Design Brief & Intent
The core mission of the Kite is to deliver a highly responsive, spirited sailing experience without sacrificing the classic aesthetic appeal of a traditional gaff-rigged vessel. In designing the Kite, Wolstenholme sought a more athletic, performance-oriented alternative to heavier, displacement-bound trailer sailers of the era, such as his own Norfolk Gypsy or the Cornish Shrimper 21. Weighing in at just 1,653 pounds, the Kite is roughly half the weight of those traditional competitors, making launch, recovery, and road transport vastly less demanding.
The interior design reflects a philosophy of elegant minimalism. It is not an expansive home-away-from-home, but rather a functional, shelter-focused cabin featuring two comfortable single berths, a designated space for a portable stove, a marine chemical toilet, and basic galley storage. Finished in satin white with varnished mahogany trim, the cabin feels light and airy, illuminated by oval portlights on the cabin sides and front.
On deck, the cockpit is deep, secure, and notably generous, comfortably accommodating a crew of four for day sailing. The cockpit is too deep to be self-draining, meaning water drains into a sump below the sole, but it features massive lockers including dedicated outboard engine and fuel storage designed to meet modern safety compliance standards.
Variations & Configurations
The Kite has been produced in two primary construction methods, each affecting the weight distribution and character of the boat. The early custom models were built using 9mm marine plywood sheathed in glass cloth and epoxy. These wooden versions are highly prized for their craftsmanship and represent a traditional, bespoke approach to the pocket cruiser class.
For the production version, Demon Yachts avoided simply taking a mold from the wooden hull. Instead, they utilized a vacuum-infused composite construction process consisting of vinyl ester resin, multi-axial fiberglass, and a closed-cell foam core. This high-tech build kept the GRP hulls identical in weight to the lightweight plywood originals while introducing slight, sophisticated styling adjustments, including a molded sheerstrake to visually lower the profile and softened curves along the coachroof.
Rigging configurations remain consistent across both builds: a deck-stepped gaff sloop rig utilizing lightweight carbon-fiber spars painted white, paired with a varnished spruce bowsprit. The carbon spars are incredibly light, allowing a single person to step the mast and rig the boat on a slipway in minutes. Below the waterline, the boat utilizes an internally lead-ballasted NACA-sectioned centerboard housed in a low-profile case and raised via a differential winch, alongside a balanced lifting rudder.
Sailing Performance & Handling
The physical handling characteristics of the Kite are defined by its specialized design ratios. With a displacement-to-length ratio of 112.85, the hull is classified as ultra-light. Rather than plowing through waves, the single-chine hull behaves like a large dinghy, skimming over the water with a clean release and showing a willingness to plane downwind. Under sail, it is exceptionally quick and highly sensitive to helm inputs.
A sail area-to-displacement ratio of 24.27 indicates a remarkably powerful sail plan. Thanks to the lightweight carbon spars, weight aloft is minimized, allowing the boat to maintain exceptional light-air performance. When the wind increases, the boat's hard chines provide rapid form stability, which, when combined with a ballast ratio of 25.89 percent, allows the Kite to carry its full mainsail and jib far longer than its light weight would suggest.
The capsize screening value of 2.28 and a comfort ratio of 9.98 confirm that the Kite is an active, sporty dayboat rather than a heavy-displacement, slow-motion passage maker. The helm remains light, balanced, and communicative. It handles short, steep coastal chops cleanly, keeping the cockpit surprisingly dry due to its flared bow sections and wide forward reserve buoyancy.
Modernization & Upgrades
Given the progressive, high-tech nature of the composite GRP builds, modern owners have actively embraced propulsion upgrades. The traditional outboard well, designed for a small petrol motor of up to 6 horsepower, is increasingly retrofitted with electric propulsion. High-efficiency electric outboards, such as Torqeedo or ePropulsion units, have become the standard upgrade. Because these motors use lightweight, removable lithium-iron-phosphate (LiFePO4) batteries, they align perfectly with the boat’s weight-saving ethos, eliminating the smell and weight of onboard petrol while dropping easily into the dedicated lockers.
For racing and performance optimization, some owners have secured IRC rating certificates, configuring the boats with hard-racing antifouling and adding carbon-fiber whisker poles to handle loose-luffed downwind sails. Long-term durability upgrades often focus on the centerboard winch mechanism, where owners sometimes replace original wire lines with high-tensile Dyneema to eliminate corrosion concerns inside the centerboard trunk.
Market Snapshot & Economics
The Kite occupies a highly niche, premium position in the brokerage market. Because they are hand-built in low production numbers by high-end yards like Demon Yachts or built as custom wooden commissions, they are incredibly scarce. They command a significant price premium compared to mass-produced trailer sailers of similar length, reflecting their carbon spars, advanced infusion construction, and design pedigree.
The economic model of owning a Kite, however, is highly favorable. Because the boat sits on a custom braked road trailer, owners can bypass expensive marina berthing fees, storing the boat at home during the winter and towing it to various sailing grounds with an ordinary family sedan. Refit economics are also low compared to larger cruising yachts; sails are small enough to be easily replaced, and there are no complex inboard diesel engines, through-hull plumbing networks, or heavy fixed keels to service.
The Verdict
The Wolstenholme Kite is an exceptional modern classic that successfully bridges the gap between traditional aesthetics and modern high-performance engineering. It is not a boat built for long-distance, offshore passage making or luxurious live-aboard comfort. Instead, it is a highly refined, exceptionally fast, and easily managed trailer-sailer designed for those who appreciate high-quality composite craftsmanship, dinghy-like sailing responsiveness, and the ability to explore shallow estuaries and coastal bays with ease.
- Exceptional sailing performance with sportsboat-like acceleration and light-air speed.
- Carbon-fiber spars minimize weight aloft and make single-handed rigging quick and simple.
- High-quality build options, featuring either bespoke epoxy-plywood or advanced vacuum-infused composite hulls.
- Extremely easy to trail, launch, and retrieve behind a standard family car due to its low dry weight.
- Highly efficient lifting centerboard and rudder allow access to shallow waters and worry-free beaching.
Cons
- Very limited cabin headroom and sparse amenities, making it suitable only for basic weekend camping.
- Extremely scarce on the brokerage market, requiring patience to acquire.
- Command a premium price point compared to average, mass-market trailer sailers.
- The deep cockpit is not self-draining, relying on a sump and bilge pump system.
