Currawong 30 Performance

How the Currawong 30 performs on the water — racing handicap, sail-carrying power, stability and comfort.

+ Add to Compare

The Currawong 30 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.

6.8 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.

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
14.2
Moderate sail power — a capable coastal cruiser, not overpowered.
Ballast / Displacement
46.1%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
237
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
23.9
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
1.91
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
6.8kts
Pounds/Inch Immersion
5lbs
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
23.9
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
1.91
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° 2.5 3.1 3.5 3.7
Close Reach60° 3.0 3.8 4.2 4.4
Beam Reach90° 3.7 4.7 5.2 5.4
Broad Reach120–135° 3.4 4.3 4.8 5.0
Run150–180° 2.7 3.4 3.8 4.0
These are simplified estimates based on hull speed (6.8 kts), SA/D (14.2), 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.

Wind Range & Comfort Envelope

Estimated wind ranges for comfortable sailing on the Currawong 30 — based on sail area, ballast, and displacement characteristics.

Ghost
Sweet Spot
Reef
Heavy
0–7 kts 7–22 kts 22–32 kts 32+ kts
Ghosting
0–7 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
7–22 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
22–32 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
32+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
