Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
5.7 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 18.2′, the Arrow Ss tops out around 5.7 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √18.2′ LWL = 5.7 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Ballast / Displacement
50.0%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
89
Ultralight — responsive and fast, but carries less stores.
Hull Speed
5.7kts
Pounds/Inch Immersion
2lbs
Weight needed to sink the hull one inch — loading sensitivity.
