What is the Privilege 510's comfort ratio?

The Privilege 510 has a Ted Brewer Comfort Ratio of 14.23. A ratio over 30 indicates good offshore comfort; over 40 is very comfortable offshore.

Is the Privilege 510 safe for offshore sailing?

The Privilege 510 has a Capsize Screening Formula value of 3.15. Values under 2.0 are considered acceptable for offshore sailing; under 1.8 is ideal.

What is the hull speed of the Privilege 510?

The theoretical hull speed of the Privilege 510 is 9.44 kn knots, calculated from its waterline length.

How much does a Privilege 510 weigh?

The Privilege 510 has a displacement of 37,037.66 lb and a length overall (LOA) of 56.07 ft.

Who designed the Privilege 510?

The Privilege 510 was designed by Marc Lombard/Franck Darnet Design, first built in 2020.

Privilege 510 Performance — PHRF, SA/D, Hull Speed & Sailing Characteristics

The Privilege 510 is 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.

9.4 kts

A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 49.6′, the Privilege 510 tops out around 9.4 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.

1.34 × √49.6′ LWL = 9.4 kts

Performance Ratios

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

Comfort Ratio

14.2

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

Capsize Screening

3.15

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

Hull Speed

9.4kts

Pounds/Inch Immersion

28lbs

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

14.2

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

3.15

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
