Design and Construction
The Comet 51S is produced by Comar Yachts and carries the hand of designer Andrea Vallicelli, with a fiberglass hull that anchors its construction pedigree the builder Comar Yachts produced the 51S. It is classified as a cabin cruiser intended for cruising and regatta use, a framing that explains its balanced proportions and sloop rig.
Rig and Handling
Rigged as a sloop, the Comet 51S pairs a 148 square meter sail area with a 13,000 kg displacement and a fixed keel drawing 2.90 meters, dimensions that place it firmly in the performance-cruiser bracket the sloop rig carries 148 m² sail area. A Yanmar 100 cv engine with Sdrive provides auxiliary power, supporting maneuvering when the wind is light or the berth is tight.
Accommodations
The standard accommodation version offers three cabins, two toilets, and eight berths, while the charter configuration expands to four cabins, two toilets, and ten berths the standard layout sleeps eight in three cabins. This flexibility lets the same hull serve private owners or the bareboat trade without structural change.
Known Issues
The supplied authority documents record no specific defects, structural weaknesses, or recurring owner complaints for the Comet 51S, leaving the ledger silent on known issues beyond its stated specification and equipment.
Refits and Ownership
No refit programs or ownership-cost notes appear in the source material; what is documented is the as-built equipment, including the Yanmar Sdrive installation and the two accommodation packages available from new.
The Verdict
The Comet 51S is a purpose-stated cruiser-regatta sloop from a named builder and designer, with clear accommodation options and a documented sail plan. Buyers and readers should note that the available record is specification-led rather than experience-led.
