About the A Lion Sailboat

Designed by the Hubbard brothers Jerry and David in 1967, this compact catamaran represents an early entry into the American small multihull market. American Fiberglass Corporation brought this twin-centerboard design to production during the late 1960s, capitalizing on growing interest in catamaran sailing among recreational sailors. At 18 feet overall with a 7.5-foot beam, the A Lion offers the characteristic stability and speed potential that draws sailors to multihull designs. The twin centerboard configuration provides versatility for both shallow water exploration and deeper water sailing, while the relatively light 300-pound displacement contributes to spirited performance in moderate conditions. Her Marconi cat rig keeps sail handling straightforward, making this an approachable choice for sailors transitioning from monohulls or those seeking uncomplicated catamaran sailing. With 150 square feet of sail area driving the lightweight fiberglass hulls, the A Lion delivers the quick acceleration and reduced heeling that catamaran enthusiasts appreciate. This design suits coastal cruising, day sailing, and casual racing where her SA/Displacement ratio of 53.61 suggests lively performance in light to moderate winds. The shallow 2.5-foot draft opens up skinny water venues often inaccessible to deeper-draft vessels.
