The Hudson Force 50 is with a gentle bluewater motion, and respectable in club racing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.4 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 39.0′, the Hudson Force 50 tops out around 8.4 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √39.0′ LWL = 8.4 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
138s/nm
Cruiser/racer — competitive in club racing, comfortable cruising.
Ballast / Displacement
21.2%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
391
Heavy displacement — a slow, steady, seakindly hull.
Comfort Ratio
55.3
Very comfortable in a seaway — a genuine bluewater motion.
Capsize Screening
1.52
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
8.4kts
Pounds/Inch Immersion
1lbs
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
55.3
Very comfortable in a seaway — a genuine bluewater motion.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
1.52
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters
