Designed by Ted Hood and built by Bristol Yachts Inc. (USA) from 1970–1986, the Bristol 40 is a robust, heavy-displacement cruising sloop with 149 hulls produced. Its reputation for solid construction is tempered by widespread owner reports of critical structural issues, particularly regarding the rudder assembly and deck core integrity.
- Best for:
- This boat suits experienced coastal cruisers and bluewater adventurers who prioritize seaworthiness and comfort, provided they are prepared for significant mechanical and structural maintenance. It is well-regarded for its stable, motion-comfortable ride, making it suitable for couples or families seeking a capable offshore passage maker.
- Bluewater capability:
- With a displacement of 17580.0 lb, a capsize ratio of 1.66, and a full/long keel, the Bristol 40 is inherently stable and well-suited for offshore passages, though its bluewater readiness depends heavily on addressing critical rudder and deck core vulnerabilities.
- Comparables:
- Comparable boats include the Cal 40 and O'Day 40, which share similar displacement and era, but the Bristol 40 distinguishes itself with a heavier build quality and full keel design. It also competes with the Hallberg-Rassy 42 for those seeking a similarly robust, traditional cruising platform, though the Bristol offers a more accessible price point.
