About the FORMOSA 41
Also known as the YANKEE CLIPPER 41. ATLANTIC CLIPPER. Similar to CT-41, SEA WOLF 40, SEA TIGER 41.
Designed by William Garden and built by Formosa Boat Yard Ta Chiao, the Formosa 41 is a robust, heavy-displacement ketch from 1972. With a displacement of 28000.0 lb and a full/long keel, this vessel prioritizes stability and seakeeping over speed, featuring a masthead ketch rig and a comfort ratio of 44.75.
- Best for:
- This boat is best suited for serious bluewater cruisers who value safety, stability, and traditional sailing characteristics, particularly those willing to undertake significant maintenance on aging systems. It appeals to owners seeking a proven offshore platform with a low capsize ratio of 1.61, rather than those prioritizing light-air performance or low-draft coastal access.
- Bluewater capability:
- The Formosa 41 is highly capable offshore, evidenced by its high displacement of 28000.0 lb, low capsize ratio of 1.61, and full/long keel design, which provide exceptional stability and motion comfort in heavy seas.
- Comparables:
- Comparable boats include the Hallberg-Rassy 41 and the O'Day 42, as they share similar heavy displacement, full-keel designs, and ketch or sloop configurations from the early 1970s. These vessels offer similar offshore capabilities and traditional layouts, making them direct competitors in the used market for classic cruisers.
