Boater Safety Course Chapter 1 Rated A hull body of a boat gunwales upper edges of a boat's hull-provide extra rigidity transom the cross section of the stern back light all around white light cleat metal fitting on which a rope can be fastened side lights red and green on the bow bow front stern back port left starboard right beam The width of the boat, measured at its widest point. Generally, the larger the ____, the more stable the boat. bilge A compartment at the lowest point of a boat's hull draft The distance between the waterline and the keel of a boat; the minimum depth of water in which a boat will float. aft The area towards the stern of the boat. forward The area towards the bow. freeboard The distance measured from the waterline to the gunwale. waterline The intersection of a boat's hull and the water's surface, or where the boat sits in the water. keel A boat's backbone; the lowest point of the boat's hull; provides strength, stability and prevents sideways drift of the boat in the water. planning hulls designed to rise up and ride on top of the water at higher speeds. displacement hulls . The combination of their weight and power means they move lower in the water, pushing water, rather than riding on top of it. Flat Bottomed hulls hulls are very stable, great for fishing and other uses on calm, small bodies of water. Round Bottomed Hulls typically displacement hulls, and are designed to move smoothly through the water with little effort. An example is that found on a canoe. One drawback is that it's less stable in the water and can capsize more easily. So, extra care needs to be taken when entering, exiting and loading these types of boats. V-shaped Hulls planning hulls, and are the most common type of hull for powerboats. Designed to plane on top of the water at higher speeds and provide a smoother ride through choppy water. Multi-Hulled These boats can have either planing or displacement hulls depending on the shape of hull and size of engine. These are some of the most stable on the water. They also require more room to steer and turn. Outboard Engine engines are mounted on the transom of the boat, outside of the boat's hull. These engines are used to both power and steer the boat. Inboard Engine engines are located inside the boat's hull. These are four-stroke automotive engines that have been modified for use on the water. These engines power a drive shaft that is connected to a propeller. They do not also steer the boat. Instead, they have a rudder or rudders that are located behind the propeller and controlled by a steering wheel. Stern Drive Engine engines use a four-stroke automotive engine mounted on the inside of the hull to power the boat. There is a drive unit used to steer the boat. To steer, turn the steering wheel, which then turns the drive unit, and determines the direction of the boat. Class A less than 16 ft Class 1 16 ft to less than 26 ft Class 2 26 ft to less than 40 ft Class 3 40 ft to less than 65 ft Capacity Plate includes the maximum number of adult persons, the maximum gross load, and the maximum size of engine, in horsepower, that your boat can legally carry. Maximum Gross Load the total weight your boat can handle, including people, equipment, stores, fuel, engine assembly and steering controls calculating capacity Number of people = vessel length (ft.) x vessel width (ft.) ÷ 15 150 lbs Maximum person capacity average weight Maximum Horsepower Calculation Boat length x boat width = boat square footage Overloaded it will sit low in the stern and will possibly be swamped by its own wake or another boats Overpowered very hard to control -twelve characters include: -manufacturer -five-character serial number -month and year of production -year of production Hull Identification Number (HIN) starboard transom HIN location? powered boat any boat propelled by the force of an engine
