Dravo SteelShip Delivers Pilot Boats For Panama Canal Pilot boat Darter is one of nine 48-foot vessels of this type designed and built by Dravo SteelShip for Panama Canal Commission. Dravo SteelShip Corporation has an- nounced the recent completion and delivery of nine 48-foot pilot boats for the Panama Canal Commission. The single-screw pilot launches have all been delivered to the Canal Zone under their own power. They were de- livered two at a time for safety measures. The 2,200-mile trip typically took approxi- mately 15 days, with stops en route in New Orleans, Cozumel Island, and finally arrival in Panama at Colon. The vessels are powered by single GM Detroit Diesel 8V-71 engines rated 230 bhp at 1,800 rpm, and have proven themselves to be extremely seaworthy in their maiden voyage to the Canal Zone. Only the delivery crews have proven to be more rugged, as some of the boats have no sleeping, galley or other living accommodations onboard. Dravo SteelShip builds a wide variety of inland and offshore vessels in both steel and aluminum.
