Cutlass 27 Performance

How the Cutlass 27 performs on the water — racing handicap, sail-carrying power, stability and comfort.

+ Add to Compare

The Cutlass 27 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.

6.0 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 20.0′, the Cutlass 27 tops out around 6.0 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √20.0′ LWL = 6.0 kts

Performance Ratios

Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.

SA / Displacement
13.4
Modestly canvassed — a comfortable, unhurried cruiser.
Ballast / Displacement
50.0%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
363
Heavy displacement — a slow, steady, seakindly hull.
Comfort Ratio
30.1
Good offshore comfort — steady enough for multi-day passages.
Capsize Screening
1.65
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
6.0kts
Pounds/Inch Immersion
3lbs
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
30.1
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
1.65
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° 2.1 2.7 3.0 3.1
Close Reach60° 2.6 3.3 3.7 3.8
Beam Reach90° 3.2 4.0 4.5 4.7
Broad Reach120–135° 2.9 3.7 4.1 4.3
Run150–180° 2.3 3.0 3.3 3.5
These are simplified estimates based on hull speed (6.0 kts), SA/D (13.4), 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 Cutlass 27 — based on sail area, ballast, and displacement characteristics.

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.
