Jichi's hull is cold-molded from a jig. The longitudinal fir framework is reinforced with 1-by-2-inch battens with 1-inch Core-Cell foam between each batten. Three layers of diagonally planked ⅜-inch Okoume plywood with epoxy-encapsulated 1½-ounce fiberglass mat between each layer follow to complete the bottom. Hull sides are three layers of ¼-inch Okoume, with fiberglass and epoxy between each layer, making the structure totally glassed 100 percent inside and out. With a wet weight of 78,000 pounds, this is not a light boat, but with 10 people aboard, with fuel, fishing and cruising gear, the Caterpillars give it a top speed of nearly 45 knots (at 2,317 rpm, we saw 44.5 knots at 97 percent engine load). Custom Veem propellers and a modified-V running surface certainly figure into this performance.
