Aquatic towable device

Abstract

Disclosed herein is an aquatic towable device comprising a body, a towline connector, a rudder fin, and a steering apparatus. The towline connector is placed at one end of the body and above a waterline of the body when the device is occupied by a passenger. The rudder fin is attached pivotably to an underside of the body and placed toward the towline connector and positioned so at least part of the rudder fin will be underwater when the device is occupied by a passenger. The steering apparatus is attached to the rudder fin that pivots the rudder fin and is accessible from a top side of the body.

1 . An aquatic towable device comprising:
 a body;   a towline connector placed at one end of the body and above a waterline of the body when the device is occupied by a passenger;   a rudder fin attached pivotably to an underside of the body and placed toward the towline connector and positioned so at least part of the rudder fin will be underwater when the device is occupied by a passenger; and   a steering apparatus attached to the rudder fin that pivots the rudder fin and is accessible from a top side of the body.   
     
     
         2 . The aquatic towable device of  claim 1 , wherein the body is elongate. 
     
     
         3 . The aquatic towable device of  claim 1 , wherein the body is inflatable. 
     
     
         4 . The aquatic towable device of  claim 3 , wherein the body comprises a depression. 
     
     
         5 . The aquatic towable device of  claim 4 , wherein the body depression is sized to accommodate a passenger. 
     
     
         6 . The aquatic towable device of  claim 1 , wherein the rudder fin is attached to the body on a center line from the towline connector in the body's bow to a center point at the body's stern. 
     
     
         7 . The aquatic towable device of  claim 1 , wherein the steering apparatus comprises a steering wheel. 
     
     
         8 . The aquatic towable device of  claim 6 , wherein the device further comprises a second rudder fin. 
     
     
         9 . The aquatic towable device of  claim 8 , wherein the two rudder fins are placed on an underside of the body and spaced laterally and symmetrically from the centerline of the body. 
     
     
         10 . The aquatic towable device of  claim 1 , wherein the device has a fin placed along the centerline of its body between the center and the stern of the body. 
     
     
         11 . The aquatic towable device of  claim 1 , wherein the device has at least two fins placed symmetrically from the centerline its body and both fins being placed between the center and the stern of the body. 
     
     
         12 . The aquatic towable device of  claim 1 , wherein the rudder fin has a shape of a circle, an oval, an ellipse, a parallelogram, a square, a rectangle, a trapezoid, a trapezium, a triangle, a rhombus, or a combination thereof. 
     
     
         13 . The aquatic towable device of  claim 12 , wherein the rudder fin is positioned substantially vertically with respect to the underside of the body. 
     
     
         14 . A method of steering the aquatic towable device of  claim 1 , wherein the aquatic towable device is being towed by a boat with the towline through water, wherein a passenger in the aquatic towable device turns the steering apparatus to move the rudder fin to steer the device in a first direction. 
     
     
         15 . The method of  claim 14 , further comprising the passenger in the aquatic towable device turns the steering apparatus in the opposite direction to move the rudder fin in the opposite direction and steer the device in a second direction. 
     
     
         16 . The method of  claim 14 , further comprising the passenger in the aquatic towable device maintaining the steering apparatus and the rudder device in a plane along the midline of the device to maintain the device in a straight path.
