The Contest 34 is modestly canvassed and unhurried, with a steady, comfortable ride offshore, designed for cruising comfort rather than racing.
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 27.6′, the Contest 34 tops out around 7.0 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √27.6′ LWL = 7.0 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
186s/nm
Typical cruiser — designed for comfort and ease, not podium finishes.
SA / Displacement
12.1
Modestly canvassed — a comfortable, unhurried cruiser.
Ballast / Displacement
43.2%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
347
Moderate-heavy — carries provisions well, deliberate in light air.
Comfort Ratio
34.4
Good offshore comfort — steady enough for multi-day passages.
Capsize Screening
1.76
Below the 2.0 offshore threshold — acceptable for ocean passages.
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
34.4
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
1.76
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 (7.0 kts),
SA/D (12.1), 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
0–8 kts
8–24 kts
24–34 kts
34+ kts
Ghosting
0–8 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
8–24 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
24–34 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
34+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
