Oysta 25

Designed by Sam Devlin

A 25 ft double-ended motorsailer idea from Sam Devlin, styled after the short North Sea fishing boats, with an 8 ft 6 in beam and 3 ft draft. The shop once built a hull to this concept for a customer, and the page describes it as a very seaworthy, compact little cruiser. It is the smallest of the Oysta motorsailer family, which runs up to 62 ft.

Only downloadable study plans are sold, so a builder would need Devlin to develop construction drawings before starting. The heavy double-ended form and a full cruising interior point to an experienced amateur. As a rule of thumb for a boat of this type, expect 2,000 to 3,500 hours. Measured medians from build logs appear below.
