Manufacturer Provided Description

Maximum efficiency and comfort has been built into the interior of the Hunter 31. The forward cabin is larger than those in most boats of this class, achieved by adjusting the forward hull shape without affecting performance. A private aft cabin is also provided on the Hunter 31, along with an enclosed head with vanity and shower. The galley has an icebox, two-burner stove and stainless steel sink. Designer fabrics run throughout the Hunter 31, and the interior layout is clean and streamlined. You’ll love the Hunter 31’s seakindly handling as well. The computer-designed, solid fiberglass hull is the result of extensive testing and special engineering. Hunter designed the 31 considering both the weights of a small 1-2 person crew and larger 8-10 person crew with gear to insure low drag efficiencies under a variety of load and wind conditions. Henderson says the balanced spade rudder they designed for the 31 has good clean flow over foil sections, and helps make the boat fast and fun to sail. Hunter continues its concept of low maintenance exteriors with its all fiberglass deck. The cockpit is roomy and features a Lewmar Direct Drive steering system, optional folding wheel, hot/cold transom shower and a stern rail with Flexiteek seats. Rigging

Hunter’s proven easy-to-sail B & R fractional rig system consists of a Selden anodized mast, large roach mainsail with flaking system, dual single-line reefing, and jib furling. The furling sail has been designed to retain the sail area typically lost over a standard mainsail, and in fact has two more square feet than the 31’s standard sail. Hunter’s famous arch-mounted mainsheet traveler is an available option, along with a helm sheeting package that allows control of jib sheets from the back of the boat. Disclaimer

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
