LONGIDIENUS 39′ outboard cruiser

The power cruiser LONGIDIENUS is long, lean, and light—and trailerable.

Power cruiser LONGIDIENUS


The warped V bottom has a fine, deep entry that is buoyant and slices through waves. Flat sections aft minimize drag at slow speeds and reduce rolling. The hull is built of fiberglass-sheathed okoume plywood on plywood bulkheads and spruce stringers. The wheelhouse contains the helm and galley, and offers a 360-degree view. The head, hanging locker, and V-berth are forward of this, and the cockpit is aft. Featured in the Sketchbook department of WoodenBoat magazine No. 282 (September/October 2021).
