Design Brief & Intent
The Crabber 17 was conceived to bridge the gap between open sailing dinghies and the larger, cabin-focused Shrimper 19. Roger Dongray's brief was to create a boat light enough to be towed behind a standard family vehicle, easily launched and retrieved by a single person, yet substantial enough to provide a secure "sit-in" feel and overnight camping capabilities. She stands in contrast to other dayboats of her era, such as the Drascombe Lugger or Devon Yawl, which are more lightly ballasted and carry open, dinghy-like cockpits. The Crabber 17 features a solid, hand-laid GRP hull with encapsulated bilge ballast and an integral centerplate case, yielding a much higher level of initial stability.
Her interior is basic but highly functional, lined with warm iroko or teak trim. It is dominated by two V-berths that stretch beneath the foredeck, creating a cozy sleeping space for two adults. While there is no standing headroom or dedicated galley, the true genius of the design lies in its interaction with the cockpit. By raising the standard folding canvas pram-hood and attaching a cockpit tent backdrop, the open boat is instantly transformed into a dry, light, and surprisingly spacious shelter. For day sailing, the long cockpit easily accommodates up to five adults, who can sit comfortably on teak-slatted bench seats protected by high, secure coamings.
Variations & Hull Configurations
Over her long production run, the core hull shape of the Crabber 17 has remained virtually unchanged, testifying to the soundness of Dongray’s original lines. The most significant shift in the model's history occurred in 2015, when the builder rebranded the entire trailer-sailer range, officially re-designating the Crabber 17 as the Shrimper 17. Aside from cosmetic changes and updated deck hardware, the boats are structurally identical and share the same hand-laid fiberglass mold.
The rigging arrangement is a traditional high-peaked gaff sloop, utilizing a mainmast, boom, and gaff constructed from Sitka Spruce, paired with a pivoting wooden bowsprit. A critical feature of this configuration is the deck-stepped stainless steel tabernacle, which allows the mast to be lowered and raised. For auxiliary power, the design incorporates a clever internally mounted outboard well located aft of the cockpit, but forward of the transom-hung rudder. Sized to accommodate a 4 hp to 6 hp outboard, this well places the propeller deep in the water to prevent cavitation in a rolling seaway and ensures the prop wash flows directly onto the rudder for unparalleled low-speed maneuverability. While older two-stroke outboards could be easily lifted out and replaced with a fairing plate to reduce drag under sail, modern four-stroke outboards are heavier and more bulbous, usually remaining in the well throughout the sailing season.
Sailing Performance & Handling
On the water, the Crabber 17 behaves with a lively and responsive personality that reflects its light-to-moderate Displacement-to-Length ratio of 158.5. With a displacement of 1,450 pounds and a generous sail area of 178 square feet, she carries a Sail Area to Displacement ratio of 22.2. In physical terms, this high ratio ensures she is remarkably quick to accelerate in light airs, shaking off the sluggish, heavy feel common to many traditional-looking pocket cruisers. With her steel centerplate fully lowered to a draft of 4 feet, she grips the water effectively; when the plate is raised, her draft is reduced to just 1 foot 7 inches, allowing her to slip into thin-water creeks or be easily winched onto a trailer.
At the helm, the boat feels remarkably stable. The combination of 217 pounds of encapsulated bilge ballast and the heavy centerplate provides a reassuring righting moment, giving the boat a safe, stiff feel. However, because of her gaff rig, she does not point as high as modern Bermudan-rigged dayboats. On a windward beat, sailors must accept a wider tacking angle. Furthermore, weather helm increases significantly as the hull heels. To keep the tiller balanced and prevent the rudder from acting as a brake, it is vital to reef the mainsail early—typically when winds rise above 10 to 12 knots. In very light winds or chopped seas, her low momentum can sometimes cause her to miss stays during a tack, requiring the sailor to back the jib to bring her head through the wind. Her Capsize Screening Ratio of 2.17 reflects her Category C classification, indicating she is a highly capable day-sailer and coastal cruiser for estuaries and local coastlines, but is not designed for open-ocean passage-making.
Market Snapshot & Economics
The Crabber 17 occupies a premium niche on the secondary market. Unlike mass-produced fiberglass hulls from the same era that have depreciated significantly, this model commands a strong resale value, driven by her timeless aesthetic, robust construction, and the high prestige of the Cornish Crabbers brand.
This market standing was tested in early 2024 when the original builder, Cornish Crabbers LLP, entered voluntary liquidation due to significant outstanding debts. This caused temporary anxiety regarding the future of the brand and parts availability. However, the brand's long-term value was quickly recognized. By mid-2024, Poole-based Blue Lagoon Marine acquired the intellectual property, brand name, and molds, subsequently establishing a new entity, Cornish Crabbers Ltd. With production continuing in Cornwall, technical support, replacement spars, and the supply of brand-new vessels are fully secured. For secondary market buyers, this ensures excellent part availability and stabilizes residual values. From a towing perspective, the boat's all-up towing weight on a standard road trailer is approximately 2,200 pounds, making her highly economical to transport behind a standard family sedan or mid-sized SUV without the need for a dedicated, heavy-duty tow vehicle.
Known Issues, Triage & Upgrades
Owning a Crabber 17 requires a willingness to engage in regular wooden spar maintenance. The Sitka Spruce mast, boom, gaff, and bowsprit are vulnerable to rot if their protective coatings are neglected. Water can easily penetrate the wood fibers around screw holes, fittings, and the pivot joints of the tabernacle. Refitting neglected spars requires stripping them back to bare wood, treating any soft spots with epoxy, and applying eight to ten coats of a breathable woodstain or marine varnish.
The steel centerplate and its lifting gear are another critical maintenance area. The plate operates within a molded fiberglass trunk. Over time, the lifting wire, winch, and pivot pin can wear or corrode. If the pivot pin develops play, the centerplate can jam or slide out of alignment. Owners should periodically inspect these components when the boat is on its trailer, replacing the pivot bolt and lifting cables if any signs of wear or corrosion are found.
Additionally, the cockpit is self-draining, but because the forward cabin floor sits below the waterline, any severe heel that submerges the gunwales can lead to flooding in the cabin if the companionway is open. Keeping the cockpit drains completely clear of debris and ensuring the manual bilge pump is in perfect working order are mandatory safety practices. Vibration from heavy four-stroke outboards can also cause minor stress cracks in the gelcoat around the engine well, requiring structural reinforcement if flex is detected.
Modernization efforts among veteran owners frequently focus on simplifying the rig and enhancing comfort. A popular upgrade is the installation of a custom-designed tabernacle lowering system or helper gin poles, which allow a single-handed sailor to step and unstep the mast safely at the launch ramp. Upgrading the cockpit canvas with a high-quality, modern cockpit tent significantly extends the cruising season, turning the dayboat into a dry coastal camper. Furthermore, many owners are now replacing old, noisy petrol outboards with modern electric propulsion systems. Electric outboards are highly suited to the Crabber 17’s internal well, eliminating petrol fumes in the cockpit lockers and operating silently. These systems are typically paired with lightweight lithium iron phosphate batteries secured in the side lockers.
The Verdict
The Cornish Crabber 17 remains one of the most charismatic, practical, and enduring pocket cruisers ever designed. It strikes an exceptional balance between the romantic charm of a traditional gaff-rigged working boat and the low-maintenance practicality of fiberglass. While she demands more maintenance than a modern, stark daysailer and requires active sail management to avoid heavy weather helm, she rewards her owners with a stable, sea-kindly ride, a massive and highly convertible cockpit, and a community of passionate enthusiasts 4. For the coastal explorer or creek-crawler looking for a high-character trailer-sailer that holds its value, the Crabber 17 is nearly peerless.
