Seller's Description
Go to Sailing Texas classifieds for current sailboats for sale Boston Whaler Harpoon 5.2 sailboat for sale LWL: 15’ beam: 7’5” Draft: 4-1/2” (board up) 3’8” (board down) Hull weight” 400 lbs. Sail area: main:108 sq.ft. jib: 52 sq.ft. (160 sq.ft. total)
Often termed “The Ultimate Daysailer” and “The Mercedes of dingies” this wonderful little sailboat can be easily rigged by one person, has a huge cockpit that can easily handle 4 or more crew and be towed by compact vehicles. Quick, very stable, and capable of reaching planing speeds on a broad reach. Just a blast to sail.
Self bailing cockpit both underway and at rest.
Built with the Boston Whaler unsinkable foam sandwich construction method, and designed by by the famous C&C yachts, this boat is in excellent condition, especially considering it’s age, and although titled as a ‘77 I suspect that it is a later build as it has the much more desirable solid mahogany benches instead of the earlier installed teak laminated plywood benches which tended to de-laminate.
The hull has zero damage, all fittings, standing and running rigging, sheets and halyards, Elvstrom bailers, foam filled Kenyon spars, and the original North sails are also in excellent condition.
An additional jib is also included. Zero issues with the retractable centerboard. The galvanized trailer has zero rust, newish bearings and new wheels and tires. The original Harpoon handbook, brochures, and additional information on the design and history are all included in the sale. The boat is located in Marble Falls, Texas

8.4 kn
Classic: 5.19 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
- Sail Area/Displacement
-
38.0
>20: high 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.
- 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
- Displacement/Length
-
74.8
<100: Ultralight
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
- Comfort Ratio
-
3.8
<20: lightweight racing 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
- Capsize Screening
-
3.6
>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
Notes
An open cockpit version was also available without the cuddy/cabin.
