Renown 32 Westerly Performance

How the Renown 32 Westerly performs on the water — racing handicap, speed, sail-carrying power, stability and comfort.

+ Add to Compare

The Renown 32 Westerly is moderately powered for comfortable coastal cruising, with acceptable motion comfort for coastal passages.

Hull Speed

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

6.7 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 25.0′, the Renown 32 Westerly tops out around 6.7 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √25.0′ LWL = 6.7 kts

Performance Ratios

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

SA / Displacement
15.1
Moderate sail power — a capable coastal cruiser, not overpowered.
Comfort Ratio
28.5
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
1.76
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
6.7kts
S# (Speed Number)
1.6
Pounds/Inch Immersion
849lbs
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
28.5
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
Capsize Screening Formula
1.76
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° 2.5 3.2 3.6 3.7
Close Reach60° 3.1 3.9 4.3 4.5
Beam Reach90° 3.7 4.7 5.3 5.5
Broad Reach120–135° 3.5 4.4 4.9 5.1
Run150–180° 2.8 3.5 3.9 4.1
These are simplified estimates based on hull speed (6.7 kts), SA/D (15.1), 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 Renown 32 Westerly — based on sail area, ballast, and displacement characteristics.

Ghost
Sweet Spot
Reef
Heavy
0–7 kts 7–20 kts 20–28 kts 28+ kts
Ghosting
0–7 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
7–20 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
20–28 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
28+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
