The Contessa 43 is well-powered with enough sail area to move in light air, with a steady, comfortable ride offshore, and competitive on the racecourse.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 34.3′, the Contessa 43 tops out around 7.9 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √34.3′ LWL = 7.9 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
69s/nm
Performance racer — quick around the cans and offshore.
SA / Displacement
18.5
Powerful cruiser/racer — quick in light air, reef early when it pipes up.
Ballast / Displacement
51.4%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
232
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
30.5
Good offshore comfort — steady enough for multi-day passages.
Capsize Screening
1.82
Below the 2.0 offshore threshold — acceptable for ocean passages.
Pounds/Inch Immersion
9lbs
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
30.5
Good offshore comfort — steady enough for multi-day passages.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
1.82
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters

These are simplified estimates based on hull speed (7.9 kts),
SA/D (18.5), and empirical efficiency curves — not instrument-measured
polars. Real-world speed varies with sea state, bottom condition, sail trim, and current.
Speeds in gold approach hull speed;
bold gold means near or at hull speed.
Wind Range & Comfort Envelope

Heavy
0–6 kts
6–20 kts
20–30 kts
30+ kts
Ghosting
0–6 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
6–20 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
20–30 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
30+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
