Abstract

A nautical vessel eg a ship with a tunnel 3 through, at the side of, or under the hull, divides into two tunnels 4. A propellor 2 mounted at the end of 3 propels water through 4. Mechanical openings 5, 6, 7, 8, 9, 10, 11, 14 along these tunnels 4 are then opened or closed to propel the ship in any direction required. <IMAGE>

Description

A DIRECTIONAL PROPULSION NAUTICAL VESSEL This invention relates to a directional propulsion nautical vessel.

As is known most nautical vessels are propelled through the water by means of a propeller mounted in the stern and steered by a rudder behind this. This means of propulsion however is very uneconomical and the means of steering is very limited and virtually useless when the vessel moves astern.

According to the present invention a nautical vessel with the engine(s) placed in the forward section of the vessel Figure 1 number 1 with the propellers mounted on the front end Figure 1 number 2.

The vessel would be fitted in such a way as to have a tunnel below the waterline from the bow Figure 1 number 3 in which the propeller(s) is fitted Figure 1 number 2. Aft of the propeller(s) the tunnel would divide into two tunnels Figure 1 number 4 built along the side, underside or through the vessel Figure 2 number 1, Figure 3 number 1, Figure 1 number 14.

These tunnels would require nine openings. One at the bow Figure 1 number 5. One each side of the bow tunnel Figure 1 numbers 6 and 7. Two each side of the side tunnels Figure 1 numbers 8, 9, 10, 11. One at the stern of each side tunnel Figure 1 numbers 12 and 13.

Each opening would require an independantly opening and closing mechanical door.

By this means it will be seen that the vessel, with the bow tunnel door open Figure 1 number 5 and the two side tunnel stern doors open Figure 1 numbers 12 and 13 could be steered by rudder(s) Figure 1 number 14 in the conventional manner when moving forward all other doors been closed.

If the bow door Figure 1 number 5 where open engine going ahead and the two starboard side tunnels doors, Figure 1 numbers 8 and 9 where open all other doors been closed. The vessel would be propelled to port.

If the bow door Figure 1 number 5 where open engine going ahead and the two port side tunnel doors Figure 1 numbers 10 and 11 where open all other doors been closed then the vessel would be propelled to starboard.

If the bow doors Figure 1 number 5 where open engine going ahead and the side tunnel door Figure 1 number 8 and the side tunnel door Figure 1 number 11 where open all other doors been closed the vessel would spin on its axis to port or anticlockwise and vice versa for side tunnel doors Figure 1 numbers 8 and 10.

With the two stern doors Figure 1 numbers 12 and 13 open and the bow tunnel port side door open Figure 1 numbers 4 engine running astern then the bow would be propelled to starboard all other doors been closed.

With the two stern doors open Figure 1 numbers 12 and 13 and the bow tunnel starboard door open Figure 1 number 6 engine running astern the the bow would be propelled to port, all other doors been closed, with the two stern doors open Figure 1 numbers 12 and 13.

The bow door open Figure 1 number 5 and the bow tunnel port side door open Figure 1 number 4 engine running astern the vessel would be propelled astern and to starboard.

With the two sterndoors open Figure 1 numbers 12 and 13.

The bow door open Figure 1 number 5 and the bow tunnel starboard side door open Figure 1 number 6 engine running astern then the vessel would be propelled astern and to port.

In this way with various configurations a vessel can be propelled in any direction by one propulsion unit.

Claims

1. A directional propulsion nautical vessel built with the propellor on the front of the engine and placed in the forward end of the nautical vessel.

2. A directional propulsion nautical vessel as in claim 1 whereby the propellor is fitted into a tunnel which is from the bow of the vessel to the propellor where the tunnel divides into two and runs the length of the vessel at each side, underside or through the vessel.

3. A directionf propulsion nautical vessel as in claim 1 and 2 where the tunnel has nine openings fitted with mechanical doors to control the vessels direction.

4. A directional propulsion nautical vessel as in previous claims which can be propelled in any direction by one one propulsion unit.
