Compumarine Classic Dingy (Sloop Rig)
Description
Compumarine is a small craft design studio founded by John R. Clark (also known as John T. Clark) in Rio Rico, Arizona, USA, operating since 1989. It specializes in cedar strip-planked (bead-and-cove or butt-joined) wooden boat plans for amateur boatbuilders, focusing on lightweight, elegant dinghies, tenders, skiffs, canoes, and fishing boats suitable for rowing, sailing, paddling, or small outboard motors. Compumarine emphasizes traditional aesthetics combined with practical performance (e.g., low wake, good stability, and easy handling as yacht tenders), with plans including full-size patterns, comprehensive construction manuals with photos/step-by-step instructions, and options for epoxy/fiberglass sheathing. Thousands of plan sets have been sold worldwide, with many featured in WoodenBoat magazine launchings and forums like WoodenBoat Forum and BoatDesign.net. The company website (compumarine.com) appears archived or inactive in recent years, but plans remain available via secondary sources (e.g., archived PDFs, eBooks on Amazon, or direct contact). Outstanding features across designs include cedar strip construction for beautiful, varnished finishes, wineglass transoms on many models, lightweight yet strong hulls (often 45–150 lb dry), excellent rowing/sailing characteristics, and versatility as family projects or tenders.

Disclaimer. Boats are not all the same -- even when produced in the same factory of the same model. Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
