Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.6 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 32.0′, the Young Sun 35 tops out around 7.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √32.0′ LWL = 7.6 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
34.9%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
262
Moderate-heavy — carries provisions well, deliberate in light air.

Pounds/Inch Immersion
8lbs
Weight needed to sink the hull one inch — loading sensitivity.
