The Asso 99 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.
7.1 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Displacement / Length
51
Ultralight — responsive and fast, but carries less stores.
Comfort Ratio
6.2
Quick, snappy motion — better for day sails and racing than long passages.
Hull Speed
7.1kts
Pounds/Inch Immersion
6lbs
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
6.2
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
