A boat with a controllable wake, including a boat hull with a propulsion system. A wake controlling device includes first and second plates with a bottom surface which is convexly curved between their forward and rear ends, and first and second mounts secured to the port and starboard sides, respectively, of the boat transom and securing the forward ends of the plates for pivoting about axes which are behind the boat transom and generally lie parallel to the plane of the aft boat bottom adjacent the first and second mounts. Plate controls extend between the transom and the plates to adjustably pivot the plates relative to the mounts. A plurality of generally triangular fins extend from the plates at substantially right angles to the plate bottom surfaces and extend at substantially right angles from the axes. Side plates are on the lateral edges of the first and second plates.

The invention claimed is: 1. A boat with a selectively controllable wake when propelled through water, comprising: a boat hull having a longitudinal center line between port and starboard sides, a transom at the aft end, and a hull bottom extending substantially continuously to the transom; a propulsion system for propelling the boat hull over a body of water; and a device for controllably adjusting the wake of a boat for skiers and wake boarders pulled by the boat, including a first plate and a second plate, each plate having a forward end and a rear end with a bottom surface which is convexly curved between said forward and rear ends, a first mount secured to the port side of the boat transom and securing the forward end of the first plate for pivoting about a first axis which is behind the boat transom and generally lies parallel to the plane of the aft boat bottom adjacent the first mount, a second mount secured to the starboard side of the boat transom and securing the forward end of the second plate for pivoting about a second axis which is behind the boat transom and generally lies parallel to the plane of the aft boat bottom adjacent the second mount, and first and second plate controls between the boat transom and the first and second plates, respectively, said plate controls being selectively adjustable to adjustably pivot the first and second plates relative to the first and second mounts, respectively; wherein said first and second mounts each comprise an angled plate including a mounting portion securable to the boat transom and a base plate having a bottom surface substantially aligned with the bottom hull surface at the aft end of the boat, wherein said pivot axes are defined on the respective base plates spaced aft from the mounting portion, said transom is curved, and said angled plate mounting portion is curved to substantially match the curve of the transom, and said hull bottom and transom intersect at a first angle, said mounting portion and said base plate of each angled plate intersect at a second angle, and said first and second angles are supplementary. 2. A boat with a selectively controllable wake when propelled through water, comprising: a boat hull having a longitudinal center line between port and starboard sides, a transom at the aft end, and a hull bottom extending substantially continuously to the transom; a propulsion system for propelling the boat hull over a body of water; and a device for controllably adjusting the wake of a boat for skiers and wake boarders pulled by the boat, including a first plate and a second plate, each plate having a forward end and a rear end with a bottom surface which is convexly curved between said forward and rear ends, a first mount secured to the port side of the boat transom and securing the forward end of the first plate for pivoting about a first axis which is behind the boat transom and generally lies parallel to the plane of the aft boat bottom adjacent the first mount, and a second mount secured to the starboard side of the boat transom and securing the forward end of the second plate for pivoting about a second axis which is behind the boat transom and generally lies parallel to the plane of the aft boat bottom adjacent the second mount, wherein said first and second mounts each comprise an angled plate including a mounting portion securable to the boat transom and a base plate having a bottom surface substantially aligned with the bottom hull surface at the aft end of the boat, wherein said pivot axes are defined on the respective base plates spaced aft from the mounting portion first and second plate controls between the boat transom and the first and second plates, respectively, said plate controls being selectively adjustable to adjustably pivot the first and second plates relative to the first and second mounts, respectively, a plurality of generally-triangular fins extending from said first and second plates at substantially right angles to the plate bottom surfaces and extending at substantially right angles from said first and second axes, side plates on the lateral edges of the first and second plates, and wherein the forward end of the bottom surfaces of the first and second plates in a first position are substantially aligned with the bottom surfaces of the base plates of the first and second mounts, respectively, and said plate controls are selectively adjustable to pivot said first and second plates down from said first position to increase the wake of the boat; wherein said transom is curved, and said angled plate mounting portion is curved to substantially match the curve of the transom, and said hull bottom and transom intersect at a first angle, said mounting portion and said base plate of each angled plate intersect at a second angle, and said first and second angles are supplementary.
