Sintesi 45 Information, Review, Specs

The Sintesi 45 emerged from Cantiere Rinaldi, a shipyard nestled in Monticelli Brusati, Italy, closely associated with Ettore Rinaldi. The yard began its journey around the early 1990s, with the Sintesi 45 being one of its earliest and most prominent models, first built in 1993. Cantiere Rinaldi established itself by producing sailboats recognized for their practical design and performance, utilizing fiberglass (vetroresina) as a primary construction material. The Sintesi 45, specifically, was a joint design effort between Ettore Santarelli and the yard's owner. Notably, the Sintesi 45 was considered an "ULDB" (ultra-light displacement boat) for its era, weighing approximately 6,500 kg (14,330 lbs) and featuring a sandwich hull construction, a testament to its forward-thinking design philosophy aimed at performance.

Sailing Performance and Handling

The design of the Sintesi 45 by Ettore Santarelli prioritizes spirited performance, evident in its calculated ratios. With a Sail Area to Displacement Ratio (SA/Disp) of approximately 22.58, the Sintesi 45 possesses a generous sail plan relative to its weight, indicating strong potential for performance, particularly in lighter wind conditions. Its Ballast to Displacement Ratio (Bal/Disp) stands at about 0.281. While this figure is on the lower side for a cruising vessel, it aligns with a performance-oriented design where stiffness might be achieved through hull form rather than solely heavy ballast, prioritizing speed. The Displacement to Length Ratio (Disp/LWL) of approximately 274.0 further contextualizes its design. Although this number might suggest a moderately heavy boat by modern ultra-light standards, it was considered "ultra-light" for its time, reflecting a design ethos that aimed for a more agile and faster vessel compared to the heavier cruisers prevalent in its production era.

Equipped with a fin keel and a spade rudder, the Sintesi 45 is designed to offer splendid maneuverability. It features a masthead sloop rig, providing a robust sail plan for various conditions. Anecdotal reports from owners suggest that the boat is capable of achieving impressive speeds, with one forum discussion indicating speeds of around 8 knots, reinforcing its character as a fast passage maker.

Accommodations and Layout

The interior of the Sintesi 45 is designed for comfortable cruising, offering a practical layout beneath its performance-oriented exterior. Typical configurations include three double cabins, providing ample sleeping accommodations for up to six to eight individuals, alongside a single head. The forward section often features a main double berth cabin, complete with an opening roof hatch and a comfortable 4-inch foam mattress. Additional double cabins are typically located aft, with hanging storage available. The interior finish often incorporates carpeted walls in the cabins and foam-backed vinyl ceilings, contributing to a cozy and insulated environment. The vessel is also well-equipped for extended voyages, boasting a fresh water capacity of 111 US gallons (420 liters). Constructed with a fiberglass hull, the Sintesi 45 also benefits from relatively low maintenance requirements during the sailing season.
