Tennessees Serodino, Inc. recently built one of their popular Tiger class push boats for their own use. The M/V Charger, like others in the class, is 51.5 by 22.5 ft with a 5.5 ft draft. The hull is constructed of 3/8-inch plate with 1/2-inch plate over the propellers and bilge knuckles. Designed in house, the boat is a sister to a number that the company has built over the years. A pair of updated Tier 2 compliant QSK19-M main engines each powers this most recent version of the vessel. The engines each deliver 600 hp into Twin Disc MGX-5222-DC gears with 4.03:1 reduction.
