Sailing Performance & Handling
The sailing characteristics of the Colvic Watson 23 are dictated by its lifeboat heritage and its role as a motor sailer. With a high displacement-to-length ratio and a relatively modest sail plan, typically rigged as a masthead sloop or occasionally a ketch, the vessel is not intended to win regattas. Instead, it offers exceptional sea-kindliness. According to design insights from G.L. Watson & Co., the hull lines are heavily influenced by the firm's experience with seaworthy commercial craft, resulting in a boat that tracks exceptionally well and resists slamming in a head sea.
In practice, the Watson 23 is often used under "motor-sailing" conditions, where the sails act as stabilizers to dampen the rolling motion while the diesel engine provides the primary propulsion. Under sail alone, the boat requires a stiff breeze to get moving, and its pointing ability is limited by the drag of its substantial long keel. However, in a blow, it remains incredibly stable and predictable. The helm is typically heavy but communicative, and the high bulwarks and deep cockpit provide a sense of security that is rare in vessels under 25 feet. Owners frequently report that the boat feels significantly larger than its dimensions suggest, handling heavy weather with the composure of a 30-foot cruiser.
Interior Comfort & Variations
For a 23-foot vessel, the interior volume of the Colvic Watson 23 is remarkably generous, facilitated by its wide beam and high freeboard. The layout is dominated by the enclosed or semi-enclosed wheelhouse, which allows the skipper to navigate and steer protected from the elements—a defining feature that separates it from standard "pointy-end" sailing yachts. Below decks, the accommodation usually features a compact galley, a small dinette that can often convert into a berth, and a V-berth in the forepeak.
It is important for prospective buyers to recognize that while Colvic Craft molded the hulls to a high standard, many Watson 23s were sold as kits for home completion. This has led to a vast disparity in interior quality and layout. While some professional yard-finished examples feature high-quality teak joinery and clever storage solutions, others may have amateur finishes that require modernization. The hull itself remained consistent throughout the production run, but sibling models like the Colvic Watson 25.6, the 28, and the larger 31.5 and 34-foot variants followed the same design language, offering progressively more living space while maintaining the iconic canoe stern and rugged profile.
Known Issues & Buyer’s Checklist
When inspecting a Colvic Watson 23, the primary focus should be on the quality of the original fit-out and the age of the mechanical systems.
- Osmosis: Like many thick GRP hulls from the 1970s and 80s, Colvic hulls can be prone to osmotic blistering. While rarely structural due to the sheer thickness of the laminate, it is a common point for price negotiation and should be checked by a surveyor.
- Engine Maintenance: Because the Watson 23 relies heavily on its engine, the condition of the powerplant (often a BMC, Thorneycroft, or Perkins) is critical. Check for cooling system scale and exhaust elbow corrosion, which are common in older marine diesels.
- Window and Portal Seals: The large windows in the wheelhouse are a signature feature but are prone to leaking over decades of service. Evidence of water ingress around the internal woodwork is a high-signal indicator that the seals or frames require replacement.
- Deck Core: While the hulls are solid GRP, some decks were constructed with a balsa or plywood core for stiffness. Soft spots in the side decks or around the mast step can indicate core rot, a labor-intensive repair.
Community & Resources
The longevity of the design is supported by a dedicated community of enthusiasts. The Colvic Watson Owners Association remains the definitive resource for technical drawings, historical data, and advice on refitting these vessels. They maintain a repository of information regarding the various permutations of the Watson range, which is invaluable for identifying whether a specific boat was yard-finished or a home-build project.
The Verdict
The Colvic Watson 23 is a rugged, honest motor sailer that prioritizes safety and shelter above all else. It is an ideal vessel for those who wish to extend their sailing season into the shoulder months or for sailors transitioning from more athletic boats to a more comfortable, upright cruising style.
Pros:
- Extremely seaworthy lifeboat-derived hull design.
- Protected wheelhouse offers excellent weather protection.
- Surprising interior volume for a vessel of this length.
- Heavy-duty GRP construction provides long-term durability.
Cons:
- Limited sailing performance, particularly in light winds or when pointing upwind.
- Significant variation in interior quality due to kit-build options.
- The heavy displacement makes it slower under power than modern planing motorboats.
