Custom Design

We can custom-design a boat–either power or sail–to exactly match you requirements. Or perhaps you are interested in modifying an existing design. Either way, we can provide all the design expertise required.

Here is a sampling of our custom design work, not including the smaller skiffs and daysailers shown on our Stock Plans page. You can also see our Fall 2012 Newsletter for more information about CALIDRIS, POSTHASTE, and others.

A New Design: TUVA II

TUVA II is not (at least at this point) a finished design, but just a preliminary to a design that I would love to build for myself. The purpose would be for cruising the coast of Maine and further north in the summers, and heading south during the winters for the US East and Gulf coasts, and the Bahamas. She is a compilation of my musings during parts of such trips in a variety of other boats, so I am pretty sure of what I want this new one to be.

Sketches and more information are available at my blog on Please click to see the blog and learn more about this design ( is a membership website).
