1981 Island Trader Island Trader 46

Listed

Seller's Description

After over 35 years of owning numerous sailboats and doing ocean passages, my co-owner and I sought a comfortable vessel with which to cruise the ICW. We couldnt quite stomach the transition to a straight up trawler and found the Island 1981 Trader 46 motor-sailer the perfect fit. As hands-on boaters, bringing a 40-year-old boat up to Bristol standards was enticing. With this current passage and cruising the Florida coast this winter, we will have achieved our purchase objectives. We are now selling this comfortable classic for delivery some time in 2024 to a new custodian.

We purchased Whiskey River in July of 2022. She was lying in Punta Gorda, FL lightly used by the owner over the previous 3 years as a floating condo. She was not being well used or maintained.

While on the hard in Rock Hall, all exterior brightwork was taken down to bare wood and refinished with a minimum of 12 coats of Epiphanes High Gloss Varnish. Propeller and cutlas bearing were disassembled and inspected. Bow thruster inspected. All zincs replaced. Bottom cleaned and 2 coats of Interlux Micron CSC applied. The bowsprit was completely rebuilt. Water pump and VHF antenna replaced. Other major upgrades in 2022: New Ray Marine Axiom chart plotter and Quantum 2 Doppler radar, Pronautic 40 amp 3 bank battery charger, custom wood deck boxes, new curtains and cushion covers, rebuilt hydraulic steering piston, repacked rudder and prop shaft packing nuts, installed bonding wire to all through hull fittings, added secondary bilge pump, installed SparTite mast wedging and new mast boots, replaced and added various gauges, working on cleaning up and labeling all wiring.

While we have thoroughly enjoyed Whiskey River, it is time for us to move on. We seek a loving buyer who will appreciate her heritage, style, spaciousness, and comfort. The master suite and extensive storage make Whiskey River the ideal liveaboard.

Equipment: There were significant repairs and upgrades to the vessel over the 2015-2018 period. Work included: engine rebuilt (Ford Lehman 120), decks rebuilt, transom rebuilt, bottom job, bow thruster installed, fuel tank replaced with aluminum 128 gal., new 100 gal polyethylene water tank, new generator, new Xantrex battery charger, new water maker, new washing machine. 2 new heat pumps, new aft canvas/ss cockpit awning, secondary head installed, new (used) masts, chainplates, and new standing and running rigging.

Calculations

Hull Speed
7.8 kn
Classic: 7.85 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

7.83 knots
Classic formula: 7.85 knots
Sail Area/Displacement
13.0
<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.
12.97
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
27.2
<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

27.22
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
349.1
275-350: heavy

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
349.06
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
40.5
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
40.46
<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
1.7
<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
1.71
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Derived from the earlier HARDIN 45.
Built in Taiwan and finished in NJ, USA.
