Design and Construction
The Comet 910 measures 29 feet 10 inches, with a 22-foot waterline and a 10-foot beam. Its length-to-beam ratio of 2.97 puts it on the narrow side. Displacement is 8,200 pounds, while a 32 percent ballast ratio and iron fin keel give the boat a settled, predictable profile underfoot.
The fin keel draws roughly 5.6 feet, depending on load. Period observers noted that this was shallow enough to fit into most marinas without drama. Wetted surface is about 301 square feet, and an immersion rate of 1,044 pounds per inch means the Comet sits heavily for its size—a consequence of carrying its 8,200-pound displacement on a 22-foot waterline.
Rig and Handling
The masthead-sloop rig carries 395 square feet of sail area. Against an 8,200-pound displacement, that produces a sail-area-to-displacement ratio of 15.54, suggesting lively performance in a breeze without being extreme.
The fin keel and skeg-hung rudder are typical of Finot’s work from this period. A capsize screening value of 1.99 and comfort ratio of 24.1 place the Comet 910 firmly in the coastal-cruiser bracket rather than the offshore-expedition class. Taken together, the numbers describe a boat that responds to careful sail trim rather than relying on brute stability.
Accommodation
Below deck, the Comet 910 has six berths. That count suggests a saloon plus forward or aft sleeping spaces arranged for a small crew or a family weekend. It also confirms that the boat was conceived as a camp-cruiser rather than a daysailer with a single pipe berth. Beyond the berth count, however, no other interior facts are verified here.
Known Issues
The iron keel is the only construction material flagged as worthy of note. Iron is prone to rust wherever its protective coating has been compromised. Buyers should therefore expect to inspect the coating and the keel-to-hull joint on any example offered for sale.
The Verdict
The Comet 910 is a small, straightforward Finot-designed cruiser-racer from the early 1970s. Built in meaningful numbers by Comar Yachts, it combines a relatively narrow hull, moderate ballast, and a marina-friendly draft. It’s a coherent coastal design with a verified six-berth interior and a sail plan suited to both club racing and weekends at anchor.
Pros
- Fin keel draws about 5.6 ft, allowing easy marina access
- Six berths in a sub-30-foot hull
- Solid fibreglass hull
- Designed by Groupe Finot and built by Comar Yachts
Cons
- Iron keel is susceptible to coating loss and rust
- Ratios point to a coastal cruiser, not an offshore voyager
- Berth count is the only verified interior detail
