Diesel engines have doubtless great economical sdvantages, especially when used for marine propulsion, but at the same time entail some disadvantages ; firstly, the uneven torque developed, secondly, the huge dimensions required for larger outputs, etc. These can be completely solved by interposing the Vulcan hydraulic coupling and gear. Moreover, introduction of the mechanical reduction gearing permits favorable propeller revolution, and obtains a considerable gain in propeller efficiency. The purpose of this paper is to discuss the following advantages of the double Vulcan geared Diesel engines installed in a proposed single screw cargo boat, compared with several direct propelling ones, Such as ; -a) Smooth running, b) Less machinery weight, c) Smaller machinery space, d) Lower running expenses, e) etc.
