The hull consists of an outer gelcoat layer in your choice of 12 brilliant colors and laid up fiberglass cloth. Amidships carbon-fiber banding reinforces the keelson. Using epoxy instead of CA prevents hard points being visible from outside the hull. I began by assembling the keel fin to the lead bulb. The clear instructions easily allowed me to set the bulb at an 87-degree angle with the fin.
Fillets reduce underwater drag.
After you have attached the keelson block, you must decide whether you want a removable fin and bulb. Some builders prefer the ease of transportation and storage of a removable fin, but I think it is more trouble than it's worth. If you opt for the removable fin, coat the fin bolts with a light coat of oil or grease before you slip the bolts through the holes in the hull and the keelson block. To ensure a good seal, apply a thin layer of epoxy to the top edge of the fin and the keel bolts before you tighten the nuts that hold the fin in place. To ensure that the fin is perpendicular to the hull, suspend the hull between two padded chair backs and level the hull with a spirit level.
