not enough, as the wood soaks in some of the epoxy and might result in a glue starved joint. When the panel goes on we look for a small bit of epoxy to squeeze out, that tells us the joint is full and there is enough pressure on the panel. It took about one tube of THIXO per panel. I like the THIXO because the consistency is perfect for this application, and it is handy to dispense it from the tube in a nice bead, that minimizes epoxy being smeared everywhere and optimizes keeping epoxy in the joint.
Once the panel was positioned we drilled pilot holes and fastened it with 7/8th inch #14 silicone bronze ring shank nails, supplied by Jamestown Distributors.
Keel strip fastened by drilling a pilot hole and counterbore for a 1 1/2 inch #8 silicone bronze wood screw with a Fuller combination bit. These screws use a Forstner bit. Screws and Fuller bit set also supplied by Jamestown Distributors.
Took a break between panels to see if we could trim the bottom panel with a flush blade on a DeWalt oscillating multitool. We could get close if we were careful. Sanded with 60 grit on a random orbital sander.
Back to drilling pilot holes for the nails, the template we made worked out great on the straight sections of the hull.
When we got to the curves at the bow we found it best to offset the template from the nailing line and use it as reference for the holes, otherwise we couldn't follow the curve.
I was told that only the Great Spirit can make something perfect, so goof ups are welcome on our boats. I made sure there were several, as tribute. And it gives the Usual Visitors something to look for.
Spacing for the keel strip screws was 6 inches, shhhh, don't tell anyone that Alcort recommends 7.
There is a 18 inch keel band that attaches at the bow, it is a continuation of a tab on the bow handle. We need to buy some more quarter oval strip to make on for ZSA ZSA, the one shown belongs to CHIP. While we are here, check out the keel strip or skeg. ZSA ZSA had a deep skeg that fit between the bottom panels, the Sunfish CHIP had a short skeg that covered the panel edges. I asked Skipper for guidance on how to make the new skeg, she said keep it tall and add the overlap, and call it the "Hunter Skeg" after her sailing ancestor LT. Ben Hunter. The Sailfish does not have much draft to aid in lateral resistance, the skeg should help with that and aid in tacking.
All 4 panels epoxied and nailed. Hunter Skeg fastened. 2 boards over the scarf joints to hold light pressure while the epoxy cures.
