Design and Construction
Both hull and deck are fiberglass, built by the British yard Thames Marine Ltd. as a solid-laminate boat rather than a cored structure in the hull itself. The in-house design team gave her a length-to-beam ratio of 3.00 with an 8-foot beam, and a displacement of 3,850 pounds carrying 1,550 pounds of iron ballast — a 40 percent ballast-displacement relationship that places her firmly in the small cruiser weight class. Her wetted surface runs about 172 square feet, and her immersion rate of roughly 560 pounds per inch means she sits heavily for her length, consistent with a moderate-racer DL-ratio of 212.
Keel Options and Draft
One of the 24's defining traits is that she was built with different keel alternatives, letting owners choose between a fin keel and a bilge keel built with different keel alternatives. The fin-keel version draws about 3.6 to 3.9 feet depending on load, while the bilge-keel model sits at roughly 2.5 to 2.8 feet — shallow enough to dry out against a quay or enter modest marinas. That flexibility is unusual in a boat this size and explains much of her appeal as a trailable or estuary-friendly cruiser.
Rig and Sail Handling
The Snapdragon 24 carries a masthead sloop rig with a sail area of 247 square feet. Her running rigging is uniformly 10 mm (3/8 inch) line, with jib and genoa sheets of 7.3 m, a mainsheet of 18.4 m, and spinnaker sheets of 16.2 m. The modest sheet lengths and single-spreader-scale rig keep her manageable shorthanded, and the masthead layout gives a large genoa option for light-air drive without overpowering the hull.
Engine and Performance
Several engine alternatives were fitted over the production run, including the Yanmar 1GM10 and the Nanni 260HE, each driving through a shaft drive. With the Yanmar the calculated top speed is about 5.1 knots; the Nanni raises that to roughly 6.6 knots, against a theoretical displacement-hull maximum of 6.0 knots for her length. Her capsize screening value is 2.05, which indicates that this boat would not be accepted to participate in ocean races. Her Motion Comfort Ratio of 16.9 to 17.3 places her among the firmer-riding small bilge and fin-keel cruisers rather than featherweight daysailers.
Accommodations
Below, the Snapdragon 24 is equipped with one cabin, five berths, a galley, and a toilet facility — a full weekend layout in a 24-foot hull. The interior is finished in teak, giving her a period warmth that survives in many examples. The five-berth count is ambitious for the length but speaks to her role as a family pocket-cruiser rather than a racer with stripped accommodation.
The Verdict
The Snapdragon 24 is a sensible small British cruiser whose twin keel options, solid glass hull, and genuine five-berth interior make her a practical entry to trailer- or marina-based sailing. She is not an offshore racer by the numbers, but as a sheltered-water and estuary boat she remains a well-considered design.
Pros
- Choice of fin or bilge keel for draft flexibility
- Solid fiberglass hull and deck construction
- Five berths with galley and head in 24 feet
- Multiple engine options with shaft drive
Cons
- Capsize screening value excludes ocean racing
- Heavy immersion rate for her length
- Modest theoretical top speed under power
