Design and Construction
The hull is solid fibreglass, consistent with the heavy hand-laid GRP practice the Snapdragon range used through the 1960s and 1970s, and the deck is likewise solid fibreglass. The bilge keel is a twin-keel arrangement that allows the boat to be beached, giving the 890 a practical advantage in tidal estuaries and shallow harbours where a fin-keel boat would ground hard. With a loaded draft ranging from 3.25 to 3.55 feet depending on load, the boat can enter even shallow marinas, and the 40% ballast ratio — iron ballast of 3,000 pounds against a 7,500-pound displacement — is a comparatively high figure that anchors the modest 9.5-foot beam. The displacement-length ratio of 242 and length-to-beam ratio of 3.05 place her firmly in the traditional narrow, heavy cruiser camp rather than the light-displacement racer lineage.
Rig and Handling
The 890 is built with a masthead sloop rig carrying 376 square feet of sail area, yielding a sail-area-to-displacement ratio of 15.70 — a modest figure that signals a boat tuned for steady cruising rather than sparkling upwind performance. The theoretical maximal speed of a displacement boat of this length is 6.6 knots, and under the optional inboard BMC diesel at 32 hp the calculated max speed is about 7.5 knots, a useful margin for motor-sailing against a tide. The capsize screening value of 1.94 and Motion Comfort Ratio of 22.5 are both in the stable, forgiving range for a coastal vessel of this size. Sheet sizing from the period specification is uniform at 10 mm (3/8 inch) diameter across jib, genoa, mainsheet, and spinnaker, with the mainsheet running long at 22.1 metres (72.5 feet) and the headsail sheets at 8.8 metres (29 feet) — practical numbers for an owner re-rigging or replacing running gear.
Accommodations
The available record offers no descriptive interior facts for the 890 beyond the hull and systems envelope, so the accommodations must be framed only by what is established: a 29-foot loa with 24-foot waterline, 7,500-pound displacement, and 19.21-gallon diesel capacity feeding the BMC engine. The wetted surface of about 226 square feet and immersion rate of 796 pounds per inch describe a hull that settles predictably under stowage and crew, but the sources do not document berth count, cabin layout, or head placement, and those must not be supplied from assumption.
Known Issues
No documented defect, flooding path, or structural weakness for the 890 appears in the available record. The 890's solid fibreglass deck is a documented construction fact. Owners and surveyors have left no quantified issue to carry forward as a con.
Refits and Ownership
Ownership of the production rights passed through Thames Marine's 1981 shutdown, a brief Maplin Marine distribution window, and ultimately to Boating Scene, which acquired the Snapdragon 890 range — a lineage that means spares and nomenclature can confuse a first-time buyer who meets the boat badged alternately as 890 or 29. The 32 hp BMC diesel remains the documented power plant, and the 7.5-knot calculated engine max gives a realistic baseline for auxiliary performance after repowering decisions.
The Verdict
The Snapdragon 890 is a deliberately traditional coastal cruiser: solid fibreglass hull and deck, a beaching-friendly bilge keel, and a high 40% ballast ratio that favours stability over speed. The masthead rig and 15.70 SA/D mark her as a steady sailer rather than a racer, and the documented production lineage explains why the same boat surfaces under two model names.
Pros
- Bilge keel allows beaching and shallow-marina access with 3.25–3.55 ft loaded draft.
- Solid fibreglass deck.
- High 40% ballast ratio and 1.94 capsize screening value indicate stable handling.
- Clear engine specification: BMC diesel at 32 hp, 7.5-knot calculated max speed.
Cons
- Sail-area/displacement of 15.70 is low for lively performance in light air.
- No documented interior layout or berth detail in the source record.
- Dual model naming (890 / 29) can obscure production-rights history for buyers.
