Costantini 30 Information, Review, Specs

The creation of the Costantini 30 falls within a significant period for Chantier Naval Costantini, a shipyard founded by Louis Costantini and later led by his sons, Gilles and Marc Costantini. The shipyard, operating until 1979, was at the forefront of embracing innovative construction methods, particularly with materials like plywood and "plastic composite materials" (likely referring to fiberglass) for lighter and more efficient designs. The Costantini 30 itself was constructed in plywood, showcasing the builder's pragmatic adoption of new materials. Designed by Gilles Costantini, who also designed the iconic Pen Duick II, the Costantini 30 emerged during an era when the shipyard was known for its willingness to experiment and collaborate with leading naval architects. There is no information available to suggest significant variations in the Costantini 30 during its limited production run of five units.

Sailing Performance and Handling

The Costantini 30, with a length overall of 30.35 feet and a waterline length of 22.64 feet, is designed for a balance of performance and stability. Its calculated Sail Area to Displacement (SA/D) ratio of approximately 17.30 suggests a vessel capable of performing adequately in light to moderate winds, indicating it is neither a sluggish cruiser nor a high-performance racer. The Ballast to Displacement (B/D) ratio of 0.50 is notably high, indicating excellent stiffness and stability, allowing the boat to stand up well to a breeze and providing a comfortable motion in a seaway. With a Displacement to Length (D/L) ratio of around 229.05, the Costantini 30 is classified as a moderately heavy cruiser, offering a solid feel without being overly ponderous. The boat's fin keel and spade rudder contribute to good maneuverability, while its maximum draft of 5.64 feet allows it to access most marinas.

Accommodations and Layout

Detailed information regarding the interior accommodations and layout of the Costantini 30 is scarce in available public records. While the vessel's length overall of just over 30 feet suggests typical amenities for a cruiser of its size from the early 1970s, specific details on the cabin arrangement, such as the number of berths, galley configuration, or head placement, are not readily available. The maximum headroom within the cabin is also not recorded in the provided specifications. Owners seeking to understand the interior would likely need to consult historical reviews or blueprints if they can be located.
