Lightweight and strong, fibreglass was found to be an excellent boat construction material and in 1946 California boat builder Bill Tritt was commissioned to build a 20-foot, high-performance fibreglass sailboat. It was so successful he made four of them. In 1949 hot rod, enthusiast Ken Brooks commissioned his friend Tritt to build a fibreglass body for a modified car he had constructed using a Jeep chassis. The resulting 1951 Brooks Boxer was exhibited at the Los Angeles Motorama show and generated favourable features in several magazines. This convinced Tritt to add car bodies to his boat-building business. In 1950, Tritt and some partners formed the Glasspar Company based in larger Santa Ana quarters. Using the Boxer pattern, he produced the first Glasspar G2 sports roadster.
