Design and Construction
Thames Marine Ltd. built both the hull and deck in fiberglass, with a solid-laminate hull rather than a cored structure. The in-house design team gave the Snapdragon 24 an 8-foot beam and a length-to-beam ratio of 3.00.
She displaces 3,850 pounds and carries 1,550 pounds of iron ballast. That 40 percent ballast-displacement relationship puts her firmly in the small-cruiser weight class. Wetted surface is about 172 square feet, while an immersion rate of roughly 560 pounds per inch means she sits heavily for her length. This is consistent with her moderate-racer DL-ratio of 212.
Keel Options and Draft
One of the Snapdragon 24’s defining features is her choice of fin or bilge keel. Depending on load, the fin-keel version draws about 3.6 to 3.9 feet. The bilge-keel model draws 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 of 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 247 square feet of sail area. Her running rigging uses 10 mm (3/8 inch) line throughout. The jib and genoa sheets are 7.3 m long, the mainsheet is 18.4 m, and the spinnaker sheets are 16.2 m.
The modest sheet lengths and single-spreader-scale rig help keep her manageable when sailing shorthanded. The masthead layout also allows for a large genoa to provide drive in light air without overpowering the hull.
Engine and Performance
Several engines were fitted during the production run, including the Yanmar 1GM10 and Nanni 260HE, both with shaft drive. With the Yanmar, calculated top speed is about 5.1 knots. The Nanni raises that figure to roughly 6.6 knots, compared with a theoretical displacement-hull maximum of 6.0 knots for her length.
Her capsize screening value is 2.05, indicating that she wouldn’t be accepted for participation in ocean races. A Motion Comfort Ratio of 16.9 to 17.3 places her among the firmer-riding small fin- and bilge-keel cruisers rather than among featherweight daysailers.
Accommodations
Below deck, the Snapdragon 24 has one cabin, five berths, a galley, and a toilet facility—a full weekend layout within a 24-foot hull. The teak interior brings period warmth and survives in many examples.
Five berths is an ambitious count for a boat of this length, but it reflects the Snapdragon’s intended role as a family pocket cruiser rather than a racer with stripped-out accommodations.
Verdict
The Snapdragon 24 is a sensible small British cruiser. Her fin- and bilge-keel options, solid fiberglass construction, and genuine five-berth interior make her a practical entry into trailer- or marina-based sailing. She isn’t an offshore racer by the numbers, but she remains a well-considered design for sheltered waters and estuary cruising.
Pros
- Choice of fin or bilge keel for draft flexibility
- Solid fiberglass hull and deck construction
- Five berths, a galley, and a toilet facility in 24 feet
- Multiple shaft-drive engine options
Cons
- Capsize screening value excludes her from ocean racing
- Heavy immersion rate for her length
- Modest theoretical top speed under power
