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.
