Abstract

The Newfoundland and Labrador inshore fishing fleet is in a unique situation in that they fish up to 350 miles offshore. The industry evolved from a fleet fishing for cod in short trips close to home, until the collapse of that species in 1992, to a fleet fishing multiple species wherever they can. Unfortunately, the small fishing boat regulation did not evolve with the vessels. This gave rise, because of a number of factors, to vessels becoming wider and higher but not longer. In an effort to design a vessel more appropriate for the conditions and species being harvested an unrestricted vessel was designed for the fleet under a separate project (Friis, et al. 2007). -- This thesis describes the results of experiments conducted on this unrestricted vessel. The thesis looks specifically at four different bulbous bow options and how they compare to a conventional bow. Resistance, self-propulsion and head seas resistance, pitch and heave motion experiments were completed for the thesis. The intent is to contribute to the general knowledge of bulbous bow design for fishing vessels in Newfoundland and Labrador.
