About the Ss 24 Sailboat

Designed by the legendary naval architecture firm Sparkman & Stephens, this compact 24-footer represents classic yacht design principles scaled down to a trailerable package. Built by Sea Nymph in New Zealand between 1968 and 1973, only twenty of these fiberglass sloops were produced, making them a rare find in today's market. The Ss 24's proportions reflect S&S's commitment to seaworthiness over pure speed. With a displacement of 4,640 pounds and substantial ballast-to-displacement ratio, she carries herself with the stability of a much larger yacht. The fin keel configuration and masthead sloop rig deliver respectable sailing performance while maintaining excellent directional stability. Her comfort ratio of 23.12 and capsize screening value of 1.84 indicate a boat well-suited for coastal cruising and weekend adventures, though her solid construction and conservative design would handle moderate offshore conditions confidently. The cockpit and interior layout prioritize functionality over luxury, typical of the era's approach to small yacht design. While not a speed demon, the Ss 24 rewards sailors who appreciate traditional sailing characteristics and build quality. Her Sparkman & Stephens pedigree ensures sound sailing manners and lasting value for those fortunate enough to find one of these uncommon gems.
