Plank on Frame
Plank on frame construction is what many people think of when they think of classic wooden runabouts. The bottom is generally two layers of wood, both mahogany planking in the case of original construction, screwed to the boat's frames. One newer method of restoration which we use is a first layer of diagonally cut marine plywood attached to the frames and sealed with 3M 5200 followed by a second layer of mahogany planks bedded to the plywood with 3M 5200. This produces a watertight bottom which still can contract and swell with the elements.
