Seller's Description

The Mason 43 is an iconic, classic design, built to Lloyds of London standards for for fiberglass vessels. SOLITUDE has spent over half of her life, very lightly sailed for less than half of the year on the fresh water of the great lakes. she features the finest teak interior and has berths for as many as 9. She has received exceptional maintenance by a very meticulous owner including annual refreshing of the exterior teak. Now a change in life style makes her available to a new owner. The boat is cutter rigged and boasts an impressive list of upgrades and equipment, from the recently replaced Yanmar diesel engine, a 3 blade feathering prop, to other additions like a electric windlass, and bow thruster. Bulletproof is the word to describe the construction of the Mason 43.

MAIN SALON The main salon is wrapped in tongue and groove teak and has a large U-shaped dinette and settee to port which converts to a double berth. To starboard is a lower settee/pullout berth and an upper pilot berth can accommodate 4 crewmembers. There are storage lockers behind cushion-backed settees. All the upholstery has been refreshed and in excellent condition. Suspended above the teak dining table hangs a beautiful large brass ships lantern.

AFT STATEROOM The aft stateroom can accommodate 3 crew with a double berth to port and a single berth to starboard. There are storage lockers with louvered doors outboard of both berths. Another large storage locker is in between the berths. Extremely well ventilated with opening portlights on three sides.

FORWARD CABIN The forward cabin features a generous double vee berth and storage lockers on all sides including hanging lockers.The oversized glass overhead hatch provides plenty of light and additional ventilation. There is also access to the chain locker through forward bulkhead.

Calculations

Hull Speed
7.4 kn
Classic: 7.49 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

7.37 knots
Classic formula: 7.49 knots
Sail Area/Displacement
14.4
<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.
14.43
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
33.6
<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

33.6
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
365.2
>350: ultraheavy

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
365.15
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
39.0
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
38.96
<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
1.67
<2: better suited for ocean passages
>2: better suited for coastal cruising
