Boats with displacement hulls... - ANSWER-Move through the water by pushing the water aside and are designed to cut through the water with very little propulsion. Have slower speeds. Most large cruisers and sailboats.Boats with planing hulls - ANSWER-Are designed to rise up and glide on top of the water when enough power is supplied. Glide across the water at high speeds. Flat bottomed or vee bottomed. Most small power-driven vessels, including personal watercraft (PWCs) Personal watercraft - ANSWER-Jet Ski. A small vessel that uses an inboard jet drive as its primary source of propulsion, and is designed to be operated by a person or persons sitting, standing, or kneeling on the vessel rather than inside the vessel Different Modes of Planing Hulls - ANSWER-Displacement Mode:Very slow speed. Cuts through the water like displacement hulls Plowing Mode: As speed increases, bow rises, reducing operators vision, throwing large wake, Avoid maintaining this mode.
Planing Mode:Hull glides across the water. Very high speed.
Flat Bottom Hull - ANSWER-Shallow draft, good for fishing in lakes or rivers one bad thing is it rides roughly in choppy waters Deep Vee Hull - ANSWER-Gives a smoother ride than flat bottom hull in rough water one disadvantage is takes more power to move at same speed as flat bottom. May roll or bank in sharp turns Round Bottom Hull - ANSWER-Moves easily through water at slow speeds. Bad thing: has a tendency to roll unless it has a deep keel or stabilizers Multi-Hull - ANSWER-Has greater stability because of its wide beam. Disadvantage: Needs a large area while turning
