$25,000 USD

Seller's Description

Just price reduced April 27,2022! Very clean - review the “Equipment” section for recent updates. Call now for more details!

The Island Packet 27 is a recreational keelboat, built predominantly of fiberglass, with teak wood trim and a teak and holly cabin sole. It is a Cutter-rigged sloop, with a spooned raked stem , a vertical transom, a keel-mounted rudder controlled by a wheel and a fixed long keel or optional long keel and centerboard. It displaces 8,000 lbs and carries 3,000 lbs of ballast.

The keel-equipped version of the boat has a draft of 3.70 ft.

The boat is fitted with a Japanese Yanmar diesel engine of 18 hp. The fuel tank holds 19 U.S. gallons and the fresh water tank has a capacity of 31 U.S. gallons.

The mainsheet traveler is on the rear taffrail. The cockpit features two jib winches and two halyard winches. The cockpit has room for eight adults and includes an icebox. There is a bowsprit with an anchor roller.

The galley is located on the port side of the boat and includes a two-burner alcohol-fired stove and optional pressure water supply. The head is located just aft of the forward “V”-berth, on the starboard side. Additional sleeping accommodation is provided by a cabin settee, which converts to a double berth, plus a single berth to port. The cabin table folds up against the bulkhead.

Cabin ventilation consists of six opening ports and a forward hatch.

Calculations

Hull Speed
7.3 kn
Classic: 6.6 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

7.3 knots
Classic formula: 6.6 knots
Sail Area/Displacement
16.2
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.
16.2
<16: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
37.5
<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

37.5
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
250.6
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
250.6
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
21.5
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
21.5
<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
2.1
>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
2.1
<2: better suited for ocean passages
>2: better suited for coastal cruising

Notes

Centerboard Model - draft: BU-2.67’/.81m; BD-6.0’/1.83m.
