Re: what causes a boat to porpus. A boat porpoises when the bow is being forced up into the air. It will will reach a certain attidude and then the bow will fall back down causing the up and and down motion. As to why your specific boat is doing this I can't say. Maybe try shifting a bit more weight toward the bow.
Definition of porpoise. 1 : any of a family (Phocoenidae) of small gregarious toothed whales; especially : a blunt-snouted usually dark gray whale (Phocoena phocoena) of the North Atlantic and North Pacific that typically ranges from 5 to 6 feet (1.5 to 1.8 meters) in length.
