Oceanis 321 Beneteau Performance

How the Oceanis 321 Beneteau performs on the water — racing handicap, speed, sail-carrying power, stability and comfort.

+ Add to Compare

The Oceanis 321 Beneteau is moderately powered for comfortable coastal cruising.

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 27.9′, the Oceanis 321 Beneteau tops out around 7.1 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √27.9′ 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.

SA / Displacement
16.1
Moderate sail power — a capable coastal cruiser, not overpowered.
Ballast / Displacement
34.8%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
209
Moderate — a good balance of speed and load-carrying ability.
Hull Speed
7.1kts
Pounds/Inch Immersion
7lbs
Weight needed to sink the hull one inch — loading sensitivity.

Estimated Speed by Wind

Rough boat speed estimates at different true wind speeds and points of sail — derived from hull speed, SA/D, and displacement, not measured polars.

Point of Sail 6 kts TWS 10 kts TWS 15 kts TWS 20 kts TWS
Close-hauled40–50° 2.8 3.5 3.9 4.1

Broad Reach120–135° 3.8 4.8 5.3 5.6

These are simplified estimates based on hull speed (7.1 kts), SA/D (16.1), 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

Estimated wind ranges for comfortable sailing on the Oceanis 321 Beneteau — based on sail area, ballast, and displacement characteristics.

Ghost

Heavy
0–7 kts 7–20 kts 20–28 kts 28+ kts
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.
