Ganbare 35 Performance

How the Ganbare 35 performs on the water — racing handicap, speed, sail-carrying power, stability and comfort.

+ Add to Compare

The Ganbare 35 is moderately powered for comfortable coastal cruising, with acceptable motion comfort for coastal passages, and respectable in club racing.

Hull Speed

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

7.2 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 28.5′, the Ganbare 35 tops out around 7.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √28.5′ LWL = 7.2 kts

Performance Ratios

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

PHRF Rating
111s/nm
Cruiser/racer — competitive in club racing, comfortable cruising.

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
26.6
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

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° 2.9 3.6 4.0 4.2
Close Reach60° 3.5 4.4 4.9 5.1

Broad Reach120–135° 3.9 5.0 5.5 5.8
Run150–180° 3.1 4.0 4.4 4.6
These are simplified estimates based on hull speed (7.2 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.

Wind Range & Comfort Envelope

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
