I’ve learned quite a bit about boat building since joining the crew (although not enough to want to try to build one myself!) In order to squeeze planks together a 2×4 is clamped to the rib just above the newly installed plank and a wedge is pounded in to push the steamed and softened plank down against her sister. The 2×4 piece is tightly clamped, with 2 clamps, to the rib and the plank is clamped and pounded down.
Now that the planks are above the water-line they need to be “prettied up” so they are presentable to the viewing public and our Chalupa’s fans. The are planed to a graceful curve on the outer side.
