Comar Comet 45 S Information, Review, Specs

The hull is constructed using advanced vacuum-infusion techniques, typically employing a GRP sandwich with an Airex or Termanto core to ensure a high strength-to-weight ratio. According to technical documentation from Comar Yachts, the 45 S features a low-profile deckhouse and the signature "loophole" windows that became a trademark of the Vallicelli-designed Comet series. The model shares its hull DNA and aesthetic philosophy with its larger sibling, the Comet 51 S, and its smaller counterpart, the Comet 41 S, effectively creating a unified range of performance cruisers that prioritize sleek Mediterranean styling.

Sailing Performance & Handling

The Comet 45 S is widely regarded for its agility and stiffness, traits derived from its generous 2.70m standard draft and a lead-bulb keel that provides a substantial righting moment. With a displacement of approximately 10,800 kg and a large fractional sloop rig, the boat exhibits a favorable sail area-to-displacement ratio (roughly 22 in racing trim), allowing it to excel in light-to-moderate Mediterranean breezes where heavier cruisers often struggle.

In sea trials reported by editorial sources such as itBoat, the 45 S is noted for its ability to track cleanly through waves, thanks to slender bow sections that minimize slamming. The high-aspect spade rudder provides precise feedback to the helm, and many units were delivered with twin carbon steering wheels to improve visibility and cockpit ergonomics. While the boat is stiff and stable, the large rig requires early reefing when the wind climbs above 18-20 knots to maintain an optimal heel angle and prevent excessive weather helm.

Interior Comfort & Variations

The interior of the Comet 45 S is characterized by high-quality Italian joinery, often finished in cherry or oak, which creates a warm and sophisticated atmosphere. One of the most distinctive features of the Vallicelli layout is the central positioning of the heads, a design choice that opens up the saloon and provides a more spacious, "loft-like" feel than traditional layouts. This configuration also improves the weight distribution by moving the plumbing and heavy fixtures closer to the boat's center of gravity.

Comar offered several variations of the 45 S to suit different owners. The most common layout features three cabins and two heads, with a large owner’s suite forward. However, a four-cabin variant was also produced to accommodate larger crews or charter requirements. The galley is typically arranged in a linear fashion along the port side or in a U-shape to starboard, depending on the specific year of production. The use of composite bulkheads, as detailed in reviews by Grabau International, allows for a light and airy interior without sacrificing structural integrity.

Known Issues & Buyer’s Checklist

Prospective buyers should approach the Comet 45 S with a focus on its performance-oriented engineering, which requires more rigorous maintenance than a standard coastal cruiser.

• Keel Attachment & Grid: Like many performance boats with high-aspect keels, the structural grid (the "matrix") should be inspected for any signs of stress cracking or delamination, particularly if the boat has a history of hard groundings. Some European owner circles have noted safety bulletins regarding keel bolt torque and plate inspections on certain Comet models.
• Engine Accessibility: The Lombardini engine (standard 40hp or 60hp) is located centrally under the companionway. While this is good for weight distribution, some owners find the access panels restrictive for major mechanical work.
• Rudder Bearings: Given the high loads placed on the high-aspect rudder, the bearings and steering cables should be checked for play or "notching," which can indicate wear or the need for lubrication.
• Teak Deck Wear: Many units were delivered with vacuum-bonded teak decks. Buyers should check for thinning of the wood or failing sealant, as replacement on a 45-foot deck is a significant capital expense.

Community & Resources

Owners of the Comet 45 S often coordinate through national associations, particularly in Italy and Croatia, where the model remains a staple of the offshore racing circuit. The most prominent resource for technical support and heritage data is the Comar Yachts shipyard directly, which maintains archives for the Vallicelli-designed "S" range.

The Verdict

The Comar Comet 45 S is an elegant, fast, and technically sophisticated performance cruiser that remains highly sought after on the brokerage market for its "crossover" capabilities.

Pros:

• Excellent light-air performance and high-speed potential.
• Stunning Mediterranean aesthetics with a modern, vertical-bow profile.
• Innovative interior layout that feels larger than 45 feet.
• High-end construction materials including vacuum-infused hulls and composite bulkheads.

Cons:

• Deep draft (2.70m) may limit access to some shallow-water cruising grounds.
• Standard Lombardini engines are less common in North America, complicating parts sourcing.
• Requires active sail management; the performance rig is not "set and forget."
