The Us 30 is designed for cruising comfort rather than racing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
6.7 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 25.0′, the Us 30 tops out around 6.7 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √25.0′ LWL = 6.7 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
168s/nm
Typical cruiser — designed for comfort and ease, not podium finishes.
Ballast / Displacement
40.7%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
200
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
6.7kts
Pounds/Inch Immersion
5lbs
Weight needed to sink the hull one inch — loading sensitivity.
