The genesis of the Atoll 23 is closely intertwined with the establishment of its builder, MultiGlass, around 1980 in Brazil. The company's early history is deeply rooted in the vision of Roberto Barros, who began his yacht design business by creating boats for "his own boatyard," suggesting a foundational partnership with MultiGlass as the primary manufacturer of his initial designs. 5, 7, Builder Article

While largely known as the Atoll 23, the model's lineage can be traced back to an earlier iteration, the Atoll 22, launched in the 1970s. Shortly after its introduction, the design evolved into the Atoll 23, marking its official production start around 1980. Crafted from solid fiberglass for both hull and deck, the Atoll 23 features a fin keel and a skeg-hung rudder, choices that reflect Roberto Barros's emphasis on functional and seaworthy designs. This construction method was becoming standard for recreational boats during that era, offering durability and ease of maintenance.

Sailing Performance and Handling

The Atoll 23, with a length overall of 23.13 feet and a waterline length of 18.54 feet, is characterized by its light displacement of 2491 pounds and a reported sail area of 316 square feet. These dimensions, combined with its fractional sloop rig, contribute to its reputation as a nimble and responsive vessel. While often described as a popular cruiser, its characteristics also suggest a boat capable of lively performance., 1]

Equipped with a fin keel and a skeg-hung rudder, the Atoll 23 offers splendid maneuverability, making it responsive to helm input. The fin keel design, while excellent for turning, tends to provide less directional stability compared to longer keel configurations. Its hull speed is calculated at 5.77 knots, indicating efficient performance for its size. This combination of design elements allows the Atoll 23 to be both an enjoyable boat for leisurely cruises and a capable performer when the sails are trimmed for speed.

Accommodations and Layout

The interior layout of the Atoll 23, while generally modest given its compact size, is designed to provide essential comforts for coastal cruising. Specific detailed descriptions of the interior accommodations are not widely publicized, but owners undertaking renovations have noted the presence of electrical, hydraulic, and interior systems, indicating a functional, if compact, living space. Typical arrangements for boats of this size would include basic sleeping berths, a small galley area, and potentially a compact head, optimized for efficient use of the available volume. The solid fiberglass construction extends to the interior, providing a robust and easy-to-maintain finish.
