About the Hurrican Island 30

Designed by Rodger Martin and built by Southport Marine Island LLC beginning in 2006, this distinctive 30-footer stands out with its unusual cat ketch rig featuring unstayed masts. The centerboard trunk configuration provides flexibility for shallow water exploration while maintaining respectable sailing performance, making it particularly well-suited for coastal cruising and gunkholing adventures. The Hurricane Island 30's fiberglass construction combines modern materials with a traditional sailing philosophy. Its relatively light displacement of 3,126 pounds and moderate ballast ratio create a boat that's responsive and easy to handle, while the unstayed rig simplifies maintenance and reduces the complexity typically associated with traditional rigging systems. The cat ketch configuration offers excellent balance and the ability to reduce sail incrementally by dropping either the main or mizzen. With a waterline length approaching 28 feet and moderate beam, this design strikes a practical balance between interior space and sailing efficiency. The low comfort ratio of 9.93 suggests a boat optimized more for performance and shallow water capability than heavy weather passage-making, while the capsize screening number indicates reasonable stability for coastal waters. This makes it an intriguing choice for sailors seeking a unique, easily-managed cruiser for exploring protected waters and shallow anchorages.

Performance Ratios
SA/Displacement Sail Area to Displacement ratio measures how much sail power a boat has relative to its weight. Higher values mean more performance and speed.
Under 14 — Heavy cruiser, slow14–18 — Cruising sailboat18–22 — Cruiser/racerOver 22 — Performance racer
25.51
Ballast/Displacement Ballast to Displacement ratio shows what percentage of the boat's total weight is ballast. Higher values generally mean better initial stability and stiffer sail carrying.
30–35% — Typical cruiser35–45% — Stiff performance boatOver 45% — Racing oriented
26.39
Displacement/Length Displacement to Length ratio measures how heavy a boat is relative to its waterline length. Lower values mean a lighter, faster boat.
Under 100 — Ultralight racer100–200 — Light cruiser/racer200–300 — Moderate cruiser300–400 — Heavy cruiserOver 400 — Very heavy
66.23
Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore
9.93
Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended
2.31
Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 7.04 kn
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 833.92 pounds/inch
