Edel Cat 43 Performance

How the Edel Cat 43 performs on the water — racing handicap, speed, sail-carrying power, stability and comfort.

+ Add to Compare

The Edel Cat 43 is aggressively canvassed for its weight, with a quick, snappy motion best suited to day sailing.

Hull Speed

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

8.1 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.

SA / Displacement
30.1
Performance-oriented — carries a lot of canvas for its weight.
Displacement / Length
145
Ultralight — responsive and fast, but carries less stores.
Comfort Ratio
8.7
Quick, snappy motion — better for day sails and racing than long passages.
Capsize Screening
3.96
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
Hull Speed
8.1kts
Pounds/Inch Immersion
19lbs
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
8.7
Quick, snappy motion — better for day sails and racing than long passages.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
3.96
Above the 2.0 offshore threshold — best suited for coastal and protected waters.
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° 3.8 4.8 5.4 5.6
Close Reach60° 4.6 5.8 6.5 6.8
Beam Reach90° 5.6 7.1 8.0 8.6
Broad Reach120–135° 5.2 6.6 7.4 8.0
Run150–180° 4.2 5.3 5.9 6.1
These are simplified estimates based on hull speed (8.1 kts), SA/D (30.1), 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 Edel Cat 43 — based on sail area, ballast, and displacement characteristics.

Ghost
Sweet Spot
Reef
Heavy
0–5 kts 5–16 kts 16–24 kts 24+ kts
Ghosting
0–5 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
5–16 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
16–24 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
24+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
