S2 11.0A Performance

How the S2 11.0A performs on the water — racing handicap, speed, sail-carrying power, stability and comfort.

+ Add to Compare

The S2 11.0A 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.

7.1 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 28.2′, the S2 11.0A tops out around 7.1 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √28.2′ LWL = 7.1 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
299
Moderate-heavy — carries provisions well, deliberate in light air.
Comfort Ratio
28.2
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
1.91
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
7.1kts
Pounds/Inch Immersion
1,331lbs
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
28.2
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
1.91
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters
