M/V Loop Responder from North American Shipbuilding Comandante Cianciulli fireboat from Trinity Marine OUTSTANDING OF T he year's portfolio of out- standing workboats includes a variety of vessels, each one distinctive in both design and function, from the Voith Schneider propelled 155-foot-long M/V Loop Responder, reportedly the most pow- erful tug boat in the world, to the 26.5-foot-long fireboat from Workboats Northwest. Overall the list is fairly balanced regarding ves- sel types, as three fireboats, three towboats and two oil skimmers made the top thirteen. The list is rounded out with a tug, crewboat, a patrol boat, a shrimper and a pilot boat.
