About the COMET 910
The first boat from this builder to be called a COMET, and one of it's most successful. Including all the different versions, it is thought that nearly 1000 were built.
The Comet 910 is a compact, performance-oriented cruiser designed by Van De Stadt/Finot and built by Comar Yachts (ITA) between 1971 and 1987, with a total production of 491 hulls. Its design emphasizes a favorable sail area-to-displacement ratio of 15.59, making it a lively sailer within its 29.86 ft LOA footprint.
- Best for:
- This boat suits coastal cruisers and weekend racers who prioritize sailing performance and agility over heavy offshore comfort, particularly those seeking a manageable masthead sloop with a 10.04 ft beam.
- Bluewater capability:
- With a capsize ratio of 1.99 and a displacement of 8200.0 lb, the Comet 910 is generally considered suitable for protected coastal waters and short offshore passages rather than extended bluewater voyaging.
- Comparables:
- Comparable boats include the O'Day 28 and Pearson 28, as they share similar production eras, displacement ranges around 8200.0 lb, and roles as popular, accessible coastal cruising sloops.
