Seattle City Light has awarded a contract to Kvichak Marine Industries to build a 25.8-ft push boat designed by Kvichak Marine to operate with the service barge at the Diablo Dam in the North Cascades.
The hull and superstructure will be constructed of marine grade aluminum alloy plate and extrusions. Two vertical push knees will be located at the bow. The knees will be padded by 6” D-section rubber. A 1,500 lb davit with manual winch will be mounted on the stern.
The push boat will be powered by twin John Deere 300 hp turbo charged diesel engines with stainless steel props in enclosed nozzles, allowing for speed of 8 knots while pushing the barge.
Delivery is scheduled for July 2010.
