$145,000 USD

Seller's Description

Designed by Stan Huntingford and built by Canadian builder Cooper Yachts, the Maple Leaf 54 is a hand laid FRP cutter-rigged pilot house sloop. The modified fin keel with bulb ballast and skeg-hung rudder pairs nicely to make for a comfortable sail that handles well. The center cockpit with lower helm pilot house provides safe and comfortable options to stay dry or shaded from the elements. Then theres all the space that this boat offers… It might be an understatement to simply say the boat is spacious, sporting an aft Master Cabin, a guest Stateroom, and a Crew Cabin. The Salon will also easily accommodate a party of up to 6-10 people.

Some Highlights include:

Ford Lehman 120 6 cyl Diesel engine Top-end rebuild 2017. Generator- Kubota DC with 175 amp Ample alternator - Rebuilt 2019. Webasto forced air Diesel Heater. Water maker/Desalinator CruiseRO 30 gallons/hour purchased new in 2017. Bow Thruster with controls at the helm. Furling systems for all sails: The Genoa and Staysail on roller furlers & Mainsail is a Quantum sail on easy-furl by Forespar roller furling system. (3) 325 watt Canadian Solar solar panels for energy independence. Maxwell HWC15 electric Windlass -purchased new in 2017, with center cockpit controls. 40KG Rocha & 400 of 3/8 inch chain - more than enough to give peace of mind on the hook. SSB, RADAR, and an Iridium Go!

This Cooper Yachts Maple Leaf 54 is in excellent condition for her experience. The boat lived most of its life in the Pacific North West, and only recently cruised south with the current owners (the last 4 years). They are the 3rd owners of this vessel, and it has brought their family of five unforgettable memories on the water. Now it awaits a new adventure with new owners in the perfect location, Mexico!

Calculations

Hull Speed
10.7 kn
Classic: 9.01 kn

Hull Speed

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Formula

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL

10.65 knots
Classic formula: 9.01 knots
Sail Area/Displacement
14.8
<16: under powered

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

Formula

SA/D = SA ÷ (D ÷ 64)2/3

  • SA: Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D: Displacement in pounds.
14.83
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
28.6
<40: less stiff, less powerful

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Formula

Ballast / Displacement * 100

28.57
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
202.5
200-275: moderate

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

Formula

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet
202.47
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
36.7
30-40: moderate bluewater cruising boat

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Formula

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)

  • D: Displacement of the boat in pounds
  • LWL: Waterline length in feet
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet
36.7
<20: lightweight racing boat
20-30: coastal cruiser
30-40: moderate bluewater cruising boat
40-50: heavy bluewater boat
>50: extremely heavy bluewater boat
Capsize Screening
1.7
<2.0: better suited for ocean passages

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

Formula

CSV = Beam ÷ ³√(D / 64)

  • Beam: Width of boat at the widest point in feet
  • D: Displacement of the boat in pounds
1.72
<2: better suited for ocean passages
>2: better suited for coastal cruising
