Marshall Sanderling 18'
Description
The Marshall Sanderling 18 (often just called the Sanderling) is a classic American catboat—a traditional, single-sail gaff-rigged design—built by Marshall Marine Corporation in South Dartmouth, Massachusetts. Introduced in 1962, it's one of the longest continuously produced fiberglass sailboats, with over 860 built to date. Designed by Breckenridge (Breck) Marshall as a modern take on a 1941 wooden catboat by "Pop" Arnold, it revived interest in catboats by making them accessible, durable, and practical in fiberglass rather than wood. It's renowned for its simplicity, stability, spacious cockpit (unusually large for its length), and versatility as a daysailer with overnight/weekend capability. The design emphasizes ease of handling—great for solo sailing, family outings, or shallow-water gunkholing—while offering surprising performance, especially downwind where its big sail area shines.
