1973 First Parasail Winchboat Design Drawing 1973, McCulloh, designed the first self-contained parasail towing vessel called the "Winchboat". The Concept was inspired in part by the safety issues of the stationary platform, and the complex operation of the motorized platform. The mission was to combine the motorized parasail platform and tow vessel together to launch and recover the parasail canopy (via an inflation system) and parasailor (via a hydraulic winch) from the boats aft deck. The goal was to overcome the accidents with the platforms, with increased safety and efficiently of the operation using only two crew members. previous next
