The Comet 910 stands as the definitive vessel that transformed Comar Yachts—then operating as Sipla—from a smallscale builder of fiberglass dinghies into a premier European shipyard. Launched in 1971, the 910 was the product of an unlikely but brilliant collaboration between the established Dutch master Van de Stadt and the innovative French designer JeanMarie Finot of Groupe Finot. This partnership resulted in a boat that challenged the design conventions of the early 1970s, prioritizing a generous beam and a sophisticated hull form that offered both competitive racing speed and surprising interior volume. With a production run spanning over fifteen years and nearly 1,000 units produced, the Comet 910 became one of Italy’s most successful seriesbuilt yachts, earning a reputation as a "giant killer" on the IOR racing circuit while remaining accessible enough for family coastal cruising.

The model evolved significantly during its lifespan, most notably with the introduction of the Comet 910 Plus. While the original 910 featured a more traditional transom, the Plus variant often incorporated an integrated swim platform or a slightly extended reverse transom, along with modernized interior appointments. The hull’s versatility allowed it to remain competitive for over a decade, a rarity in an era where design trends shifted rapidly.

Sailing Performance & Handling

The Comet 910 was designed during the height of the International Offshore Rule (IOR) era, which heavily influenced its "busty" midsection and pinched ends. However, unlike many IOR designs that became temperamental downwind, the 910 is widely praised for its balanced handling and sea-kindliness. According to archival records from Groupe Finot, the yacht was engineered to excel in light to moderate Mediterranean winds while maintaining enough stability to handle heavier Atlantic conditions.

With a displacement-to-length ratio that leans toward the moderate-heavy side by modern standards, the 910 tracks exceptionally well. Its deep fin keel and high ballast-to-displacement ratio (roughly 40%) provide a stiff, powerful feel when beating to windward. In its racing heyday, the 910 proved its mettle by winning its class in the Middle Sea Race, a testament to its ability to maintain high average speeds over long distances. Owners often report that the boat "punches above its weight," feeling more like a 32-foot vessel than a 30-foot one when navigating choppy seas.

Interior Comfort & Variations

For a 30-foot yacht designed in 1971, the Comet 910 was revolutionary in its use of internal space. By utilizing a wide beam and a high freeboard, the designers created an interior that felt significantly larger than its contemporaries, such as the early Arpege or Albin Ballad. The standard layout features a classic V-berth forward, a central salon with opposing settees that double as sea berths, and a functional galley and navigation station flanking the companionway.

The "Plus" versions and later production runs saw improvements in the quality of joinery and the ergonomics of the heads compartment. While early models focused on the utilitarian needs of a racing crew, later iterations leaned into the "cruiser" side of the racer-cruiser equation, incorporating more wood veneers and better stowage solutions. Headroom is respectable for a yacht of this vintage, typically hovering around 1.82 meters (6 feet) in the main cabin, which contributed to its enduring popularity as a weekend cruiser for families.

The Comet 910 is frequently cited in Italian nautical literature as the "Fiat 500 of the sea"—not because it was basic, but because it democratized performance sailing for an entire generation of Italian mariners. Its cultural footprint is most visible in European sailing journals, where it is often featured in "Classic Plastic" retrospectives. The yacht’s victory in the 1970s Middle Sea Race remains its most cited accolade, cementing its status as a high-performance icon of the Mediterranean.

Known Issues & Buyer’s Checklist

Prospective buyers of a Comet 910 should approach the vessel with the scrutiny required for a 40-to-50-year-old fiberglass yacht. While the hull is robustly built, specific areas require attention:

  1. Osmotic Blistering: Like many yachts of the 1970s, the Comet 910 is prone to osmosis. A thorough hull inspection is necessary to determine if the gelcoat has been breached or if a modern epoxy treatment has been applied.
  2. Chainplate Reinforcement: On early models, the chainplates and their attachment points to the bulkheads can show signs of stress or water ingress. Any "tea staining" or soft spots in the surrounding wood should be investigated.
  3. Original Engine Reliability: Many units were originally fitted with Farymann or Bukh diesel engines. While these were reliable in their time, parts are becoming scarce. A repowered unit (typically with a Volvo Penta or Yanmar) adds significant value and reliability.
  4. Rudder Play: The rudder bearings and the internal structure of the spade rudder can degrade over time. Excessive play in the tiller or signs of delamination on the rudder blade itself are common "gotchas" for this model.
  5. Deck Core Integrity: Check for delamination or "sponginess" around the mast step and the cockpit sole, which can occur if deck hardware has not been re-bedded periodically.

Community & Resources

Owners of the Comet 910 benefit from a dedicated community, particularly within Italy. The most prominent resource is the Comet Owners Association (Associazione Armatori Comet), which maintains technical archives and organizes rallies. While much of the technical documentation and forum discussion is in Italian, the sheer volume of boats produced means that technical advice and spare part dimensions are readily available through European maritime networks.

The Verdict

The Comet 910 remains a standout choice for the sailor who values pedigree and performance on a budget. It is a historical landmark that still sails circles around many modern cruisers of similar length.

Pros:

  • Exceptional sailing performance and historical racing pedigree.
  • Spacious interior for its era, suitable for coastal cruising.
  • Robust construction from a reputable Italian shipyard.
  • Timeless aesthetic that bridges the gap between classic and modern design.

Cons:

  • Age-related maintenance is inevitable (engines, osmosis, standing rigging).
  • Pinched stern and IOR hull shape can lead to some rolling in following seas.
  • Interior styling may feel dated compared to modern "condo-maran" style cruisers.
