About the Biscayne 27 Sailboat

Designed by the legendary naval architecture firm Sparkman & Stephens and built by Spanish yard Astilleros Gallart beginning in 1962, this 27-footer represents classic yacht design from sailing's golden era. The wooden construction and traditional lines reflect the high standards expected from an S&S design, making it a sought-after vintage vessel among sailing enthusiasts who appreciate craftsmanship and heritage. With a displacement of 7,600 pounds and deep 6.5-foot draft, the Biscayne 27 offers substantial stability and seaworthiness that belies its modest size. The masthead sloop rig provides excellent sail handling characteristics, while the keel/centerboard configuration combines the tracking ability of a fixed keel with the shallow-water versatility of a lifting board. This hybrid design makes the boat particularly well-suited for coastal cruising and gunkholing in areas with varying depths. The comfort ratio of 29.19 indicates a relatively stiff, stable platform that handles choppy conditions well, while the capsize screening formula of 1.77 suggests reasonable offshore capability for experienced sailors. The SA/displacement ratio of 15.65 points to moderate performance that prioritizes comfort and control over pure speed, making this an ideal boat for relaxed coastal cruising and weekend adventures.
