Seller's Description

This is a great trailer-sailer for daysailing, short overnights, single handing or cruising with friends and family. It features a unique ballasted shoal keel, so you can tuck into the shallowest of places. The drop-down centerboard provides stability and upwind performance that makes this boat safe and big fun to sail in a wide variety of winds. This boat is in very good condition and comes with extras. Long in production with much information available on-line. Length: 17.5 ft Beam: 7.5 ft Draft, Board up – 1’ 6” Draft, Board down – 4’ 3” Displacement – 1100 lbs. Ballast – 350 lbs Mast height above DWL – 27’ Designer: - Jim Taylor Sails - Main (85), jib (60) and spiniker (145, with pole) Tohatsu MFS 5 HP 2009 with alternator, low hours Continental trailer with tongue extension, guide posts and LED lights, 2009 tires almost always kept inside since then Shoal draft keel w/fiberglass center board Lead ballasted, self-righting design Kick-up fiberglass and aluminum rudder Laminated mahogany and ash tiller Stainless steel standing rigging Molded in non-skid deck surface 6’4” self bailing cockpit Fuel tank locker Cockpit seat locker Electrical system W/ navigation and cabin lights Sliding companionway hatch Cockpit lead halyards Cam cleats for jib Stainless steel bow rail, stern rail, stanchions and boarding ladder Stainless steel, kick up motor mount Stainless steel bow eye Teak wood trim 2 cabin windows with curtains Aluminum opening forward hatch with screen.

Calculations

Hull Speed
?

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

?
Classic formula: ?
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
?

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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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