Seller's Description

1982 Boston Whaler Harpoon 5.2 Sailboat

Open cockpit, Boston Whaler Harpoon 5.2 no cuddy up front to get in the way and allows any passengers to be out of the way up front of the mast as you can see from the first picture taken just after starting of. this boat was made during the last years of their production when the folks at BW knew what they were doing. It sails on a puff of wind.

Complete boat, tow, launch and sail as is

Original North Sails sails.

Newish OEM rub rail, Boston Whaler spec motor mount I haven’t used the motor mount in 15 years. . I replaced and re-gelcoated the bailers then too and they are ship shape without leak or rot when closed and self bail when open and underway. The wood is original and complete and functional as what I use for sailing these last few years but some elbow grease and varnish to make nice trailer is 1997 load rite with a latch to elevate the fore part and allow launching and re-trailering without having to put much of the rim, let alone the hubs in the water. tires new summer 2023

I launched the boat in the spring to bring to my lift and took it out in the fall for the winter so trailer was in water a couple of dozen times since I got it The boat was only in the water when it was being used and moving

I bought this boat in 2002 after looking for one for years & love it. I am unexpectedly moving to a new location and realize I really won’t be able to use it. It deserves a good home

Honestly, if you don’t know the BW Harpoon 5.2 sailboat, do a web search to see why a 40 year old 17 foot sailboat is still a much sought after boat.

if you’ve been looking for a BW harpoon, this one is ready to go. let’s make a deal

Calculations

Hull Speed
?

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

?
Classic formula: ?
Sail Area/Displacement
?

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: under powered
16-20: good performance
>20: high performance
Ballast/Displacement
?

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

?
<40: less stiff, less powerful
>40: stiffer, more powerful
Displacement/Length
?

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
?
<100: ultralight
100-200: light
200-300: moderate
300-400: heavy
>400: very heavy
Comfort Ratio
?

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
?
<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
?

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