Last October I introduced my current project—turning a 1983 Herreshoff America catboat into a pocket motor cruiser.

It was time to start building the boat up into the classic looking motorboat I had in mind.

Progress has been painfully slow. There’s simply been more fussy details to work through than I estimated. The first step was to turn the hole I sawed in the cockpit sole and transom into a watertight and sturdy motor well. The well is built with 3/4-inch Okoume plywood screwed, epoxied and glassed to wood stringers cut from 5/4 mahogany, all of it well bonded to the hull.
