The Bonito 22 is a quintessential Southern Hemisphere trailer sailer, primarily manufactured in New Zealand during the 1970s and 1980s. Designed to meet the growing demand for a vessel that could be easily towed behind a family car while providing genuine overnight capabilities, the Bonito 22 became a staple of the "TS" (Trailer Sailer) racing and cruising circuits. Its design philosophy emphasizes a balance between a relatively lightweight hull for transport and a hull shape that remains stable in the choppy coastal waters of the Hauraki Gulf or the Australian seaboard.

While primarily recognized as a single-model run, the Bonito 22 shares design DNA with larger and smaller vessels in the Bonito range, such as the Bonito 5m powerboats and the larger cruising yachts produced by the same builders. The 22-foot variant is most notable for its "pop-top" cabin roof, a feature that significantly increased its utility without the aerodynamic drag of a high fixed coachroof during transit.
Sailing Performance & Handling
The Bonito 22 is characterized by a high-aspect-ratio rig and a versatile lifting keel system, which dictates its handling profile. On the water, the boat is known for being relatively stiff for a trailer sailer, thanks to its internal ballast and the weight concentrated in the swing keel. When the keel is fully deployed, the boat tracks well upwind, though like many light-displacement vessels of its era, it can be prone to leeway in heavy gusts if the sails are not properly trimmed.
Anecdotal reports from regional trailer sailer associations suggest that the Bonito 22 is particularly adept at off-the-wind sailing. Its flat aft sections allow it to plane in favorable conditions, a trait it shares with more modern sports boats. The rudder is typically transom-hung, providing a direct and communicative feel to the helm, though it requires significant effort to hold when the boat is over-canvassed. Its Displacement to Length ratio is moderate, ensuring it does not "hobby-horse" excessively in a short chop, making it a more comfortable sea boat than many of its 18-to-20-foot contemporaries.
Interior Comfort & Variations
For a 22-foot vessel, the Bonito 22 offers a surprisingly functional interior, largely due to the inclusion of a pop-top. This mechanism allows for standing headroom in the main cabin area when at anchor, a luxury rarely found in trailerable boats of this length. The layout is traditional, featuring a V-berth forward, a small chemical or marine head tucked beneath the cushions, and twin settee berths in the saloon.
The cabinetry is typically finished in a mix of molded fiberglass liners and teak trim, reflecting the era's preference for low-maintenance surfaces. The galley is rudimentary, usually consisting of a single-burner stove and a small sink, but it is sufficient for weekend coastal hops. Variations of the interior primarily involve the keel housing; some models feature a more intrusive centerboard case, while later "Mk II" versions or custom fits by owners may include improved storage lockers and upgraded electrical panels. The boat's 8-foot beam (approximate) provides enough internal volume to accommodate a family of four for short durations, though it is most comfortable for a couple.
Known Issues & Buyer’s Checklist
Prospective buyers should focus on the mechanical integrity of the lifting keel and the structural condition of the pop-top mechanism.
- Keel Pivot and Cable: The most critical inspection point is the swing keel pivot pin and the lifting cable. Corrosion in the keel trunk or a frayed stainless steel cable can lead to catastrophic failure. It is common for the pivot hole in the cast-iron keel to become "ovalized" over decades of use, leading to an audible "clunking" sound while under sail.
- Pop-Top Seals and Hardware: The seals around the pop-top often perish, leading to water ingress during heavy rain. Additionally, the gas struts or manual supports that hold the roof up should be checked for corrosion and reliable operation.
- Deck Compression: Like many boats with a deck-stepped mast, the Bonito 22 can suffer from compression issues at the mast step. Inspect the area for hairline fractures or "dishing" where the mast meets the cabin top.
- Transom Stress: If the boat has been used with a heavy four-stroke outboard engine on a bracket, the transom should be checked for stress cracks or delamination.
Community & Resources
The Bonito 22 enjoys continued support through regional trailer sailer clubs, particularly in New Zealand. The New Zealand Trailer Yacht Association (NZTYA) maintains records of the model's handicap ratings and often features the boat in its class racing divisions. While there is no longer an active manufacturer website, the technical community often congregates in regional "Trailer Sailer" Facebook groups and forum-based communities where owners share DIY mast-raising systems and keel refurbishment guides.
The Verdict
The Bonito 22 remains a highly regarded entry-level cruiser for those who prioritize portability without sacrificing the ability to spend a night on the water in relative comfort.
Pros:
- Versatile Draft: The lifting keel allows for beaching and access to shallow anchorages.
- Headroom: The pop-top feature provides standing room that is exceptional for this size class.
- Towing Ease: At 22 feet, it is at the upper limit of easy towing, making it a true "anywhere" coastal cruiser.
Cons:
- Maintenance Intensive: The moving parts of the keel and pop-top require more upkeep than a fixed-keel yacht.
- Age: Most hulls are over 40 years old, requiring careful inspection of the fiberglass and rigging.
- Cockpit Space: The cockpit can feel cramped when sailing with more than three adults due to the mainsheet positioning.
