Harpoon 62 Performance

How the Harpoon 62 performs on the water — racing handicap, sail-carrying power, stability and comfort.

+ Add to Compare

The Harpoon 62 is aggressively canvassed for its weight, 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.

5.3 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 15.8′, the Harpoon 62 tops out around 5.3 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √15.8′ LWL = 5.3 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
23.6
Performance-oriented — carries a lot of canvas for its weight.
Ballast / Displacement
32.4%
Typical cruising ballast — balanced stability and motion underway.
Displacement / Length
191
Moderate — a good balance of speed and load-carrying ability.
Comfort Ratio
9.6
Quick, snappy motion — better for day sails and racing than long passages.
Capsize Screening
2.68
Above the 2.0 offshore threshold — best suited for coastal and protected waters.

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
9.6
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
2.68
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 3.2 3.5 3.7
Close Reach60° 3.0 3.8 4.3 4.5
Beam Reach90° 3.7 4.7 5.3 5.7
Broad Reach120–135° 3.4 4.3 4.9 5.3
Run150–180° 2.8 3.5 3.9 4.1
These are simplified estimates based on hull speed (5.3 kts), SA/D (23.6), 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 Harpoon 62 — based on sail area, ballast, and displacement characteristics.

Heavy
0–5 kts 5–16 kts 16–24 kts 24+ kts
Ghosting
0–5 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
5–16 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
16–24 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
24+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
