bow - Front of a vessel cleat - Metal fitting on which a rope can be fastened gunwale - Upper edge of vessel's side hull - Body of a vessel port - Left side of a vessel propeller - Rotates and powers a boat forward or backward starboard - Right side of a vessel stern - Rear of a vessel beam - Maximum width of a vessel draft - Depth of water needed to float a vessel freeboard - Distance from water to lowest point of the boat where water could come on board keel - Main centerline (backbone) of a vessel or the extension of hull that increases stability in the water displacement and planning - two basic types of boat hulls are... displacement - Boats with ____________________ hulls move through the water by pushing the water aside and are designed to cut through the water with very little propulsion. slower speeds - Boats with displacement hulls are limited to round-bottomed hull - A ___________________________________ shape acts as a displacement hull. Most large cruisers and most sailboats have displacement hulls, allowing them to travel more smoothly through the water. planing hulls - Boats with ________________________ are designed to rise up and glide on top of the water when enough power is supplied true - T or F: boats may operate like displacement hulls when at rest or at slow speeds but climb toward the surface of the water as they move faster high speed - Boats with planing hulls can skim along at _____________________, riding almost on top of the water rather than pushing it aside Flat-Bottomed and Vee-Bottomed Hull - ____________________ and _____________________ shapes act as planing hulls personal watercraft (PWC) - 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 Displacement Mode - A planing hull, when operated at very slow speeds, will cut through the water like a displacement hull. plowing mode - As speed increases, a planing hull will have a raised bow, reducing the operator's vision and throwing a very large wake. Avoid maintaining a speed that puts your boat in __________________ planning mode - Your boat is in ___________________________ when enough power is applied so that the hull glides on top of the water. Different boats reach ______________________ at different speeds. Flat-Bottomed Hull - Advantage: Has a shallow draft, which is good for fishing in small lakes and rivers. Disadvantage: Rides roughly in choppy waters Deep-Vee Hull - Advantage: Gives a smoother ride than a flat-bottomed hull in rough water. Disadvantage: Takes more power to move at the same speed as flat-bottomed hulls. May roll or bank in sharp turns. Round-Bottomed Hull - Advantage: Moves easily through the water even at slow speeds. Disadvantage: Has a tendency to roll unless it has a deep keel or stabilizers. Multi-Hull - Advantage: Has greater stability because of its wide beam. Disadvantage: Needs a large area when turning. Length overall - dictates the equipment the vessel must have to comply with federal and state laws; is measured from the tip of the bow in a straight line to the stern of the vessel. NO - are bowsprits; rudders; outboard motors and motor brackets; handles; and other fittings, attachments, and extensions included in the measurement rudder - Steering device, usually a vertical blade attached to a post at, or near, the stern of the boat
