What is the Maple Leaf One Design's sail area to displacement ratio?

The Maple Leaf One Design has a Sail Area to Displacement ratio (SA/D) of 18.33. Values between 14–18 are typical cruising sailboats; 18–22 is cruiser/racer; over 22 is performance racing.

What is the Maple Leaf One Design's comfort ratio?

The Maple Leaf One Design has a Ted Brewer Comfort Ratio of 36.43. A ratio over 30 indicates good offshore comfort; over 40 is very comfortable offshore.

Is the Maple Leaf One Design safe for offshore sailing?

The Maple Leaf One Design has a Capsize Screening Formula value of 1.46. Values under 2.0 are considered acceptable for offshore sailing; under 1.8 is ideal.

What is the hull speed of the Maple Leaf One Design?

The theoretical hull speed of the Maple Leaf One Design is 6.56 knots, calculated from its waterline length.

How much does a Maple Leaf One Design weigh?

The Maple Leaf One Design has a displacement of 10,000.00 lb and a length overall (LOA) of 35.16 ft.

Who designed the Maple Leaf One Design?

The Maple Leaf One Design was designed by Sparkman & Stephens, first built in 1946.

Maple Leaf One Design Performance — PHRF Rating, Hull Speed & Sailing Characteristics

The Maple Leaf One Design is well-powered with enough sail area to move in light air, with a steady, comfortable ride offshore.

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 24.0′, the Maple Leaf One Design tops out around 6.6 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.

1.34 × √24.0′ 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

18.3

Powerful cruiser/racer — quick in light air, reef early when it pipes up.

Comfort Ratio

36.4

Good offshore comfort — steady enough for multi-day passages.

Capsize Screening

1.46

Below the 2.0 offshore threshold — acceptable for ocean passages.

Hull Speed

6.6kts

S# (Speed Number)

1.7

Pounds/Inch Immersion

671lbs

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

36.4

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

1.46

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°	2.7	3.4	3.8	4.0
Close Reach60°	3.3	4.1	4.6	4.8
Beam Reach90°	4.0	5.1	5.7	5.9
Broad Reach120–135°	3.7	4.7	5.2	5.5
Run150–180°	3.0	3.8	4.2	4.4

These are simplified estimates based on hull speed (6.6 kts), SA/D (18.3), 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 Maple Leaf One Design — based on sail area, ballast, and displacement characteristics.

Ghost

Sweet Spot

Reef

Heavy

0–6 kts 6–18 kts 18–26 kts 26+ kts

Ghosting

0–6 kts

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

Sweet Spot

6–18 kts

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

Time to Reef

18–26 kts

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

Heavy Weather

26+ kts

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