The Oceanis 50 Beneteau is moderately powered for comfortable coastal cruising, with acceptable motion comfort for coastal passages.
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 43.3′, the Oceanis 50 Beneteau tops out around 8.8 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √43.3′ LWL = 8.8 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
SA / Displacement
17.2
Moderate sail power — a capable coastal cruiser, not overpowered.
Ballast / Displacement
33.3%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
182
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
29.2
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
1.93
Below the 2.0 offshore threshold — acceptable for ocean passages.
Pounds/Inch Immersion
14lbs
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
29.2
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
1.93
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters
Estimated Speed by Wind

These are simplified estimates based on hull speed (8.8 kts),
SA/D (17.2), 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.

Ghosting
0–7 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
7–20 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
20–28 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
28+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
