The Rio 20 is a compact and spirited sailboat, emerging from the vibrant Brazilian marine industry in the mid-1970s. Designed by the esteemed naval architect Roberto Barros and built by MultiGlass, this 20-foot monohull was conceived to offer an accessible and engaging sailing experience. It quickly established itself as a notable vessel within the Brazilian sailing community, embodying a philosophy of functional and seaworthy design tailored for local conditions.

The genesis of the Rio 20 dates back to 1975, when MultiGlass began its production. This period marked a significant collaboration between the builder and Roberto Barros, whose yacht design business, Roberto Barros Yacht Design, was known for creating capable vessels. MultiGlass, itself a significant builder of fiberglass sailboats with roots tracing back to approximately 1980, played a crucial role in bringing Barros's visions to fruition, focusing on durable fiberglass construction that was becoming standard for recreational boats. The design philosophy behind Barros's creations, including the Rio 20, emphasized seaworthy and practical designs, appealing to both cruising and racing enthusiasts. While the Rio 20 saw continuous production for an unspecified period after its 1975 introduction, public records do not widely document significant variations or mark designations during its production run.
Sailing Performance and Handling
As a small sailboat, the Rio 20, with a length overall of just over 20 feet and a waterline length of 16.4 feet, is characterized by a design geared towards nimble handling and responsiveness. With a displacement of 1,764 pounds and a ballast of 661 pounds, it features a relatively light displacement, suggesting a lively performance, particularly in lighter air conditions. The fin keel design contributes to good directional stability and upwind performance, while the transom-hung rudder offers direct and responsive steering, making the boat agile and enjoyable to sail. These characteristics indicate a boat that is likely quick to accelerate and offers an engaging experience for day sailing or short excursions.
Accommodations and Layout
Due to its compact 20-foot length, the Rio 20's accommodations are designed for efficiency and practicality, typical of a boat in its class primarily intended for day sailing or very basic overnighting. While specific detailed layouts are not widely documented, a vessel of this size would typically feature a simple, open-plan cabin. This arrangement would likely include berths for a few crew members, possibly a V-berth forward, and minimal provisions for a small galley or head. The emphasis would be on maximizing usable space within the limited hull volume, providing shelter and essential amenities rather than extensive cruising comforts. Construction would primarily be fiberglass, consistent with MultiGlass's building practices, offering a robust and low-maintenance interior.
