Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 31.5′, the Scanner 392 tops out around 7.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √31.5′ LWL = 7.5 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
40.2%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
192
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
7.5kts
Pounds/Inch Immersion
8lbs
Weight needed to sink the hull one inch — loading sensitivity.
