Marine bifurcated bottom ship

Abstract

The present invention relates to improving the structure of the ship by means of fitting plural screws in series on the identical shaft generated by the diesel engine to augment the velocity in proceeding operation and bifurcating the bottom of said ship to reduce the water pressure on the prow thereof.

1 . The bottom of the ship is bifurcated in the form of ditch which is inclined at a certain of angle to decrease the water pressure in front of the prop of said ship by means of drawing fluid into said ditch resulting in lifting the hull to turn to propulsion. 
   
   
       2 . The two screw are secured in series on the identical rotating shaft operated by the diesel engine to be supplemented with the force pushing blades of said front screw with the water pressure flowing through the inside of the water pipe and with the converging water flow brushed by among the blades of said front screw and other water flows divided on the prow flowing contour of the hull to strengthen the rotating force of the rear screw. 
   
   
       3 . The inclined ditch fitted at the bottom of said ship is liable to flow fluid consecutively preventing the dynamic stress from being accumulated to throw up at the center of said ship by the moment of the resultant force constituted with the water pressure on the front of the prow and the proceeding force generated by the diesel engine which is liable to render said ship be wrecked.
