The Aloa Primvent 23, also widely known as the Aloa 23, is a compact French-built sailboat designed by the renowned naval architect J.M. L'Hermenier. Launched by Aloa Marine (originally SEB Marine), this monohull was conceived as an accessible and practical cruiser, embodying the builder's commitment to sturdy fiberglass construction and well-regarded hydrodynamic forms. With a length overall of just under 23 feet, the Primvent 23 offers a blend of performance and manageability, making it a suitable choice for coastal cruising and weekend adventures.

The Primvent 23 began its production run in 1967, with its official launch in 1968, and continued to be built until 1974, though some sources indicate production extending to 1979. Aloa Marine, based in Mandelieu, France, established a reputation for producing durable and seaworthy fiberglass yachts, a ethos that the Aloa 23 exemplified from its inception. Designer J.M. L'Hermenier's approach aligned with Aloa Marine's focus on creating practical and well-designed sailboats, setting a precedent for the shipyard's subsequent models. While the core design remained consistent, a notable variation, the Aloa 23R, emerged as a "racer" version, suggesting the model's adaptability for both cruising and more spirited regatta participation.

Sailing Performance and Handling

The Aloa Primvent 23's design specifications translate into a boat with good performance characteristics for its size. With a Sail Area to Displacement Ratio (SA/D) of approximately 17.95, it suggests a sailboat that is reasonably powered and capable of performing well in light to moderate air. Its Ballast to Displacement Ratio of around 0.389 indicates a decent level of stiffness, allowing it to stand up to a respectable amount of wind and providing a stable motion. The Displacement to Length (D/L) Ratio, calculated at roughly 172.33 (using long tons), places the Primvent 23 in the lighter, more performance-oriented category of cruisers for its length. Owners generally describe the Aloa 23 as a light and reasonably good performer, highlighting its stability and stiffness.

Accommodations and Layout

Despite its modest length, the Aloa Primvent 23 was designed to offer functional accommodations suitable for overnight stays and weekend trips. The interior typically features four berths, providing sleeping arrangements for a small crew or family. Essential amenities include a compact galley for food preparation and a dedicated toilet facility. While specific details on materials and finish quality are limited, the design prioritizes practicality, aligning with Aloa Marine's general approach to creating accessible and functional sailing yachts. The layout is characteristic of small cabin cruisers of its era, aiming to maximize usable space within its hull dimensions.
