The Trailertri 720 is with a quick, snappy motion best suited to day sailing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
6.2 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 21.7′, the Trailertri 720 tops out around 6.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √21.7′ LWL = 6.2 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Comfort Ratio
4.5
Quick, snappy motion — better for day sails and racing than long passages.
Capsize Screening
4.69
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Hull Speed
6.2kts
Pounds/Inch Immersion
8lbs
Weight needed to sink the hull one inch — loading sensitivity.
Motion & Offshore Suitability
Two ratios that matter most when you're planning passages — how the boat feels in a seaway, and whether the hull geometry is suitable for open ocean.
Comfort Ratio
4.5
Quick, snappy motion — better for day sails and racing than long passages.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
4.69
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters
