2005 International Marine West Wight Potter 19

Listed

Seller's Description

Well cared for and well found. Always sailed on fresh water, currently stored indoors. This famous little cruising design has been across the Atlantic and to Hawaii, but its also great on the urban lakes, Mille Lacs, Rainy in Voyageurs or even the Apostle Islands in Superior. On its custom trailer you can take it anywhere with a modest tow vehicle and even store it in your garage when you get home!

Lots of great gear, really too much to list here.

Please contact me for photos, a full equipment list, and/or any details or questions.

General Description: The West Wight Potter 19 is a recreational sailboat designed for easy trailer sailing, featuring a hard-chine hull, a lifting centerboard, and a fractional sloop rig. Known for its unsinkable design and ability to be rigged and launched quickly.

Designed by Herb Stewart based on a successful British design, over 1600 have been produced at it has a loyal fan base.

The West Wight Potter 19 is a recreational keelboat, with a hard chine hull, built predominantly of fiberglass, with wood trim. It has a fractional sloop rig, a spooned raked stem, a vertical transom, a transom-hung rudder controlled by a tiller, and a vertically lifting fin keel. It displaces 1,225 lb (556 kg) and carries 370 lb (168 kg) of ballast. It is equipped with closed cell foam flotation and is unsinkable.

The boat has a draft of 3.58 ft (1.09 m) with the lifting keel extended and 0.50 ft (0.15 m) with it retracted, allowing beaching or ground transportation on a trailer. The keel is retracted from the cockpit by a winch and fully retracts.

Can be rigged and launched from its trailer in 45 minutes and can also be single-handly rigged and launched. Cabin headroom is 55 inches.

A 2008 review by John Kretschmer noted, “while plenty of Potters have made impressive passages, most are sailed quietly on lakes, bays and coastline all over the country. Most importantly, they’re almost universally admired by the folks who own them, and for good reason.”

Equipment: Very well equipped, please contact me for a full list.

Calculations

Hull Speed
7.7 kn
Classic: 5.49 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

7.71 knots
Classic formula: 5.49 knots
Sail Area/Displacement
18.4
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.
18.44
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
30.2
<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

30.22
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
116.1
100-200: light

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
116.13
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
7.4
<20: lightweight racing 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
7.38
<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
2.8
>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
2.81
<2: better suited for ocean passages
>2: better suited for coastal cruising
