Indian Performance

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

+ Add to Compare

The Indian is well-powered with enough sail area to move in light air, with a quick, snappy motion best suited to day sailing.

Hull Speed

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

5.5 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 16.8′, the Indian tops out around 5.5 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √16.8′ LWL = 5.5 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
303s/nm
Heavy or slow cruiser — all about the journey, not the elapsed time.
SA / Displacement
21.8
Powerful cruiser/racer — quick in light air, reef early when it pipes up.
Ballast / Displacement
25.7%
Light ballast — tends to be tender; reef earlier than the numbers suggest.
Displacement / Length
166
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
13.0
Quick, snappy motion — better for day sails and racing than long passages.
Capsize Screening
2.08
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Hull Speed
5.5kts
Pounds/Inch Immersion
374lbs
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
13.0
Quick, snappy motion — better for day sails and racing than long passages.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
2.08
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
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 3.6
Close Reach60° 3.0 3.8 4.2 4.4

Broad Reach120–135° 3.4 4.3 4.8 5.2
Run150–180° 2.7 3.4 3.8 4.0
These are simplified estimates based on hull speed (5.5 kts), SA/D (21.8), 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 Indian — based on sail area, ballast, and displacement characteristics.

Heavy
0–6 kts 6–16 kts 16–24 kts 24+ kts
Ghosting
0–6 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot

Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef

Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather

Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
