Boat structure consists of vital components that enable it to float on water and travel without overturning. Each component functions to keep water out of the habitable space. The covering of the boat responsible for its buoyancy is called the hull. This encloses all structures in the boat and is covered on top by the roughly horizontal component called deck. On the deck, people can move safely and operate the boat. Both components comprise the main structure of most boats. Smaller boats do not have closely horizontal decking. Kayaks and canoes, for example, are only made of a hull, leaving the entire uncovered space habitable. Large ships have several decks, while boats can even barely have one. Below the deck is a space where passengers and crew can occupy a cabin. Small sailing boats have cabins enough to accommodate less than ten passengers. All boats have bows and sterns. The bow enables the boat to move against the water’s resistance as the hull cuts through. Its inclination reduces the amount of water washing through the deck and the top of the hull in increased sailing speed. The component that prevents water from permeating the hull is called the bulkhead. This is a walling installed within the hull. Behind the boat lies the stern, rear pointed corner of the boat. Most sterns and bows are pointed, while specially designed boats have flat to round sterns. The sharp edge of these components stripping through the lowest side of the faces of the hull is the chine. This is essential in maintaining the balance of the boat when it travels on water. Like the motor used, this component should be crafted in strict accordance with recreational craft directive, a standard in boat building. To protect passengers and goods from falling to the water through the side, a gunwale is provided. This is the longitudinal structural member locking up the deck on the hull. Its height should conform to the recreational craft directive to perform its task excellently. Other boats have handrails along the edge of the hull acting as the gunwale. Underneath the boat are components responsible for propelling the boat. The propeller attached to the rudder plate turns through a shaft powered by the engine build usually in a compartment in the deck. All these mechanical parts should observe recreational craft directive to achieve a quality promoting safety and efficiency.
