The Comet 333, produced by Italy’s Comar Yachts during the late 1990s and early 2000s, represents a pivotal moment in the shipyard's transition from traditional IORinfluenced designs to modern, highperformance cruisers. Designed by naval architect Sergio Lupoli, the 333 was conceived as a "fast cruiser" that could comfortably accommodate a family while remaining competitive in club racing circuits. It evolved from the design philosophy of the earlier Comet 303 but introduced a more aggressive hull form, a refined fractional rig, and the signature Italian "sportchic" interior that defined Comar Yachts during the Massimo Guardigli era. By blending a light displacement with a generous sail plan, the 333 successfully targeted the Mediterranean market, where lighttomoderate air performance is a primary requirement for any serious coastal cruiser.

Sailing Performance & Handling

Under sail, the Comet 333 is characterized by its responsiveness and "lightness" at the helm. The boat features a high-aspect-ratio fractional rig that allows for fine-tuned sail control, a trait often cited in Italian nautical reviews as a key differentiator from its more utilitarian French counterparts. With a displacement-to-length ratio that leans toward the performance end of the spectrum, the 333 accelerates quickly in puffs and maintains impressive momentum through tacks.

The hull design utilizes a relatively narrow waterline beam that flares toward the deck, providing a good balance between low wetted surface area in light winds and increased form stability as the boat heels. Owners typically report that the 333 feels most balanced at a heel angle of 15 to 20 degrees; beyond this point, the deep-fin keel (drawing approximately 1.90 meters) provides the necessary leverage to prevent excessive leeway. The rudder is deep and balanced, providing enough grip to prevent rounding up in heavy gusts, though the boat requires active mainsheet trimming to maintain optimal speed in "white-knuckle" conditions.

Interior Comfort & Variations

Despite its performance-oriented hull, the interior of the Comet 333 reflects Comar’s commitment to "Made in Italy" craftsmanship. The layout is a classic Mediterranean arrangement: a V-berth forward, a central salon with twin longitudinal settees, and a large double cabin tucked under the cockpit on the port side. The use of light-colored woods, often cherry or light oak, combined with numerous deck hatches, creates an airy feel that belies the boat's 10-meter length.

The galley is typically L-shaped and situated to starboard, featuring a gimbaled stove and a top-loading refrigerator. A notable variation in the 333’s production run was the choice of keel depths and mast heights; "Sport" versions often featured a taller rig and lead-bulbed keels, while "Cruising" versions prioritized a more manageable sail area and a slightly shallower draft. The sibling model, the Comet 33, serves as the direct successor, sharing much of the 333’s DNA but featuring modernized deck hardware and a revised stern profile to accommodate a more integrated swim platform.

Known Issues & Buyer’s Checklist

Purchasing a Comet 333 requires a specific focus on the structural and mechanical elements inherent to performance-cruisers of this vintage.

  1. Grid and Liner Bonding: Like many production boats built with an internal structural grid, the 333 can occasionally show signs of "crazing" or detachment in the fiberglass liner near the mast step or keel bolts if the boat has been raced hard or grounded. A surveyor should check for any "pumping" in the hull-to-grid bond.
  2. Saildrive Diaphragm: Most 333s were equipped with Yanmar or Volvo Penta engines utilizing saildrives. It is critical to verify the age of the rubber saildrive seal; manufacturers recommend replacement every 7 to 10 years, and a failure here can be catastrophic.
  3. Deck Hardware Sealing: The 333 uses high-quality deck gear (often Harken or Lewmar), but the through-bolts for the jib tracks and organic blocks can develop leaks over time. Buyers should inspect the interior headliner for water stains, which may indicate the need for re-bedding hardware.
  4. Rudder Bearing Wear: Due to its deep, high-aspect rudder, the bearings can experience significant side-loading. Check for "play" or vibration in the steering system when the boat is out of the water.

Community & Resources

The primary hub for technical data and owner support is the Associazione Comet, an Italian-based owner's group that maintains archives for various Comet models. While most official documentation is in Italian, the community is highly active in the Mediterranean and provides a wealth of knowledge regarding specific Lupoli design quirks. Technical drawings and historical brochures are occasionally maintained by the original builder at Comar Yachts.

The Verdict

The Comet 333 is a sophisticated choice for the sailor who refuses to accept the sluggish performance of traditional entry-level cruisers. It offers a level of aesthetic and sailing "finesse" rarely found in the 33-foot category.

Pros:

  • Exceptional Agility: Outperforms most cruisers of its size in light-to-moderate winds.
  • Elegant Interior: High-quality joinery and a layout that maximizes the perception of space.
  • Strong Pedigree: A Sergio Lupoli design backed by Comar’s long history of performance yachting.

Cons:

  • Limited Headroom: Taller sailors may find the forward cabin and head area somewhat cramped.
  • Active Sailing Required: Not a "set it and forget it" cruiser; requires frequent sail adjustment to stay in the groove.
  • Availability: Harder to find in North American markets, as production was heavily concentrated in Europe.
