Founded by Ray Walsh and Len Wakefield as Thames Structural Plastics, originally to build fiberglass components for a number of industries. The emphasis turned to the manufacture of boats early on. The first sailing yacht was the 23' SNAPDRAGON (1962). Expansion came in a number of stages and the company started to build it's own factory at Canvey Island, Essex. (1965)
As TSP Ltd., the company began doing the moldings for other boat builders; Thames Marine became the name for selling their own models.
There was also a branch that built power boats and another to build the Prout line of catamarans.
No longer in business.

Years in Business: 1959 - 1981
