Definitions

  • a further object of the invention is to provide a cross jet rudder for watercraft which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 2 there is disclosed a vessel generally designated 10 which includes a cross-channel 2 defined across the ship bottom 6.
  • pressure equalizing or steering water channels 5 and 5' extend from the outer skin side surface 1 directly into the water channel 2.
  • a cross jet rudder for watercraft comprising a watercraft hull having a steering water channel defined in said hull extending transversely from side to side below the water line thereof, a water pressure equalizing channel extending entirely below the water line and from the outer surface of said hull on one side of the watercraft directly adjacent the steering water channel and directly into the steering water channel at a spaced location from at least one end thereof and being normally filled with sea water, and propulsion means in said steering water channel for moving water through said steering water channel.
