This report describes research conducted at MIT on bulbous bow retrofits applied to a Canadian trawler 50 meters in length. This is the third vessel in a series of three trawler hulls included in a larger study. The most significant part of this work is the ship model towing tank results. Experimental data and analyses are supplemented by results from the MIT 5-D Ship Motions Program and results from a resistance regression model implemented on computer. In general, results show significant reductions in shaft horsepower requirements with the simple bulb designs tested. Benefits are greater at higher speeds.
