The Hunter Formula 28 is a spirited performance cruiser designed by Stephen Jones, known for its origins as an International Offshore Rule (IOR) Half Tonner. Built by the distinguished British firm Hunter Boats Ltd. from 1984 to 1987, this monohull was conceived to offer competitive club and regatta racing capabilities alongside the potential for coastal cruising. She earned a reputation as a fast half-tonner, positioned firmly in Hunter's line of more performance-oriented yachts during that era.

The creation of the Formula 28 in 1984 marked Hunter Boats' continued commitment to performance sailing, following their successful collaboration with designer Stephen Jones on models like the Formula One. Produced for a relatively brief period, ending in 1987, only 26 units of the Formula 28 were built. During this time, Hunter Boats was notable for its forward-thinking approach, incorporating advanced materials such as Kevlar in the standard laminates of some of their performance vessels, including the Formula 28. The original design of the fractional sloop rig included runners, a common feature on racing yachts of the period, though later modifications, such as the fitting of swept-back spreaders, could negate the need for them.

Sailing Performance and Handling

The Hunter Formula 28 was engineered for lively sailing, and its design ratios reflect its performance aspirations. With a Sail Area to Displacement Ratio (SA/Disp) of approximately 21.77, the Formula 28 boasts a generous sail plan relative to its weight, indicating excellent performance in lighter winds and the ability to accelerate quickly. Its Ballast to Displacement Ratio (B/D) of 43.4% suggests a stiff and stable boat, capable of standing up to a good breeze and maintaining its sail plan even when pressed. Furthermore, a Displacement to Length Ratio (D/L) of around 168.9 classifies the Formula 28 as a relatively light and performance-oriented boat for its length, contributing to its nimble handling and responsiveness. Anecdotal evidence confirms its status as a "fast half tonner racing yacht," designed to perform well in competitive club racing. Its balance in different sea states is generally praised, offering an engaging experience for those seeking a responsive and capable sailboat.

Accommodations and Layout

Reflecting its design as an IOR racer, the interior of the Hunter Formula 28, while designed for practicality, is typical of performance boats of its size and era. The vessel is equipped to provide sleeping for up to six individuals, indicating a functional layout suitable for crew on longer races or for weekend cruising. Given its emphasis on sailing performance and a beam of 8.2 feet, the interior likely prioritizes efficiency and essential amenities over expansive living spaces, focusing on maximizing performance on the race course while offering sufficient comfort for its intended use.
