Red Witch 19 Performance

Hull Speed

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

5.4 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.

Ballast / Displacement

45.4%

Race-oriented ballast ratio — very stiff and powerful.

Displacement / Length

143

Ultralight — responsive and fast, but carries less stores.

Comfort Ratio

8.9

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

Hull Speed

5.4kts

Pounds/Inch Immersion

3lbs

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

8.9

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
