Seller's Description

The Explorer 45, designed by Stan Huntingford, will bring you “a little peace, a lot of independence”. This vessel is an exceptional cruising boat of moderately heavy displacement with full keel offering a stable, sea kindly ride. There were approximately 30 made. Her design will give you standing stability in a heavy seaway. From the thick fiberglass hull to her warm interior, the Explorer 45 is a worthy, comfortable and safe blue water cruiser. She comes with a nice sail inventory: A spinnaker and pole, 2 main sails, 2 jibs, 2 staysails. A Vacuflush toilet system is included for you to install. An Alaskan stove/heater is included. The chimney is installed. There is an older working Ratheon Radar ready to be installed.

There is a huge cockpit with 3 large lazerette storage areas. The framework for a Bimini is also included. Sails are in storage and in good condition. Forward cabin features a V berth. Moving aft there long settee 6’6” to starboard and a dinette to port followed by a U-shpaed galley. Navigation center to starboard with full sized chart table and drawers, lockers under and book/electronics shelves on either side. Moving aft is a sea berth to starboard with engine access to port. Aft cabin has very large berths double and single crossing the width of the aft stateroom. Two enclosed heads one in aft cabin which does not have a head at this time. And one for use from salon or forward cabin. There is a very large storage area accessible from the cockpit and engine room. LOA 45 ft 5 in Length at Water Line 34 ft Beam 13 ft Max Draft 6 ft 8 in Displacement 30000 lb Water 200 gallons Fuel 175 (tank needs work as it has a leak) This sailboat is an excellent value and will be sold as is.

Calculations

Hull Speed
7.7 kn
Classic: 7.81 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

7.7 knots
Classic formula: 7.81 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
3.1
<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

3.13
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
363.8
>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
363.81
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
42.8
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
42.82
<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
1.65
<2: better suited for ocean passages
>2: better suited for coastal cruising
