I am from Nova Scotia, and on of the big things i hate is the fishing gear. The fisherman have alot of surface gear and rope that floats on the surface or just below the surface of the water. Its not like some of the gear i have seen in the states were the extra line just sinks. So for the protection of your prop, i would have to say keep a close watch around the shore and when around fishing gear! I hope this is of some help!
