Design Brief & Intent
Robert Tucker designed the Corribee to be an affordable, highly capable pocket cruiser that could handle offshore conditions while remaining easy to manage for a novice skipper. While the original 1964 Mk I was built of wooden clinker 1, the Mk II transitioned fully to glass-reinforced plastic (GRP) and featured a redesigned, stepped deck molding that created a distinct two-level coachroof. This design change significantly increased interior volume and improved cabin headroom to 4 feet, 8 inches, giving the boat the feel of a miniature yacht rather than a cramped day-boat.
The interior layout is a masterclass in space-efficiency. Despite a narrow 7-foot, 2-inch beam, the builders managed to squeeze in four berths: a double V-berth in the forepeak and two single quarter berths extending aft into the saloon. Accommodation is basic but functional, containing a slide-out galley tray, a compact chart table, and space for a chemical toilet beneath the forward berth. The joinery is simple, relying on modest teak or mahogany trim over a functional GRP inner liner. The Mk II was built to compete directly with contemporary British pocket cruisers like the Leisure 20 and the Hurley 22, standing out for its superior aesthetic lines and more traditional, sea-kindly handling.
Variations & Configurations
The Corribee Mk II was offered with two primary underwater profiles: a single fin keel drawing 3 feet, or a twin-keel (bilge keel) configuration drawing just 2 feet, 2 inches. The twin-keel version was immensely popular in the United Kingdom and northern Europe, allowing the boat to dry out upright on cheap, tidal mud moorings. To improve windward performance, which is traditionally a weak point for bilge-keeled boats, later Mk II models replaced the early symmetrical keels with asymmetrical aerofoil bilge keels that generate lift when heeled.
Rigging configurations also varied. While most Mk IIs were rigged as masthead sloops, Newbridge offered both a standard rig and a tall rig 3. The tall rig featured a taller spar that increased sail area, which was often paired with the fin-keeled hull to boost light-wind speed. Additionally, a small percentage of Corribees were fitted with junk rigs (Chinese lug rigs), mirroring the design of their sister ship, the Newbridge Coromandel. Veteran singlehanders, such as high-latitude voyager Roger Taylor, have famously favored these junk-rigged conversions for their unparalleled ease of reefing in heavy weather.
Sailing Performance & Handling
The sailing dynamics of the Corribee Mk II are highly predictable and reassuring. With a displacement of 2,000 pounds and a ballast-to-displacement ratio of 44.0%, she is exceptionally stiff. Carrying 880 pounds of cast iron ballast encapsulated deep within her GRP keels, the boat stands up to her canvas with authority, refusing to heel excessively even when caught in sudden gusts. Her displacement-to-length ratio of 208.08 indicates a moderate displacement hull that provides a comfortable, sea-kindly motion, cutting cleanly through chop without the violent slamming associated with modern, flat-bottomed sportboats.
Under sail, she is remarkably light on the helm and tracks straight, aided by her longish keel profile and a skeg-supported rudder 5. With a sail-area-to-displacement ratio of 15.72, the standard-rigged model can be somewhat sluggish in light airs, necessitating a large genoa or the tall-rig option to keep moving. However, when the wind rises, the boat truly comes into her own. Her motion comfort ratio of 12.73 and capsize screening ratio of 2.28 show that while she behaves like a lively pocket cruiser, her generous ballast ratio and robust hull lines make her incredibly forgiving in a blow.
Known Issues & Triage
Decades of service have highlighted specific structural vulnerabilities that prospective buyers should inspect. The most prominent issue involves the mast step. Unlike the Mk I, which utilized a traditional compression post, the Mk II relies on a laminated fiberglass deck beam across the cabin roof. Over-tensioning the standing rigging can flex this beam, dishing the mast step and rotting the marine plywood backing pads glassed beneath it. Triage requires cutting away the internal headlining, removing the rotted timber, and glassing in a reinforced hardwood or metal support.
The chainplates and surrounding deck are also prone to stress. Bulging around the shroud U-bolts indicates that the rigging has been over-tensioned, which can be corrected by installing larger, heavy-duty stainless steel backing plates beneath the side decks. At the bow, the original cast-aluminum bow roller often cracks under the upward load of the forestay. Veteran owners resolve this by installing a custom stainless steel assembly featuring a strap that extends down the stem of the hull to properly distribute the load.
Finally, the rudder and skeg require close inspection. On twin-keel models, the hardwood core inside the base of the skeg is prone to rot if water weeps past the pintle bolts. This requires drilling out the wet wood, epoxying in a new hardwood block (such as teak), and sealing the entire assembly with GRP.
Modernization & Upgrades
Modernizing a Corribee Mk II typically begins with propulsion. The original boats either featured ancient, temperamental outboards or heavy, unreliable inboard gasoline engines that dragged on sailing performance 10. The standard modern upgrade is to glass over any old sail-drive apertures and mount a modern 4-hp to 6-hp long-shaft, four-stroke outboard on a heavy-duty transom bracket.
Because small outboards provide minimal electrical charging, owners heavily focus on upgrading the electrical system. Installing a 50-watt to 100-watt solar panel on the companionway hatch garage, paired with dual lithium iron phosphate (LiFePO4) batteries, is now common practice. This setup easily powers modern necessities, including a DSC VHF radio, depth sounders, GPS, and a tiller-mounted autopilot. Other popular upgrades include replacing the original aluminum deck cleats with marine-grade 316 stainless steel, through-bolting new acrylic windows with butyl tape, and installing a modern mainsail stackpack with lazy jacks.
Market Snapshot & Economics
The Corribee Mk II enjoys a dedicated cult following, particularly in the United Kingdom, where hundreds were built. On the brokerage market, they represent an incredibly high level of seaworthiness for a very low entry cost. However, buyers must be realistic about refit economics. Because the market value of a 21-foot boat from this era is modest, embarking on major professional restorations—such as hull repaints, purchasing new sails, or replacing a rotted road trailer—can quickly exceed the market value of the vessel.
The most economically sensible approach is to purchase a well-maintained, "turn-key" example. Finding a boat that already comes with a galvanized, roadworthy trailer, a recently purchased four-stroke outboard, and a decent suite of sails represents a massive financial advantage over buying a cheap "project" boat.
The Verdict
The Corribee Mk II is an exceptional pocket cruiser that punches far above its weight class. It offers an unbeatable blend of classic aesthetics, forgiving handling, and a proven pedigree of ocean-crossing capability. While it lacks the interior volume and standing headroom of modern, high-sided production boats, it compensates with an incredibly solid feel in heavy weather. For budget-conscious pocket cruisers, singlehanders, or adventurous couples, the Corribee Mk II is a timeless masterpiece.
