Design Brief & Intent 4
The Hullmaster 22 was conceived as a highly trailerable weekend cruiser and spirited daysailer, engineered to fit on a standard road trailer while providing practical accommodations for a couple or small family. Within the Hullmaster lineup, this model was a major departure. Roy Brooks’ yard was primarily known for constructing heavy-displacement, traditional cruising yachts like the Ted Brewer-designed Hullmaster 27 and Hullmaster 31. While those larger sister ships were deep-keeled, blue-water passage-makers designed to cross oceans, the Hullmaster 22 was designed as a nimble, light-displacement boat optimized for shoal waters, inland lakes, and coastal bays.
In comparison to major competitors of its era, such as the Catalina 22, the Hullmaster 22 was built with a heavier focus on laminate thickness and structural stiffness. Hullmaster did not skimp on fiberglass, resulting in a solid, resilient hull that could easily withstand the high-frequency, short-period chop characteristic of the Great Lakes and Saint Lawrence Seaway.
The interior design maximizes the vessel's narrow beam with a clean, low-maintenance single-piece molded fiberglass liner. While headroom is limited to seated comfort—averaging around five feet—the layout is highly functional. The joinery features teak or mahogany trim, providing a warmer, more traditional aesthetic than many of its purely utilitarian contemporaries.
Variations & Configurations
The standard and most common configuration of the Hullmaster 22 features a masthead sloop rig paired with a shallow stub keel containing a retractable cast-iron centerboard. This setup offers a highly functional compromise for trailer-sailing. With the centerboard fully raised, the boat draws just 1.67 feet, allowing it to navigate shallow gunkholes, enter skinny channels, and easily glide onto a beach or trailer. When the centerboard is lowered, the draft plunges to 6.00 feet, transforming the boat into a weatherly, high-pointing performer with an exceptionally deep, high-aspect foil.
The sail plan is a robust masthead sloop rig with aluminum spars and a transom-hung rudder controlled by a tiller. While the vast majority of Hullmaster 22s utilized this centerboard layout, a rare fixed-fin keel variant with an internal spade rudder was produced under the sister North Star 22 line. This fixed-keel version eliminated the maintenance complexities of a centerboard trunk but sacrificed the easy launching and shoal-water versatility that made the centerboard model famous.
The interior layout remains uniform across variants, featuring a traditional four-berth arrangement. This includes a double V-berth in the bow, two single settee berths extending aft under the cockpit seats, a rudimentary slide-out galley drawer, and a dedicated space for a portable head tucked beneath the forward berth.
Sailing Performance & Handling
With a Sail Area to Displacement ratio of 19.39, the Hullmaster 22 carries a generous amount of canvas for its size. This makes the boat surprisingly responsive and agile in light summer breezes, allowing it to accelerate quickly and tack efficiently when lighter, modern daysailers might struggle to find drive.
However, its Displacement to Waterline Length ratio of 132.46 classifies it as a light-displacement vessel. This light weight, combined with a Motion Comfort Ratio of 11.3, means the boat’s motion in a heavy chop is lively and active. Rather than slicing through a head sea, the hull tends to ride over the waves, which can result in a quick, energetic, and sometimes wet ride.
The boat carries a Ballast to Displacement ratio of 37.95%, representing 835 pounds of cast-iron ballast situated low in the stub keel and centerboard. While this provides decent initial stiffness, the Capsize Screening Ratio of 2.33 indicates a relatively wide beam and high center of gravity relative to its overall weight. Because this ratio exceeds the offshore safety limit of 2.0, the Hullmaster 22 is strictly a coastal, lake, and protected-water cruiser with lower ultimate self-righting capability if knocked down.
Under sail, the boat tracks beautifully with the centerboard down, but as the breeze rises to 12 or 15 knots, the wide hull heels quickly. Early reefing is essential to maintain helm balance and prevent the transom-hung rudder from stalling or developing excessive weather helm.
Known Issues & Triage
The primary concern for any prospective buyer of a Hullmaster 22 centers on the retractable keel mechanism. The cast-iron centerboard is highly susceptible to rust and scale expansion, especially if the boat has been used in saltwater without diligent anti-fouling maintenance. If left untreated, the iron can swell to the point where it jams tightly inside the fiberglass centerboard trunk. Additionally, decades of use will inevitably wear down the pivot pin and its mounting bushings, resulting in a loud and annoying "keel clunk" as the boat rolls at anchor. Prior to purchase, the lifting cable, its winching hardware, and the pivot assembly must be thoroughly inspected and replaced if worn, as a cable failure can drop the heavy iron board catastrophically, cracking the fiberglass trunk.
Deck core integrity is another classic issue for Hullmaster yachts of this vintage. The deck construction uses a balsa-wood core sandwiched between fiberglass layers. Water penetration through poorly sealed deck hardware, such as chainplates, stanchions, cleat bolts, and the mast step, will rot the balsa core over time, creating soft, spongy spots on deck. Rig compression on the masthead sloop can also cause the deck to sag or compress around the mast partner if the core underneath is wet.
The transom-hung rudder also requires structural scrutiny. The pintles and gudgeons that secure the rudder to the transom are subject to significant torsional stress. Over time, the mounting holes can wallow out, causing loose or vibrating steering, and the rudder blade itself must be checked for water intrusion, internal delamination, and blistering.
Modernization & Upgrades
Modern owners of the Hullmaster 22 frequently focus on drivetrain and electrical upgrades. The boat was originally designed to carry a small outboard motor, typically in the 4 to 6 horsepower range, mounted on a transom bracket 4. Many owners are choosing to replace older, noisy two-stroke outboards with modern four-stroke long-shaft models, which help prevent the propeller from cavitating when the stern rises in a chop. Increasingly, owners are converting to electric outboards, which are highly efficient given the boat’s light weight. These systems are often paired with a house bank of lithium-iron-phosphate batteries secured low in the cabin sole to double as excellent low-slung ballast.
Rigging updates are also common. Given the age of these vessels, replacing the original wire standing rigging is a safety priority. Some owners upgrade to synthetic Dyneema shrouds to save weight aloft, which directly improves the boat’s tenderness. Adding a simple, removable bowsprit is a popular modification that allows the boat to fly an asymmetrical spinnaker, significantly boosting off-wind performance in light air.
Finally, rewiring the basic factory DC system is standard. This typically involves installing a modern fused electrical panel, transitioning all cabin and navigation lights to low-draw LEDs, and mounting a small solar panel on the companionway hatch garage to keep the batteries topped off.
Market Snapshot & Economics
On the brokerage market, the Hullmaster 22 is positioned as an evergreen, highly economical entry-level pocket cruiser. It typically trades at a modest value, representing a very low financial barrier to entry. Because it is small and easily trailerable, owners can bypass the significant recurring expenses of marina slip fees, winter hauling, and professional storage by keeping the boat on a trailer in a driveway or yard 4.
Refitting a Hullmaster 22 is highly cost-effective compared to larger cruising yachts. A new mainsail or jib represents a fraction of the cost of larger sails, and the simplicity of its systems makes the boat an excellent platform for do-it-yourself owners.
However, buyers must closely evaluate the condition of the trailer. A tandem- or single-axle trailer that has suffered from rusted frames, seized brakes, or dry-rotted tires can easily cost more to rehabilitate than the actual market value of the sailboat it carries. The model remains highly sought after and relatively common in the Great Lakes region and eastern Canada, but it is quite scarce in other coastal markets.
The Verdict 2
The Hullmaster 22 is an exceptionally tough, well-designed pocket cruiser that offers a rare combination of trailerable ease and true windward performance, thanks to its deep centerboard configuration. While it is too tender and light for serious offshore work, it represents a nearly perfect starter boat for coastal exploring, gunkholing, and lake sailing.
