Colvic Watson 31.5 Buyer's Guide
Shopping for a used Colvic Watson 31.5 means looking at a 1978-era motor-sailer from the Colvic Craft and G. L. Watson collaboration, a heavy boat with a 31 foot 6 inch hull and a canoe stern. She was also sold as the Navrik 32, so used Colvic Watson 31.5s under either name describe the same design. Because Colvic sold these as hulls and decks in varying states of completion, no two boats are finished alike, and the hulls themselves were very sound even where the build quality varied greatly.
Layouts on the Used Market
The Watson 31.5 came with a variety of cabin plans, but the standard count of four to five berths is the common denominator across the class. Individual layouts reflect whether a professional yard or an amateur completed the boat, so a buyer should treat the accommodation plan as boat-specific rather than model-standard. The full, high bows and canoe stern give her a traditional motor-sailer profile, and the 11-foot beam provides the width that the interior plans were drawn around.
Equipment and Common Upgrades
On the brokerage market these boats commonly carry a chartplotter, heating, solar, inverter, bow thruster, and autopilot as fitted equipment. For a buyer, that cluster means modern navigation and energy independence are usually already addressed, while a bow thruster and autopilot take the sting out of handling a heavy hull in marinas. The original design paired a big engine with a small rig, so the electrical and steering upgrades seen on most examples lean toward motor-sailer use rather than performance sailing.
What to Inspect
The defining used-market risk is that quality varied greatly between boats, even though the hull laminate was sound. Inspect the finished joinery, systems routing, and deck hardware mounting because the semi-kit provenance means one example may be professionally executed and another roughly finished. The variable completion standard is the one issue a survey must address boat by boat.
Availability and Buyer's Takeaway
These boats are typically found in the United Kingdom, Netherlands, Greece, and Germany. A buyer's short checklist: confirm which rig is fitted (sloop, ketch, or rare gaffer), verify the berth count and layout against the specific boat, check that the common upgrades (heating, solar, inverter, autopilot, bow thruster, chartplotter) are present and working, and have a surveyor assess finish quality closely because the class is known for wide variation in execution.
