MARINE PROPULSION OR STEERING

Introduced: September 1968

Classification Context

Section:: PERFORMING OPERATIONS; TRANSPORTING
Class:: SHIPS OR OTHER WATERBORNE VESSELS; RELATED EQUIPMENT
Subclass:: MARINE PROPULSION OR STEERING

Description

B63H encompasses propulsion and steering systems for waterborne vessels, including propellers, screws, jets, paddle wheels, and rudders. The class covers the mechanical and hydrodynamic design of marine propulsion devices, steering mechanisms, and associated control systems. This includes arrangements for mounting propulsion units, thrust transmission, and directional control of ships and other water-based craft. Adjacent classes address hull design (B63B), vessel-specific systems (B63C), and related marine equipment, while B63H focuses specifically on the propulsion and steering functionalities themselves.
