As is the case with his smaller beach tri, building plans are also available for this sailboat. (They’re not pricey either)!
About this larger, 21-footer, Matt writes an ample description, which includes the following:
“The main hull (vaka) is multi-chined with a narrow flat bottom, graceful stem profile, and vertical stern to carry the kick-up rudder. The boat is built of marine plywood over a light spruce frame. The topsides are ¼” (6mm) while the bottom and decks are 3/8” (9mm). The main hull features a small cuddy cabin forward, a storage compartment aft, and a self-bailing center cockpit.”
With his permission are a couple Comet 21 pics (see more on his webpage)…
As you can see for yourself, the amas on this boat are very Newick-esque. See Matt’s design bio here.
