About the ANDREWS 70
The Andrews 70 is a rare, large-displacement cruising sloop designed by Alan Andrews and built by Dencho Marine Inc. in the USA. With only 4 hulls constructed in 1994, this vessel represents a unique, low-production entry in the market, offering substantial volume and stability for its era.
- Best for:
- This boat is best suited for experienced coastal cruisers and those seeking a spacious, stable liveaboard platform, given its significant beam and displacement. Its size and systems complexity make it less ideal for single-handers or novice sailors without substantial support.
- Bluewater capability:
- With a displacement of 26300.0 lb and a capsize ratio of 2.02, the Andrews 70 exhibits strong inherent stability and motion comfort suitable for offshore passages. However, critical structural concerns regarding the keel and rudder assembly must be thoroughly resolved before considering serious bluewater use.
- Comparables:
- Comparable boats include the Swan 681 and the O'Day 68, which share similar production eras and large-displacement cruising roles. These vessels are comparable due to their focus on interior volume, heavy displacement comfort, and robust construction typical of late-1990s American and European builders.
