Seller's Description

CURRENTLY IN MARTINIQUE

An experienced bluewater Sea Wolf owned by experienced bluewater cruisers. This 40’ sailer is set up to cruise the oceans and see the world.

The Hardin is a Ketch design with a long keel and a keel-hung rudder. She makes her home on the islands and when she is in the States, she is moored in Panama City, FL. The boat has made two tours in the Caribbean, is currently sailing the East Caribbean and can be shown to potential buyers while there!

The Sea Wolf is set up for long hauls away from electrical connections and to handle unplanned eventualities. Two solar panels and the wind generator charge the batteries and the generator is used for A/C power when needed.

The Hardin is a sailor’s sailer. The boat is outfitted with Furuno GPS, two VHF radios, and a long-range SSB radio. Raymarine autopilot, depth sounder, and a Monitor wind instrument are at the helm. The cockpit is prepped for heavy weather with its hardtop dodger and windshields.

Sails onboard are the roller furling headsail, the mainsail with two reefpoints, and the mizzen sail. Ground tackle includes two anchors, one with 160’ chain and the other with 100’ chain. A windlass is at the bow.

The boat can sleep up to 6 or 7 depending on how it’s configured, with its V-berth, two double berths, and one single berth/settee. One of the double berths is converted for storage use at the moment and sleeps one. The full galley on this great boat includes a Force 10 oven and stove and a refrigerator/freezer. And, the dinette is positioned close to the cabin companionway for great crew access.

The owner is including a SailRite sewing machine which is onboard the boat and can handle sail and canvas work.

Calculations

Hull Speed
7.4 kn
Classic: 7.58 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

7.35 knots
Classic formula: 7.58 knots
Sail Area/Displacement
14.6
<16: under powered

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.
14.58
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
33.9
<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

33.93
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
381.9
>350: ultraheavy

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
381.9
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
44.4
40-50: heavy bluewater 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
44.42
<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
1.6
<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
1.6
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

SEA WOLF 40 is the name of the original Garden design built under the supervision of Bill Hardin at the Ta Chiao yard in Taiwan. A number of copies were built by different yards in Taiwan under a number of other names. These include: SEA TIGER 41, CT41, ISLAND TRADER 41, TRANSWORLD 41, CLIPPER 41, ATLANTIC CLIPPER 41 etc.
