Saga 36 Performance

How the Saga 36 performs on the water — racing handicap, speed, sail-carrying power, stability and comfort.

+ Add to Compare

The Saga 36 is modestly canvassed and unhurried, with a steady, comfortable ride offshore.

Hull Speed

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

7.1 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 28.3′, the Saga 36 tops out around 7.1 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √28.3′ LWL = 7.1 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
13.2
Modestly canvassed — a comfortable, unhurried cruiser.
Comfort Ratio
38.6
Good offshore comfort — steady enough for multi-day passages.
Capsize Screening
1.64
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed
7.1kts
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
38.6
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
1.64
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° 3.8 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 (7.1 kts), SA/D (13.2), 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 Saga 36 — based on sail area, ballast, and displacement characteristics.

Ghost

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.
