About the Maple Leaf 45

Built during the late 1970s, this Canadian-designed cruiser emerged from the creative minds at Maple Leaf Yachts as a serious bluewater sailing vessel. The Maple Leaf 45 represents the era's commitment to solid construction and traditional sailing characteristics, designed specifically for sailors seeking reliable offshore performance. With her generous beam and moderate displacement, this yacht strikes a thoughtful balance between interior comfort and sailing capability. The design prioritizes seaworthiness over speed, making her particularly well-suited for extended coastal cruising and ocean passages where dependability matters more than racing performance. Her robust fiberglass construction and conservative sail plan reflect the design philosophy of the period, emphasizing safety margins that inspire confidence in challenging conditions. The spacious cockpit and well-protected helm position demonstrate clear attention to crew comfort during long passages. While detailed specifications remain limited, the Maple Leaf 45 has earned respect among cruising sailors for her predictable handling characteristics and solid construction quality. This yacht appeals to sailors planning serious coastal exploration or considering their first ocean crossing, offering the kind of proven reliability that transforms ambitious sailing dreams into achievable adventures.

Comfort Ratio Ted Brewer's Comfort Ratio predicts how comfortable a boat will feel in offshore conditions. Higher values mean a steadier, more comfortable motion in a seaway.
Under 20 — Uncomfortably rough20–30 — Acceptable coastal30–40 — Good offshore comfortOver 40 — Very comfortable offshore

Capsize Screening Formula The USHS Capsize Screening Formula estimates offshore capsize risk. Lower is safer — values under 2.0 are considered acceptable for offshore sailing.
Under 2.0 — Safe for offshore2.0–2.2 — Borderline offshoreOver 2.2 — Coastal use recommended

Hull Speed Hull Speed is the theoretical maximum speed of a displacement hull, calculated from waterline length. Most cruising sailboats reach this speed in moderate conditions. 8.23
Pounds/Inch Immersion Pounds per Inch Immersion (PPI) tells you how much weight is needed to sink the boat one inch. Useful for calculating how additional gear and stores affect waterline. 1.0
