The Hotfoot 31 is a rare and spirited performance cruiser designed by the Canadian naval architect Doug Hemphill and produced in limited numbers by the British Columbia-based yard Hotfoot Boats. Building on the significant regional success of the Hotfoot 27, the 31-foot model was conceived as a larger, more offshore-capable evolution of Hemphill’s "fast-is-fun" philosophy. Launched in the mid-1980s, the design targeted sailors who demanded the agility of a racing dinghy within the envelope of a cruiser. With only approximately 11 units ever produced, it remains a "sleeper" in the Pacific Northwest racing scene, often outperforming much newer designs in light to moderate conditions.

Sailing Performance & Handling

The Hotfoot 31 is defined by its exceptional power-to-weight ratio. With a displacement of only 5,000 lbs and a Sail Area/Displacement (SA/D) ratio of roughly 25.3, the vessel is categorized as a high-performance racer-cruiser that excels in light air. Its fractional rig, featuring a large mainsail and relatively small headsails, makes the boat exceptionally easy to tack, a characteristic praised in technical retrospective pieces found in Issuu - A Tale of Resurrection.

The Displacement/Length (D/L) ratio of 127 classifies the Hotfoot 31 as a light racer. In practice, this means the boat is highly responsive and can reach its theoretical hull speed of 6.8 knots with very little effort. However, the high SA/D ratio suggests that the boat is "overrigged" for heavy weather; owners often report the need to reef the main earlier than on more conservative cruisers to maintain control. The 40% ballast-to-displacement ratio provides a surprising amount of stiffness once the deep fin keel (drawing 6.0 feet) bites, but the boat’s low Motion Comfort Ratio (approximately 12.1) indicates it will be lively and somewhat "jittery" in a sea state compared to heavier displacement cruisers.

Interior Comfort & Variations

While the Hotfoot 31 was born from a racing pedigree, the interior was designed to accommodate coastal cruising for a small family or racing crew. Unlike the more Spartan racing-specific hulls sometimes found in this size bracket, the Hotfoot 31 typically features standing headroom and a traditional layout. The cabin is usually finished in light-colored woods like ash or teak to mitigate the feel of the relatively narrow 10.5-foot beam.

The layout generally includes a V-berth forward, followed by a head and a main salon with opposing settees. The galley is typically positioned near the companionway for ventilation, with a quarter berth tucked under the cockpit on the port or starboard side. Some variation exists among the few hulls produced, as several were sold as "owner-finished" kits. This led to a disparity in fit and finish between factory-completed boats and those finished in backyards, with some units prioritizing "pipe berths" and weight savings for racing, while others feature full cabinetry and pressurized water systems.

The Hotfoot 31 had a notable sibling variant known as the Hotfoot 30. This model was a modified, slightly shortened version of the 31-foot hull specifically designed to fit within the Midget Ocean Racing Club (MORC) maximum length requirements of the era. Other siblings in the Hemphill lineage include the legendary Hotfoot 27 and the smaller Hotfoot 20, the latter of which eventually saw its molds sold and modified to become the highly successful Ultimate 20.

Known Issues & Buyer’s Checklist

Prospective buyers of a Hotfoot 31 should approach the vessel with an understanding of 1980s fiberglass construction techniques.

  • Deck Core Saturation: Like many boats of this era built in the Pacific Northwest, the Hotfoot 31 often utilized balsa wood coring in the deck and cabin house. Inspections should focus on areas around stanchion bases, chainplates, and the mast step. Soft spots or elevated moisture readings are common and often require significant "drill and fill" or core replacement.
  • Keel-to-Hull Joint: The deep fin keel exerts significant leverage on the hull grid. Buyers should inspect the "smile" at the leading edge of the keel-to-hull joint for signs of movement or impact damage. High-performance sailing in heavy weather can stress this area, especially on boats that have been campaigned hard.
  • Rudder Bearings: The spade rudder is a high-aspect design that can develop play in the bearings over decades of use. Excessive vibration or "clunking" when the boat is loaded up on a reach often indicates that the rudder post bushings require replacement.
  • Rigging Tension: Because the boat is fractional and carries a significant amount of sail, the standing rigging—specifically the forestay and shrouds—must be kept in high tension to maintain mast straightness. Chainplate seals are a known weak point and should be checked for leaks that could rot the bulkheads below.

The Verdict

The Hotfoot 31 is an uncompromising choice for the sailor who values performance and West Coast design history over voluminous interior space. It is a rewarding boat for a skilled hand but may be intimidating for a novice in a breeze.

Pros:

  • Blistering light-air performance; often the fastest boat in its class during summer regattas.
  • Nimble handling and easy tacking due to the fractional rig.
  • High-quality Doug Hemphill design with a strong regional following and pedigree.

Cons:

  • Requires early reefing; can be "tender" and physically demanding in heavy air.
  • Extremely limited production makes finding parts or a sister ship for comparison difficult.
  • Lightweight construction leads to a "busy" motion in choppy water, which may cause fatigue on longer passages.
