The Snapdragon 670, introduced by Thames Marine in the late 1960s, represents a refined evolution of the builder's earlier 21 and 23foot models. Designed primarily as a compact family cruiser, this 22foot (6.7meter) yacht was engineered to provide maximum interior volume and stability within a footprint that remained manageable for a small crew. Its hull is characterized by a highvolume, robust profile that prioritizes safety and accommodation over pure aerodynamic speed. Most 670s were equipped with the builder's signature bilge keels, a design choice that cemented the model's popularity in the tidal estuaries of the United Kingdom, allowing the vessel to "take the ground" and remain upright on drying moorings.
