The Harpoon 6.2 represents the flagship of Boston Whaler’s brief but high-quality venture into the sailing market between 1979 and 1983. While the builder is synonymous with powerboats, they applied their signature Unibond™ foam-core construction to this 20-foot "weekender" to create a vessel that was both unsinkable and remarkably stiff. Unlike the smaller dinghy models in the line, the 6.2 was designed by the C&C Design Group, a partnership intended to provide the boat with genuine performance pedigree that differentiated it from the more utilitarian "daysailer" competitors of the era. With a production run estimated at only 150 to 200 units, it has since become a rare find on the used market, prized for its combination of small-yacht features and trailerable convenience.

Sailing Performance & Handling

The Harpoon 6.2 was engineered for stability and ease of use, featuring a fractional 7/8 rig that prioritizes a large mainsail and a smaller, more manageable jib. This setup, often found on larger racing yachts, reduces the physical effort required for tacking. According to original marketing materials and technical data, the boat carries approximately 550 pounds of fixed lead ballast, contributing to a high level of righting moment for a boat of its size. Its Sail Area to Displacement (SA/Disp) ratio sits at a healthy 21.7, indicating a boat that is lively and capable in light air, though its relatively short waterline length of 15' 10" limits its theoretical maximum hull speed to approximately 5.3 knots.

Handling is characterized by the predictability one would expect from a hull designed by C&C. The boat tracks well thanks to its fixed fin keel—a departure from the centerboard designs of its smaller siblings—which provides a draft of 3' 6". While the 6.2 is not a dedicated sportboat, it was noted in period reviews to be significantly more stable than the lighter Harpoon 5.2, making it a preferred choice for families or those sailing in coastal waters where chop and higher winds are common. Owners frequently report that the boat feels "bigger" than its 20 feet, a result of the 8-foot beam which provides ample deck space and initial stability.

Interior Comfort & Variations

Despite its trailerable dimensions, the Harpoon 6.2 offers a surprisingly functional "weekender" interior. The cabin provides roughly 51 inches (4' 3") of headroom, which is generous for a boat that can be towed behind a standard vehicle. The layout typically includes a V-berth forward that can accommodate two adults, with molded-in storage compartments beneath the cushions. The interior aesthetic reflects the high standards of 1980s Boston Whaler production, featuring upholstered headliners, teak or mahogany trim, and designated areas for a portable head, a small stove, and a sink.

The cockpit remains the primary living space, designed to be self-bailing—a critical safety feature that allows the boat to be left on a mooring without fear of flooding during rain. The wide 8-foot beam ensures that the cockpit does not feel cramped even with four adults aboard. Storage is a high priority, with two large lockers under the cockpit seats designed to hold bulky items like fuel tanks and batteries. While the 6.2 was the largest in the series, it shared design DNA with the Harpoon 4.6 and 5.2, though those models were primarily open-cockpit daysailers and lacked the enclosed living amenities of the 6.2.

Known Issues & Buyer’s Checklist

The most critical area for any prospective buyer is the integrity of the foam-filled hull. Because Boston Whaler uses a closed-cell foam sandwich construction, the boat is theoretically unsinkable; however, if the fiberglass skin is breached or if through-hull fittings were not properly sealed by previous owners, water can migrate into the foam. This can lead to significant weight gain and, in extreme cases, delamination of the hull skins.

When inspecting a Harpoon 6.2, buyers should look for:

  • Deck and Hull Crazing: Like many boats from the early 1980s, the gelcoat on the Harpoon 6.2 is prone to "spiderweb" cracks, especially in areas of high stress like the mast step or deck-to-hull joints.
  • Hardware Backing: Because the boat is foam-filled, accessing the underside of deck hardware to replace or tighten bolts can be difficult. Check for any signs of movement in the cleats, winches, or pulpit.
  • Keel-to-Hull Joint: Ensure there is no significant "smile" or cracking where the fixed lead keel meets the fiberglass stub, as this can indicate past groundings.
  • Woodwork Maintenance: The mahogany seats and cabin trim require regular varnishing; if they have been neglected, they may require professional restoration or replacement to maintain the boat's value.

Community & Resources

The primary hub for technical support is the Harpoon Sailboat technical site, which hosts digitized copies of original brochures and rigging guides. For broader maintenance questions regarding the Unibond™ hull construction, the ContinuousWave forum is the definitive resource for Boston Whaler enthusiasts. Owners also frequently reference the C&C Design Group archives for historical context regarding the hull's performance characteristics.

The Verdict

The Harpoon 6.2 is a "gentleman’s daysailer" that successfully blends the safety of the Boston Whaler brand with the performance sensibilities of C&C Design. It is an ideal choice for the sailor who wants the security of an unsinkable hull without sacrificing the ability to spend a night at anchor.

Pros:

  • Unsinkable Unibond™ construction provides exceptional peace of mind.
  • High-quality deck hardware (Harken/Schaefer) was standard from the factory.
  • Large, self-bailing cockpit and 8-foot beam offer superior stability and comfort.
  • Trailerable and relatively easy to rig with a small crew.

Cons:

  • Very limited production run makes finding parts and specific sister-ship advice difficult.
  • Risk of water absorption in the foam core if the hull has been neglected.
  • The 3' 6" fixed draft limits access to very shallow "skinny water" anchorages.
  • A premium "Whaler" price tag is common on the used market compared to similar 20-footers.
