Rivage 39 Performance

Hull Speed

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

7.8 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.

Displacement / Length

179

Moderate — a good balance of speed and load-carrying ability.

Comfort Ratio

21.6

Acceptable coastal comfort — fine for weekends, notice the chop offshore.

Hull Speed

7.8kts

Pounds/Inch Immersion

9lbs

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

21.6

Acceptable coastal comfort — fine for weekends, notice the chop offshore.

Under 20 — Snappy, racing motion

20–30 — Acceptable coastal

30–40 — Good offshore comfort

Over 40 — Very comfortable offshore
