1978 Boston Whaler Harpoon 5.2

  • Description

Seller's Description

Designed by Sparkman Stevens boat designers. It’s tempting to compare the BOSTON WHALER HARPOON 5.2 to typical daysailers it makes more sense to stack her up against bigger more expensive cruising boats. All fresh water sailed.

Roomy cockpit provided by a 7’6” beam, that is larger than most cruising vessels two times her size! Made with highest safety standards out there, foam sandwich construction means UNSINKABLE! Self bailing cockpit even at rest through Elvstrom Bailers. Trailer for towing to your favorite spots. Clean and ready for new ownership. I was planning on sailing the boat for the 2024 season, but the mast step needed repair, so I ended up buying a different boat to sail and repair this one.

Equipment: Hull painted - 2024 Deck crazing filled, Deck painted with non-skid areas painted with non-skid paint 2024. Bottom painted with non-fouling 2024 Aluminum mast painted, new hardware 2024, new standing rigging from West Marine, New Running rigging from West Marine 2024. Mast step area repaired 2024, epoxied fiberglass with G-10 plate under mast contact area, New outboard bracket (wood) 2024, New seats fabricated using Sapele and marine plywood 2024, Rudder painted 2024, Tiller clutch added 2024, Bailers need new gaskets installed … available in box, not installed. North Sails inspected 2023, new Harpoon logo added to main, new window added to jib.

Rig and Sails

Auxilary power, accomodations, calculations.

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.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

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.

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 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.

Ballast / Displacement * 100

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.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

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.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

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.

CSV = Beam ÷ ³√(D / 64)

An open cockpit version was also available without the cuddy/cabin.

Owner's comments:

Classic Boston Whaler Harpoon 5.2 Sailboat (1978) with Cuddy, in excellent, original condition.  Purchased in 1988, we are the second owners.   Our boat has been lightly used, and garage stored. This boat is complete, with all of the standard Boston Whaler Harpoon 5.2 equipment; including: North Sails (main and jib), Kenyon mast and boom, Harken standing and running rigging, and Elvstrom self-bailers. The Deck Seats, Fore-Deck Cover, Center Thwart, and Outboard Motor Mount are made of solid Teak.  The Trailer is a Calkins (Hot Dip Galvanized) with 5.30-12” tires, Bearing Buddies, and dolly. The Rudder/Tiller and Keel are original, and are in great condition. The outboard is a 4 HP Evinrude, Long Shaft (1985) with remote tank and teak tank holder.  For Trailering, we have a solid mahogany crutch (mast and boom), and a forward mast holder on the trailer.

This 17' Daysailer has a 7'-6" beam, Draft of 4.5”/44” and 160 square feet of sail. The Harpoon 5.2 is stable and fun to sail.  It is perfect for the individual sailor or a family.  With its roomy cockpit, the boat comfortably and safely seats four.  The Cuddy keeps your belongings dry and out of the way.  Designed by C&C Yachts and built by Boston Whaler, the Unsinkable Harpoon 5.2 has been referred to as the "Mercedes of Dinghies".

The magazine, Small Craft Advisor , published a wonderful review of this great boat in January, 2017, Edition # 103. You can also find the original Boston Whaler Harpoon 5.2 brochure with full specs and other details on the Unofficial Harpoon Website (Ruach.net) .

The boat is stored at our home in central New Jersey.

In 2017 we downsized from the Harpoon 5.2 to a new Melonseed from Crawford Boat Works.
