1978 Islander Freeport Plan B

Listed
Expired
$55,000 USD

Seller's Description

The Islander Freeport 36 is a sea-kindly moderately heavy displacement masthead cutter with a modified full keel; have owned her since 2005 and converted her to a cutter rig by installing a removable inner forestay. The cabin sides have also been strengthened. She has the popular Plan B cabin arrangement, with head at the bow and a Pullman berth. There is a remarkable amount of cabin room and head height for a 36’ boat - once you see inside I promise you’ll be completely sold on the boat!

All lines have been brought to the cockpit for single-handing, which is largely how I have sailed her on the Chesapeake Bay, in Florida and the Bahamas. Perkins 4-108 diesel, under deck autopilot, wash-down pump, microwave, LED cabin lights, freezer and fridge, hot & cold water. Spares - Alternator, fresh water pump and starter motor. 2 large adjustable solar panels. PDQ Wifi finder. Dinghy davits. Dripless shaft. Predator 2000 generator. Life raft. Force 10 cabin heater. Morningstar solar controller.

Selling for health and age reasons. Need a quick sale so make a reasonable offer.

Calculations

Hull Speed
6.9 kn
Classic: 7.03 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

6.91 knots
Classic formula: 7.03 knots
Sail Area/Displacement
16.0
<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.
15.95
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
37.1
<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

37.06
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
365.2
>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
365.18
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
31.8
30-40: moderate bluewater cruising 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
31.76
<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
1.9
<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
1.87
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Beside the 2 layouts depicted here, there was also a rare center cockpit model.
