Nj Boating License Exam new exam Bow front of a ship Cleat Metal fitting on which a rope can be fastened Gunwale the upper edge of the side of a boat Hull Body of a vessel Port Left side of a vessel Starboard right side of a vessel Stern Rear of a vessel Beam Maximum width of a vessel Freeboard Distance from water to lowest point of the boat where water could come on board Draft Depth of water needed to float a vessel Keel Main centerline (backbone) of a vessel or the extension of hull that increases stability in the water Displacement Hull The type of hull that plows through the water Planing Hull type of hull that is shaped to lift out of the water at high speeds and ride on the surface Vessels that have planing hulls most small vessels, PWC's, and small sailboats all have: Personal Watercraft 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 plowing mode. Planing Mode Your boat is in planing mode when enough power is applied so that the hull glides on top of the water. Different boats reach planing mode at different speeds. Length overall Total length of the ship from bow to stern Rudder Steering device, usually a vertical blade attached to a post at, or near, the stern of the boat Outboard Engine a portable, self-contained package of an engine, gear case, and propeller that is attached to the transom of a boat Transom Vertical surface at the back of the hull Tiller Lever used to turn a rudder to steer a boat Inboard Engines An inboard is a four-stroke automotive engine adapted for marine use. Inboard engines are mounted inside the hull's midsection or in front of the transom. Attached to propeller through bottom of hull Stern drives Stern drives are known also as inboard/outboards (I/Os) because they combine features found on both inboard and outboard engines. Stern-drive engines are four-stroke automotive engines adapted for marine use and are mounted inside the boat. Two-stroke engine An engine design that produces one power stroke for each revolution of the crankshaft. Four-stroke engine Also known as Otto cycle. A combustion cycle that consists of an intake, a compression, a power; and an exhaust stroke. Also called four-stroke engine. Jet drive propel a vessel by forcing a jet of water out the back of the vessel. Directing this jet of water steers the vessel Impeller Device used to pump and force water under pressure through a steering nozzle at the rear of the vessel Intake Opening in the hull that draws water toward the impeller Intake grate Screening cover over the intake, which prevents large debris from entering Safety Lanyard
