Tarann Information, Review, Specs

History and Design

The creation of the Tarann falls within a significant period for Chantier Naval Costantini, specifically under the leadership of Gilles and Marc Costantini, who took the helm in 1957. During this time, the shipyard pioneered the use of materials like plywood, aluminum, and "plastic composite materials," which refers to fiberglass, to construct lighter, more efficient, and cost-effective boats. This forward-thinking approach, described as a pragmatic adoption of new materials, shaped their design philosophy. The Tarann, built with a solid fiberglass hull and deck, exemplifies Costantini's commitment to these cutting-edge construction methods of the early 1960s. The design goals for the Tarann, penned by Gilles Costantini, likely emphasized robust stability, as its high ballast-to-displacement ratio suggests a design focused on a superior righting moment compared to many similar sailboats of its time.

Sailing Performance and Handling

The Tarann's design specifications translate into a sailboat with notable performance characteristics for its era. With a sail area to displacement ratio (SA/D) of approximately 22.19, she is expected to perform commendably in lighter air conditions, making efficient use of her sail plan. Her ballast to displacement ratio (B/D) of around 0.478 is remarkably high, indicating exceptional stiffness and stability. This suggests the Tarann is capable of standing up to a considerable amount of wind, offering a secure and controlled sailing experience even when conditions become more demanding. The displacement to length ratio (D/L) of approximately 270.2 positions the Tarann as a moderate to heavy displacement vessel, leaning towards a traditional cruiser-racer profile. While potentially not the fastest in light conditions, this displacement, combined with her high stability, would contribute to a comfortable motion in a seaway.

Accommodations and Layout

Information regarding the specific interior accommodations and layout of the Tarann is not extensively documented in available public records. While the vessel measures just over 31 feet in length overall, detailed descriptions, diagrams, or typical arrangements of its V-berth, head, salon, or galley are not readily available through grounded search. The maximum headroom of the Tarann is also not specified in the provided data. Therefore, a comprehensive overview of its interior design, finish quality, materials used, storage solutions, or ventilation cannot be provided.
