1980 Bruce Roberts Mauritius 43/44

Listed

Seller's Description

This is an exceptional bluewater sailer built after the Bruce Roberts Design Mauritius 43/44 currently moored in Honolulu, HI. This is a wonderful boat for family, couple or single cruising enthusiasts. This boat was once a real beauty, but now is in need of restoration. She is a project boat which is still fully sailable.

The beauty of this boat is how comfortable she sails and is an easy live aboard. Large engine room, 2 heads (one with shower). A good size galley for the cooking aficionado consisting of a 3-burner stove top, good size oven, (currently needs a temperature sensor). The interior is a beautiful hardwood and the carpentry is by a master craftsperson. There is plenty of storage.

The hull is sound, bottom of boat was inspected and refinished with WEST MARINE CPP Ablative Antifouling Paint with CCT in 2021. Exterior above the waterline needs restoration and paint. The windows need updating, forward head needs extensive restoration and the refrigeration has been removed, (but there is a great place for a new system). Floors could use a refinish. All lines run through cockpit for ease of sailing.

This vessel is a registered coast guard vessel. She has sailed up and down the Pacific west coast of the US, the north sea and the Atlantic to Florida. For further information or to schedule a showing, contact owners at svmistley1980@gmail.com

Equipment: 4 person liferaft, misc parts, fittings, tools, computer with navigation software, full galley of dishes, silverware, pots and pans, games, library of sailing and navigation books, handheld GPS, on board navigation system both inside and in cockpit, auto-pilot, sails, anchors. All records have been kept in binders for easy reference along with complete plans of the vessel. The electrical system has been upgraded and coveted from 220 to 110.

Calculations

Hull Speed
7.6 kn
Classic: 7.64 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

7.62 knots
Classic formula: 7.64 knots
Sail Area/Displacement
?

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.
?
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
29.2
<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

29.16
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
349.2
275-350: heavy

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
349.16
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
37.9
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
37.93
<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
1.73
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

The MAURITIUS 43 is probably the most popular Bruce Roberts design. It is said that nearly 2000 yachts have been built to basic set of plans. Rig types vary. A flush deck version is called the NORFOLK 43.
