Wake-modifying device for a boat

A recreational sport boat comprising:

• a hull including starboard and port sides and a transom;
• and
• a pair of wake-modifying devices positioned aft of the transom, one of the wake-modifying devices being positioned on a port side of the boat's centerline and another of the wake-modifying devices being positioned on a starboard side of the boat's centerline, each wake-modifying device being pivotable between a non-deployed position and a deployed position about a pivot axis that is horizontal or inclined no more than about 35° from horizontal, each wake-modifying device including:
• a plate-like member;
• a first downturned surface at an inboard portion of the plate-like member, the first downturned surface lying in a first plane;
• a second downturned surface at a trailing portion of the plate-like member, the second downturned surface lying in a second plane which intersects the first plane;
• and
• at least one fin attached to a lower surface of the plate-like member,
• wherein in the deployed position, the second downturned surface is lower than it is in the non-deployed position so as to be able to modify the boat's wake.

• a plate-like member;
• at least one downturned surface at an inboard portion of the plate-like member, the at least one downturned surface constituting at least part of an inboard edge of the plate-like member and extending from a leading portion to a trailing portion of the plate-like member;
• and
• at least one upturned surface at an outboard portion of the plate-like member, the at least one upturned surface constituting at least part of an outboard edge of the plate-like member and lying in a plane that intersects the pivot axis,
• wherein in the deployed position, the trailing portion of the plate-like member is lower than it is in the non-deployed position so as to be able to modify the boat's wake.

• a pair of wake-modifying devices positioned aft of the transom, one of the wake- modifying devices being positioned on a port side of the boat's centerline and another of the wake-modifying devices being positioned on a starboard side of the boat's centerline, each wake- modifying device being pivotable between a non-deployed position and a deployed position about a pivot axis that is horizontal or inclined no more than about 35° from horizontal, each wake-modifying device including:
• a plate-like member;
• a first downturned surface at an inboard portion of the plate-like member, the first downturned surface lying in a first plane;
• and
• a second downturned surface located entirely within a trailing portion of the plate-like member, the second downturned surface lying in a second plane which intersects the first plane,
• wherein in the deployed position, the second downturned surface is lower than it is in the non-deployed position so as to be able to modify the boat's wake.
