Wanderer 30 Laurent Giles Performance & PHRF

The Wanderer 30 Laurent Giles is modestly canvassed and unhurried, with a gentle bluewater motion.

Hull Speed

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

6.6 kts

A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 24.5′, the Wanderer 30 Laurent Giles tops out around 6.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.

1.34 × √24.5′ LWL = 6.6 kts

Performance Ratios

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

SA / Displacement

9.9

Modestly canvassed — a comfortable, unhurried cruiser.

Comfort Ratio

54.6

Very comfortable in a seaway — a genuine bluewater motion.

Capsize Screening

1.43

Below the 2.0 offshore threshold — acceptable for ocean passages.

Hull Speed

6.6kts

Pounds/Inch Immersion

817lbs

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

54.6

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

1.43

Below the 2.0 offshore threshold — acceptable for ocean passages.

Under 2.0 — Acceptable for offshore

Over 2.0 — Coastal / protected waters

PHRF Fleet Position

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°	2.1	2.7	3.0	3.1
Close Reach60°	2.5	3.2	3.6	3.7
Beam Reach90°	3.1	3.9	4.4	4.6
Broad Reach120–135°	2.9	3.6	4.1	4.2
Run150–180°	2.3	2.9	3.3	3.4

These are simplified estimates based on hull speed (6.6 kts), SA/D (9.9), 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 Wanderer 30 Laurent Giles — based on sail area, ballast, and displacement characteristics.

Ghost

Sweet Spot

Reef

Heavy

0–8 kts 8–22 kts 22–30 kts 30+ kts

Ghosting

0–8 kts

Light air, motor-sailing likely. Need patience and a light genoa.

Sweet Spot

8–22 kts

Comfortable under full sail. Best speed-to-comfort ratio.

Time to Reef

22–30 kts

Time to shorten sail. Reef the main, swap to a working jib.

Heavy Weather

30+ kts

Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
