Configured so that everything can be operated from the cockpit. The engine, Westerbeke 13, has been refurbished with all new hoses and gaskets. Many parts sandblasted and painted. Has been running like a top for the last 4 years. Starts on first attempt. All water tanks have been removed and converted to storage. There is no septic tank. The kitchen and bathroom sinks run straight out the through hull. For the toilet, i use “Double doodie” camping bags that I drape over the toilet and dispose of at the end of each sail. Makes for a boat with zero septic odour. It’s quite nice. The cushions are in great condition. All cabin lights have been upgraded to fancy LED’s. It’s a gorgeous boat. Has an ice box and a two burner propane stove. Tons of storage space. Very comfortable, roomy cabin and cockpit.

She sail as good as she looks!

The teak is in amazing condition for a 42 year old boat. It’s been very well cared for.

Time for me to move on to a new project. She’s currently in the water. Likely hauling out at the end of October. Can be seen at the Nepean Sailing Club. Comes with many extra goodies.

Calculations

Hull Speed
7.2 kn
Classic: 6.62 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

7.23 knots
Classic formula: 6.62 knots
Sail Area/Displacement
16.1
16-20: good performance

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.
16.13
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
32.3
<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

32.34
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
261.0
200-300: 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
260.95
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
22.9
20-30: coastal cruiser

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
22.88
<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
2.1
>2.0: better suited for coastal cruising

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
2.06
<2: better suited for ocean passages
>2: better suited for coastal cruising
