About the Trimax 1080

Produced by the Australian builder Trimax, the 1080 is a trailerable sailing dinghy or small keelboat designed with accessibility and versatility in mind. With a focus on straightforward handling, this boat appeals to sailors looking for an entry point into recreational sailing or a reliable platform for casual coastal and bay sailing rather than demanding offshore passages. The Trimax range has generally been associated with practical, no-fuss designs built for the Australian market, where trailerable boats that can be launched from local ramps and sailed on sheltered waterways enjoy strong popularity. The 1080 fits neatly into this tradition, offering a manageable size that suits beginners and intermediate sailors while remaining approachable enough for family use. Detailed specification data for the 1080 is limited, which can make direct comparisons with similar boats somewhat challenging. Prospective buyers would be well advised to seek out existing owners through Australian sailing forums or clubs to gather firsthand accounts of performance and build quality. Inspecting a used example in person remains the most reliable way to assess whether this boat suits your sailing ambitions.

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
27.08
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
67.4
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
3.24
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
6.09
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. 7.87 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. 20.59 pounds/inch
