1973 Islander Yachts I36

Listed
Expired
$49,900 USD

Seller's Description

Well maintained with many upgrades I36 currently used as a liveaboard. Has all the necessary equipment for long term cruising to Mexico or in the islands. Fully self sustainable. Also for sale is the mooring located in Newport Beach. Will sell boat and mooring as a package for 95k. This was my first boat and a lot of care, thought and work has been put into this boat. I am selling for the purpose of upgrading to a larger cruising vessel now that I have experience in and knowing what I need and want. All she really needs is exterior cosmetics a hull polishing/paint and non-skid deck.

Calculations

Hull Speed
7.7 kn
Classic: 7.12 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

7.73 knots
Classic formula: 7.12 knots
Sail Area/Displacement
16.3
16-20: good performance

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.
16.29
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
43.3
>40: stiffer, more 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

43.27
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
266.4
200-275: moderate

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
266.39
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
27.2
20-30: coastal cruiser

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
27.15
<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
1.88
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

With nearly 800 boats built this was one of the most successful models from Islander Yachts.
During it’’s production history the ISLANDER 36 was delivered with the following engines (in a an approximate cronological order):

Universal Atomic 4 -Gas
Palmer P-60 - Gas
Perkins 4-108 - Diesel
Westerbeke L-25 - Diesel
Pathfinder - Diesel
Yanmar - Diesel

It is said that the molds for the ISLANDER 36 were purchased by Newport Offshore Yachts of CA, USA in 1986. But it is not known if any other boats were built after this date.

SHOAL DRAFT: 4.8’/1.46m

TALL RIG:
I(IG):47.00’ / 14.33m
J: 14.48’ / 4.41m
P: 41.30’ / 12.59m
E: 12.80’ / 3.90m
