BOATBUILDING,Hulls of Iron and Wooden Ships,1894 Antique Wood Engraving

Historical Collectible Art Print

Boat building, one of the oldest branches of engineering, is concerned with constructing the hulls of boats and, for sailboats, the masts, spars and rigging.Each part of the hull has a different name and purpose: * bow - the front and generally sharp end of the hull. It is designed to reduce the resistance of the hull cutting through water and should be tall enough to prevent water from easily washing over the top of the hull. * bulkhead - the internal walls of the hull * chines - are long, longitudinal strips on hydroplaning hulls that deflect downwards the spray that is produced by the hull when it travels at speed in the water. The term also refers to distinct changes in angle of the hull sections, where the bottom blends into the sides of a flat bottomed skiff, for instance. A hull may have 2 or more chines to allow an approximation of a round bottomed shape with flat panels. It also refers to the longitudinal members inside the hull which support the edges of these panels. * deck - the top surface of the hull keeps water and weather out of the hull and allows the crew to stand safely and operate the boat more easily. It stiffens an enclosed hull. * gunwale - The upper longitudinal structural member of the hull. Cannons were bolted to this in the earliest gun armed warships. * keel - the main central member along the length of the bottom of the boat. It is an important part of the boat's structure which also has a strong influence on its turning performance and, in sailing boats, resists the sideways pressure of the wind * keelson - an internal beam fixed to the top of the keel to strengthen the joint of the upper members of the boat to the keel * rudder - a steering device at the rear of the hull created by a turnable blade on a vertical axis * sheer - the generally curved shape of the top of the hull. The sheer is traditionally lowest amidships to maximize freeboard at the ends of the hull. Sheers can be reverse, higher in the middle, to maximize space inside or straight or a combination of shapes. * stem - a continuation of the keel upwards at the front of the hull * strake - a strip of material running longitudinally along the vessel's side, bilge or bottom * transom - a wide, flat, sometimes vertical board at the rear of the hull, which, on small power boats, is often designed to carry an outboard motor. Transoms increase width and also buoyancy at the stern. PRINT SHOWS THE HULLS OF IRON AND WOODEN SHIPS
