Designed by Magnus Öster and Bo Jonsson and built by Gecco Marine (SWE) from 1980–1990, the Gecco 39 is a substantial cruising sloop with a displacement of 16534.0 lb and a beam of 11.88 ft. While the exact hulls built count is unknown, the fleet is characterized by a heavy, comfortable ride with a comfort ratio of 29.02, though owners report significant structural maintenance challenges.
- Best for:
- This boat suits experienced coastal cruisers and bluewater adventurers who prioritize comfort and stability over high-performance racing, provided they are prepared for rigorous structural maintenance.
- Bluewater capability:
- With a displacement of 16534.0 lb, a capsize ratio of 1.87, and a fin keel with 6.73 ft max draft, the Gecco 39 is well-suited for offshore passages, though structural integrity of the deck and keel must be verified.
- Comparables:
- Comparable to other heavy-displacement Scandinavian cruisers from the 1980s such as the Hallberg-Rassy 382 or Nautor's Swan 42, due to similar displacement, beam, and emphasis on offshore comfort.
