Seller's Description

If you are looking for an easy versatile sailboat that is easy to single hand or include a crew with the comfort you have found it with this 1983 Person 303.

This sailboat plan is a great daysailer or long weekender that is spacious on deck as well as below.

Relax in comfort and cruise with good visibility while positioned in the spacious cockpit even with the wheel mount helm there is room to move about.

The Islander 30 MK II can accommodate a single handler with ease or a family for a weekend venture cruising the coastline and exploring the intimate coves for an overnight anchorage.

Below there is 6-foot headroom, the galley is well-equipped. The well-insulated 5-cubic-foot icebox that drains to the bilge. The sink is serviced by both pressure and foot-operated freshwater pumps and there is a two-burner stove and oven for cooking. There is a good-sized quarter berth opposite the galley that stretches aft. Port and starboard settees in the saloon have removable seatbacks that allow them to be converted into comfy berths for sleeping. A dining table folds down from the starboard bulkhead and has a leaf that extends to the port bench to allow seating for four.

There is a large head with a handheld shower, sink and toilet. The forward cabin has a large v-berth and a small bureau next to it

Calculations

Hull Speed
7.2 kn
Classic: 6.75 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

7.24 knots
Classic formula: 6.75 knots
Sail Area/Displacement
15.7
<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.
15.72
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
34.7
<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

34.66
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
276.4
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
276.41
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
23.9
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
23.9
<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
2.0
>2.0: better suited for coastal cruising

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
2.02
<2: better suited for ocean passages
>2: better suited for coastal cruising
