WAKE-MODIFYING DEVICE FOR A BOAT
A recreational sport boat includes a hull, having 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 is positioned on a port side of the boat's centerline and another of the wake-modifying devices is positioned on a starboard side of the boat's centerline. Each wake-modifying device includes a plate-like member and at least one downturned surface at a trailing portion of the plate-like member. Each wake-modifying device is 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. When a wake-modifying device is in the deployed position, the downturned surface is lower than it is in the non-deployed position so as to be able to modify the boat's wake.

31 . 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 lower surface and a redirecting surface, the redirecting surface being positioned to intersect the lower surface and oriented in an aft and outboard direction, wherein in the deployed position, a trailing portion of the wake-modifying device is lower than it is in the non-deployed position so as to be able to modify the boat's wake.
32 . The recreational sport boat of claim 31 , wherein each wake-modifying device includes a fin and the redirecting surface is a surface of the fin.
33 . The recreational sport boat of claim 31 , wherein each wake-modifying device includes a downturned surface and the redirecting surface is the downturned surface.
34 . The recreational sport boat of claim 31 , wherein the redirecting surface of each wake-modifying device is angled between about 15° and about 75° relative to the pivot axis.
35 . The recreational sport boat of claim 31 , wherein the redirecting surface of each wake-modifying device is angled between about 30° and about 45° relative to the pivot axis.
36 . The recreational sport boat of claim 31 , wherein an angle between the redirecting surface and the lower surface is about 90°.
37 . The recreational sport boat of claim 31 , wherein an angle between the redirecting surface and the lower surface is between about 120° and about 135°.
38 . The recreational sport boat of claim 31 , wherein each wake modifying device includes a plate-like member and the lower surface is a lower surface of the plate-like member.
39 . The recreational sport boat of claim 38 , wherein an edge of the trailing portion of the plate-like member of each wake-modifying device is downturned and has a downturned surface and the redirecting surface is separate from the downturned surface.
40 . The recreational sport boat of claim 31 , wherein the redirecting surface is one of a plurality of redirecting surfaces, and each redirecting surface is positioned to intersect the lower surface and oriented in an aft an outboard direction.
41 . The recreational sport boat of claim 40 , wherein at least two redirecting surfaces of the plurality of redirecting surfaces are parallel to each other.
42 . 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 a port-side wake-modifying device positioned on a port side of the boat's centerline and another of the wake-modifying devices being a starboard-side wake-modifying device 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, wherein the port-side wake-modifying device and the starboard-side wake-modifying device are structurally asymmetrical about a longitudinal centerline of the boat, the asymmetry comprising differences in one or more of an upturned surface, a downturned surface, a fin, or a shape or size of the wake-modifying device, the differences including at least one of a presence, a number, a size, a shape, or an orientation of such features.
43 . The recreational sport boat of claim 42 , wherein at least one of the port-side wake-modifying device or the starboard-side wake-modifying device includes a fin.
44 . The recreational sport boat of claim 43 , wherein the port-side wake-modifying device has a different number of fins than the starboard-side wake-modifying device.
45 . The recreational sport boat of claim 42 , wherein at least one of the port-side wake-modifying device or the starboard-side wake-modifying device includes a downturned surface.
46 . The recreational sport boat of claim 45 , wherein the port-side wake-modifying device has a different number of downturned surfaces than the starboard-side wake-modifying device.
47 . The recreational sport boat of claim 42 , wherein the pivot axis of each wake-modifying device is horizontal or inclined no more than about 35° from horizontal.
48 . The recreational sport boat of claim 47 , wherein each wake-modifying device includes a plate-like member.
49 . The recreational sport boat of claim 48 , wherein a 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.
50 . The recreational sport boat of claim 48 , wherein each of the port-side wake-modifying device or the starboard-side wake-modifying device includes a downturned surface at a trailing portion of the plate-like member.
