Comar Comet 850 Buyer's Guide
The Comar Comet 850 is a late-seventies Jean-Marie Finot design built by Comar Yachts in Italy, with several hundred examples afloat. A 28-foot fiberglass cabin cruiser with a masthead sloop rig, it remains a compact, six-berth cruiser for shoppers comparing classic Finot-era boats on the used market.
Layouts on the Used Market
The standard layout carries two cabins, one head, and six berths within the 8.50-meter hull and 2.90-meter beam. Both hull and deck are fiberglass, with a fixed iron fin keel and a shaft-drive Nanni Faryman 12 cv two-cylinder diesel. Two draft versions exist — about 130 cm and 160 cm — so a buyer should confirm which keel the specific boat carries, as it changes marina access and grounding posture.
Equipment and Common Upgrades
The period fit centers on a Nanni Faryman diesel with shaft drive and a masthead sloop rig carrying a 42.50 square meter sail plan. Rigging sizes are consistent across examples: 22.4-meter halyards at 8 mm and 10 mm sheets for genoa and mainsheet. Buyers should focus on the mechanical and sail-handling core — engine, shaft, and standing rigging — rather than treat period electronics or comfort add-ons as decisive.
What to Inspect
Owners report water collecting in the port aft locker where the diesel tank is located, so check that locker for ingress and tank corrosion. Period owner accounts also mention a cockpit communicating with the outside under the helm; examine this opening for sealing and any unintended drainage path into the hull. Verify the actual draft against the 130 cm or 160 cm version recorded for the design.
Availability and Buyer's Takeaway
Shoppers will find the boat where Finot-era Italian cruisers trade. For a used Comet 850, confirm the diesel locker and cockpit sealing, match the keel draft to your waters, and assess the shaft drive and rigging. Short checklist: port aft diesel locker dryness, cockpit-to-outside helm seal, draft version, engine and shaft condition, rigging wear.
