Surf hull with dual surf side

Abstract

A towboat hull configured to create a wake shape for wake surfing. The hull sides can create a symmetrical idle side dual wake as the towboat travels through the water. Controlled shaping of the wake is achieved by a flared hull sides that, when moving in a forward direction, propel the water away from the towboat to shape two idle side surf wakes simultaneously on each side of the boat. The improved towboat hull will create the improved dual wake shapes desirable for wake surfing, allowing wake surfers to surf both sides of the wake at the same time.

1 . A towboat hull, configured for wake surfing, comprising:
 a hull side that is flared towards a transom of the towboat and is nonparallel to a centerline of the hull, such that a transom width is greater than a midship beam width of the towboat hull; and   a running surface having at least one chine.   
     
     
         2 . The towboat hull according to  claim 1 , wherein the hull side terminates above the chine. 
     
     
         3 . The towboat hull according to  claim 1 , wherein the hull side terminates coplanar with the chine. 
     
     
         4 . The towboat hull according to  claim 1 , wherein the hull side is modular and is operably affixable to the towboat. 
     
     
         5 . The towboat hull according to  claim 1 , wherein the transom has a transom width that is at least about 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19% or 20% larger than a width of a midship beam. 
     
     
         6 . A method for shaping a wake, configured for wake surfing, at a side of a towboat, the method comprising:
 obtaining a towboat comprising,
 a left hull side and a right hull side that are each flared towards a transom of the towboat and that are each nonparallel to a centerline of the hull, such that a transom width is greater than a midship beam of the towboat hull; and 
 a running surface having at least one chine; and 
   moving the towboat in a forward direction at a speed that causes water flow across the left hull side and the right hull side to be propelled away from the sides of the towboat,   such that, when the water is propelled away from the towboat, it forms a wave shaped for wake surfing.   
     
     
         7 . The method according to  claim 6 , wherein the left hull side and right hull side terminate above the chine. 
     
     
         8 . The method according to  claim 6 , wherein the left hull side and the right hull side terminate coplanar with the chine. 
     
     
         9 . The method according to  claim 6 , wherein the left hull side and the right hull side are modular and are operably affixable to the towboat. 
     
     
         10 . The method according to  claim 6 , wherein the transom has a transom width that is at least about 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19% or 20% larger than a width of a midship beam.
