Walstead 42 Performance

How the Walstead 42 performs on the water — racing handicap, sail-carrying power, stability and comfort.

+ Add to Compare

The Walstead 42 is moderately powered for comfortable coastal cruising, with a steady, comfortable ride offshore, and competitive on the racecourse.

Hull Speed

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

7.7 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 32.8′, the Walstead 42 tops out around 7.7 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √32.8′ LWL = 7.7 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
78s/nm
Performance racer — quick around the cans and offshore.
SA / Displacement
16.6
Moderate sail power — a capable coastal cruiser, not overpowered.
Ballast / Displacement
43.3%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
278
Moderate-heavy — carries provisions well, deliberate in light air.
Comfort Ratio
34.4
Good offshore comfort — steady enough for multi-day passages.
Capsize Screening
1.74
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
7.7kts
S# (Speed Number)
1.9
Pounds/Inch Immersion
1lbs
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
34.4
Good offshore comfort — steady enough for multi-day passages.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
1.74
Below the 2.0 offshore threshold — acceptable for ocean passages.
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° 3.0 3.8 4.3 4.4
Close Reach60° 3.7 4.6 5.2 5.4
Beam Reach90° 4.5 5.7 6.3 6.6
Broad Reach120–135° 4.1 5.2 5.8 6.1
Run150–180° 3.3 4.2 4.7 4.9
These are simplified estimates based on hull speed (7.7 kts), SA/D (16.6), 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 Walstead 42 — based on sail area, ballast, and displacement characteristics.

Ghost

Heavy
0–7 kts 7–22 kts 22–32 kts 32+ kts
Ghosting
0–7 kts
Light air, motor-sailing likely. Need patience and a light genoa.
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
32+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
