B63B SHIPS OR OTHER WATERBORNE VESSELS; EQUIPMENT FOR SHIPPING (arrangements of vessel ventilation, heating, cooling, or air-conditioning B63J2/00; floating substructures as supports of dredgers or soil-shifting machines E02F9/06)
Introduced: September 1968
Description
B63B covers the structural design, construction, and equipment of ships and waterborne vessels of all types, including hulls, propulsion systems, steering mechanisms, anchoring devices, and onboard equipment for navigation and cargo handling. This subclass encompasses vessels ranging from small boats to large commercial ships, as well as specialized watercraft such as submarines, hovercrafts, and hydrofoils. It also includes safety equipment, ballast systems, and other apparatus integral to vessel operation and maritime transportation. Related equipment for shipping operations, such as loading gear and maritime safety devices, falls within this classification, while waterborne vessel engines are classified separately under B63H.

Glossary
Attitude The position of a vessel in relation to the horizontal plane. Bilge Part of the hull and corresponding compartment of a ship where the hull sides curve inward to meet at the keel. Bilge keel Bilge keels Longitudinally extending profile protruding from the outer surface of the bilge, for resisting rolling motion. Bulkhead Bulkheads An upright wall within the hull of a ship, separating hull compartments. Davit Davits A crane on the side or stern of a ship for raising and lowering loads, often arranged in pairs for lowering lifeboats. Fender Fenders A buffer to protect a vessel's hull from chafing or collision with a wharf or with other vessels. Keel keels A longitudinal beam around which the hull is built; a subsurface fin protruding from the hull to afford directional control and stability Lashing Lashings Fastening a movable body with a cord or the like. Mooring Securing a boat or vessel in a particular place, e.g. by tying-up or anchoring. Port ports A door, gate or closable opening. Shipping Ships collectively. Navigation. The act of putting persons or things onboard ship or transporting them by ship. Stability The ability of a floating vessel to remain upright or return to an upright position when disturbed. Trimming Adjustment or division of ballast and/or cargo to alter a vessel's draft or trim. The distribution of buoyancy and load. Winch winches A hoisting or hauling device comprising a driven rotating drum around which a rope passes
