Snapdragon 670 Information, Review, Specs

The creation of the Snapdragon 670 in 1963 marked an important point in Thames Marine's history, a company that began as Thames Structural Plastics in 1959, specializing in fiberglass components before pivoting to boat building. The builder's ethos, as evident in the Snapdragon 670, centered on producing practical, sturdy, and family-friendly cruising yachts that were accessible and comfortable. Leveraging their expertise in fiberglass construction, Thames Marine aimed to create vessels well-suited for the often-shallow waters around the UK.

Designed by David Feltham, the Snapdragon 670 was a response to the demand for reliable small cruisers. A key design philosophy behind the Snapdragon range, and prominently featured in the 670, was the incorporation of twin (bilge) keels. This design choice provided excellent shallow-draft capabilities, allowing the yacht to sit upright on drying moorings or in tidal areas. While the twin keel was standard, a deeper standard keel model was also available, offering owners a choice depending on their cruising grounds and preferences. The enduring popularity of the design is also evidenced by the fact that the Snapdragon 670 design was licensed to another company and sold as the Mirage 22.

Sailing Performance and Handling

The Snapdragon 670 is characterized as a moderate-weight sailboat that delivers reasonably good performance for its size. Owners and reviewers often describe it as a very stable and stiff boat, capable of standing up to a decent breeze. This inherent stability contributes to a comfortable motion in a seaway, a desirable trait for a cruising vessel. The twin keel configuration, while enhancing shallow-water access and the ability to take the ground, influences its handling. Anecdotal evidence suggests that the boat is forgiving and predictable, making it a suitable choice for both seasoned sailors and those new to yachting. Its robust nature makes it well-adapted for coastal cruising, providing a secure platform for exploring varied conditions. It is noted that while stable, the boat has a low righting capability if capsized.

Accommodations and Layout

Despite its modest length overall of 22 feet, the Snapdragon 670 was designed to maximize interior volume for comfortable cruising. The interior typically features a functional layout, providing essential amenities for overnight stays and extended weekends. While specific headroom varies, some owners of average height have reported standing headroom, which is a notable feature for a boat of this size. The cabin interior would typically include a V-berth forward, a compact galley area, and a saloon space that often converts into additional sleeping berths. Storage solutions would have been integrated throughout the cabin, utilizing available spaces effectively. The general finish quality, characteristic of Thames Marine, focused on durability and practicality, often featuring robust fiberglass moldings complemented by simple, functional joinery, offering a warm and inviting atmosphere suitable for a family cruiser.

Owner's Perspectives

Owners of the Snapdragon 670 consistently praise its solid construction and its ability to handle varied conditions with a reassuring stability. The twin keel arrangement is frequently highlighted as a significant advantage, providing unparalleled access to shallow waters and the convenience of drying out in tidal harbors. The enduring appeal of the Snapdragon 670 is evident in the active community of owners, with forums and associations dedicated to these classic British yachts. These platforms serve as valuable resources for sharing knowledge, discussing maintenance, and connecting enthusiasts who appreciate the boat's robust build and its suitability as an affordable and reliable cruiser. Many owners undertake restorations, a testament to the lasting character and structural integrity of these vessels. While specific common weaknesses are not broadly documented beyond general wear and tear expected of a boat of its age, the community support ensures that solutions and advice are readily available for any encountered issues.
