Morgan Out Island 41 Performance

How the Morgan Out Island 41 performs on the water — racing handicap, sail-carrying power, stability and comfort.

+ Add to Compare

The Morgan Out Island 41 is modestly canvassed and unhurried, with a steady, comfortable ride offshore.

Hull Speed

The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.

7.8 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 34.0′, the Morgan Out Island 41 tops out around 7.8 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √34.0′ LWL = 7.8 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
12.0
Modestly canvassed — a comfortable, unhurried cruiser.
Comfort Ratio
34.9
Good offshore comfort — steady enough for multi-day passages.
Capsize Screening
1.85
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed

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
34.9
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
1.85
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

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° 2.7 3.4 3.8 3.9
Close Reach60° 3.2 4.1 4.5 4.7

Broad Reach120–135° 3.6 4.6 5.2 5.4
Run150–180° 2.9 3.7 4.1 4.3
These are simplified estimates based on hull speed (7.8 kts), SA/D (12.0), 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 Morgan Out Island 41 — based on sail area, ballast, and displacement characteristics.

0–8 kts 8–22 kts 22–30 kts 30+ kts
Ghosting
0–8 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
8–22 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
22–30 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.
