John Murgas, owner of Petersburg Marine, tests the new ramp with a demonstration of his self propelled hydraulic trailer. Manufactured by Hostar, Murgas helped design the trailer for the type of vessels he handles. A diesel engine drives a hydraulic pump and, through hydraulic lines, reaches each of the wheels' hydraulic motor. Murgas and his crew are always arguing over who gets to drive it. "We try to take turns, but everyone cheats," said Murgas.
