Abstract

A vessel having sides 1 formed in flat parallel planes comprises a box-like hull with a funnel shaped opening 2 in the front leading to a tunnel 4 enclosing a propellor or turbine to drive the water in jet form along the upwardly-sloped bottom of the vessel channelled between two fins 6. The vessel is intended for inland waterways being free from bow wave and wash. <IMAGE>

Description

INLAND WATEPWAYS VESSEL This invention relates to a vessel free from bow wave and wash being suitable for inland waterways where bank erosion is a major problem.
The normal ship design have bows tapering to a knife like edge to cut through the water, the displaced water creates a wave that erodes the banks.
This vessel is of a rectangular boxlike shape the sides being a perfect flat plane giving no water disturbance other than that caused by frictional drag, the flat front of the vessel is cut away from just above the waterline to a point along the keel in the form of a funnel 2 the sides of which taper back from the leading edge of the sides 1 to join up with a short tunnel 4 in the centre of the bottom of the vessel, this tunnel 4 houses the propeller, turbine, or any form of unit to propel the water through the tunnel 4.
Under this arrangement the leading edge of the sides 1 become a stem 3 with the water displaced being directed to the centre of the vessel and being drawn through the tunnel 4 by the propulsion unit, When the vessel is under way the water entering the funnel 2 is guided to the tunnel 4 where it is propeled out of the exit 5 at this point the flat bottom of the vessel slopes up to the waterline at the stern preventing stern drag, the sides 1 of the vessel remain at the same depth thus forming a fin 6 on each side guiding the water flow along the bottom of the vessel as the pressure builds up the sloping bottom tends to assist the vessel along, as the jet drive takes place amidship the flow of water is spread across the bottom of the vessel smoothing out the turbulance, any air sucked into the tunnel 4 or released from the water by compression rises to the bottom of the vessel and helps to lubricate the vessel through the water.
this vessel having a square deck is suitable for the unloading of containers or other types of cargo ships in bays, harbours, and delivering direct to riverside factories ,or in the leisure class cabin cruisers designed with large sundecks and large square cabins.

Claims (5)

1 A bow wave and turbulance free vessel comprising of a box like hull, a funnel shaped opening in the front leading to a tunnel enclosing a propeller or turbine to drive the water ir jet form along the vessels bottom channelled between two fins the sides of the vessel being flat parallel planes.
2 A bow wave and turbulance free vessel wherein funnel means a cut away section between the leading edges of the sides to just above the water line forming two stems guiding the water to the centre line of the vessel.
3 A bow wave and turbulance free vessel as claimed in claim 1 or claim 2 wherein a short tunnel is formed along the centre line of the vessels bottom this tunnel providing the propulsion jet.
4 A bow wave and turbulance free vessel as claimed in claim 1 or claim 3 wherein a power unit drives a propeller or turbine in the tunnel drawing the build up of water from the funnel and creating the jet, this suction reduces the wave pressure , in doing so reducing the tise and full of the vessel.
5 A bow wave and turbulance free vessel substantially as described herein with reference to Figures 1-6 of the accompanying drawings.
