The Nonsuch 40 is with acceptable motion comfort for coastal passages.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
8.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 40.0′, the Nonsuch 40 tops out around 8.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √40.0′ LWL = 8.5 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
Displacement / Length
187
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
29.5
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
1.89
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
8.5kts
Pounds/Inch Immersion
2lbs
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
29.5
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
1.89
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters
