The Hallberg Rassy 49 is moderately powered for comfortable coastal cruising, with a gentle bluewater motion, and respectable in club racing.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 41.0′, the Hallberg Rassy 49 tops out around 8.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √41.0′ LWL = 8.6 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
PHRF Rating
120s/nm
Cruiser/racer — competitive in club racing, comfortable cruising.
SA / Displacement
17.3
Moderate sail power — a capable coastal cruiser, not overpowered.
Ballast / Displacement
45.1%
Race-oriented ballast ratio — very stiff and powerful.
Displacement / Length
257
Moderate-heavy — carries provisions well, deliberate in light air.
Comfort Ratio
40.1
Very comfortable in a seaway — a genuine bluewater motion.
Capsize Screening
1.70
Below the 2.0 offshore threshold — acceptable for ocean passages.
SA/Disp (Calculated)
13.5
Computed from measured I/J/P/E rather than reported sail area.
Pounds/Inch Immersion
13lbs
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
40.1
Very comfortable in a seaway — a genuine bluewater motion.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
1.70
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters

These are simplified estimates based on hull speed (8.6 kts),
SA/D (17.3), 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.

Sweet Spot
7–22 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
22–32 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
