Unsurpassed for 160 Years We operate a fleet of more than 60 tugboats, crew boats, and barges in 13 locations along the U.S. East Coast from Eastport, ME to San Juan, PR. The fleet includes 38 Z-Drive/tractor tugs and 20-plus vessels involved in coastal towing with more than a combined 270,000 H.P. In each port, McAllister is engaged in ship docking (servicing more than 1,000 steamship companies), general harbor towing, coastal towing, windfarm support, and bulk transportation. We are currently building two new tractor tugs at Washburn & Doughty, which will add more than 13,000 hp to our fleet. These assets and our talented teams will ensure that we continue the McAllister family tradition of being an innovative force in marine transportation.
