The Pyramid 660 stands as a distinctive, albeit rare, example of a compact performance sailboat, a testament to the design prowess of the acclaimed American naval architect Carl Schumacher. Built by Pyramid Boat Works of San Leandro, California, this 21-foot 8-inch monohull was conceived as a nimble and speedy vessel, embodying Schumacher's philosophy of innovative and efficient hull forms. With only approximately five units ever produced, the Pyramid 660 represents a unique chapter in the history of smaller, specialized boat builders.

History and Design
Production of the Pyramid 660 commenced in 1982. The vessel was the product of a collaboration between Pyramid Boat Works, founded by Jack Sheldon in San Leandro, California, and the celebrated designer Carl Schumacher, 8]. Pyramid Boat Works, which operated primarily in the early 1980s before ceasing operations, was known for its focus on specific design partnerships and a dedication to craft, utilizing fiberglass as its primary construction material.
Carl Schumacher, who established his own design firm in 1977, was a highly influential figure in sailboat design, leaving a significant mark on both custom and production boats, including the popular Express and Alerion-Express lines. His design philosophy emphasized performance, innovation, and efficient sailing characteristics, 4, 7]. For the Pyramid 660, Schumacher opted for a significantly more speedy hull design, which is notably slimmer than 98% of other similar sailboat designs. This design choice reflects a clear intent to create a boat that excelled in performance.
Sailing Performance and Handling
The Pyramid 660, with its length overall of 21.8 feet and a waterline length of 18.08 feet, features a fin keel and a spade rudder, a combination characteristic of performance-oriented designs. Its fractional sloop rig, with a reported sail area of 200 square feet, further contributes to its agility and responsiveness. The design prioritizes speed, evidenced by its exceptionally slender hull.
This design suggests the Pyramid 660 is a lively performer, capable of exciting sailing. The combination of a fin keel and spade rudder typically provides excellent maneuverability and a balanced helm, making it responsive to input. Anecdotal evidence from owners reflects a strong positive sentiment, with at least one past owner expressing regret at parting with the boat, indicating an enjoyable sailing experience.
Accommodations and Layout
Given its compact length of just under 22 feet and its design emphasis on performance through a slender hull, the accommodations on the Pyramid 660 would be considered spartan, typical of small racing-oriented sailboats of its era. While specific interior layouts are not readily available in detailed reviews or diagrams, it is reasonable to infer a basic arrangement. Such a layout would likely include a V-berth forward, possibly convertible into a small seating area, and minimal space for a marine head. Headroom would be limited, and storage would be modest, suitable for weekend excursions or day sailing rather than extended cruising. The finish quality would likely reflect the builder's focus on structural integrity and sailing efficiency, with functional rather than luxurious materials. Detailed information on the interior layout is scarce due to the boat's limited production run.
