The Alpa A11 is a distinguished monohull sailboat, measuring just over 37 feet in length overall, conceived by the celebrated British naval architect John Illingworth. Launched into production in 1968 by the Italian shipyard Alpa Yachts, the A11 quickly earned a reputation as a robust and capable cabin cruiser, ideal for offshore voyaging and comfortable coastal exploration. Often lauded as a "masterpiece" and a "cult favorite" among enthusiasts, the Alpa A11 represents a significant fiberglass iteration of Illingworth's renowned MAICA design, a vessel frequently referenced in his seminal work, "Heavy Weather Sailing".

History and Design
The Alpa A11 began its production run in 1968, emerging from the pioneering Alpa Yachts shipyard in Italy. Alpa, founded by Danilo Cattadori in 1956, was at the forefront of the "true revolution" in nautical engineering by embracing fiberglass as a primary construction material for boats in Europe. This commitment to robust fiberglass construction and collaboration with esteemed naval architects like John Illingworth defined Alpa's manufacturing ethos during this era.
John Illingworth, assisted by Angus Primrose for the later "Super Maica" version, was a highly regarded and successful yacht designer. His design philosophy for the Alpa A11, drawing directly from the MAICA, centered on creating a seaworthy and reliable vessel, a theme consistent with the principles discussed in his influential book, "Heavy Weather Sailing". The Alpa A11 was notably produced in two distinct versions: the original "Maica" and the subsequent "Super Maica".
Sailing Performance and Handling
With a reported sail area to displacement ratio (SA/Disp) of approximately 14.72, the Alpa A11 is characterized as a moderate performer, indicative of a cruising yacht rather than a light-air racer. Her displacement to length ratio (Disp/LWL) of 363.16 further classifies her as a heavy, traditional cruiser. This higher displacement suggests a design focused on comfort and stability in a seaway, rather than outright speed, aligning with the "marine and safe" attributes often ascribed to the model.
While specific anecdotal descriptions of the Alpa A11's handling in various sea states are not extensively documented, its design lineage and heavy displacement imply a boat with a comfortable motion offshore and good stability. The exact ballast-to-displacement ratio for the Alpa A11 is not readily available from general specifications, making a direct qualitative assessment of its stiffness challenging. However, the overall design points to a capable and predictable vessel for its intended cruising purpose.
Accommodations and Layout
Despite the limited detailed information in standard specifications, the interior of the Alpa A11 was designed to provide essential comforts for cruising. Below deck, the layout typically features four berths, a functional galley area, and a toilet, offering the basic necessities for extended stays aboard. While specific details regarding headroom, finish quality, materials, or ventilation are not widely published, a boat of this era and designer often emphasized practical, durable interiors, likely featuring traditional wood trim alongside fiberglass elements.
Owner's Perspectives
Owners and enthusiasts generally hold the Alpa A11 in high regard, often referring to it as a "great boat" and a "cult favorite". Its association with John Illingworth and the reputation of Alpa Yachts for solid fiberglass construction contribute to its standing as a respected classic. While specific common maintenance issues or recurring problems are not frequently cited in public reviews, the enduring presence and appreciation for these vessels suggest that owners value their robust build and seaworthy characteristics.
