Cape Cod 767 Performance & PHRF

The Cape Cod 767 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.

6.2 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

28.0

Performance-oriented — carries a lot of canvas for its weight.

Ballast / Displacement

28.8%

Light ballast — tends to be tender; reef earlier than the numbers suggest.

Displacement / Length

126

Ultralight — responsive and fast, but carries less stores.

Comfort Ratio

11.2

Quick, snappy motion — better for day sails and racing than long passages.

Capsize Screening

2.38

Above the 2.0 offshore threshold — best suited for coastal and protected waters.

Hull Speed

6.2kts

Pounds/Inch Immersion

4lbs

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

11.2

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

2.38

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°	2.9	3.7	4.1	4.3
Close Reach60°	3.5	4.5	5.0	5.2
Beam Reach90°	4.3	5.5	6.1	6.6
Broad Reach120–135°	4.0	5.1	5.7	6.1
Run150–180°	3.2	4.0	4.5	4.7

These are simplified estimates based on hull speed (6.2 kts), SA/D (28.0), 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 Cape Cod 767 — based on sail area, ballast, and displacement characteristics.

Ghost

Sweet Spot

Reef

Heavy

0–5 kts 5–14 kts 14–22 kts 22+ kts

Ghosting

0–5 kts

Light air, motor-sailing likely. Need patience and a light genoa.

Sweet Spot

5–14 kts

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

Time to Reef

14–22 kts

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

Heavy Weather

22+ kts

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