Wake shaping apparatus and related technology
The invention provides an apparatus that attaches to a hull of a boat to disrupt water flow around the hull such that a wake created behind the boat is larger, differently positioned, and/or differently shaped. In some embodiments, the apparatus is removably attached to the hull by one or more suction cups. The wake shaping apparatus can include a blade and be configured such that an angular orientation of the blade is adjustable. In certain embodiments, the wake shaping apparatus is inflatable.

2. The wake shaping apparatus of claim 1 , wherein the blade projects away from the base.
3. The wake shaping apparatus of claim 1 , wherein the blade has a width greater than the maximum width of the base.
4. The wake shaping apparatus of claim 1 , wherein the base and the blade are attached to each other removably.
5. The wake shaping apparatus of claim 1 , wherein the blade has a mount structure that projects outwardly from a face of the blade.
6. The wake shaping apparatus of claim 1 , wherein the wake shaping apparatus is configured such that the angular orientation of the blade can be adjustable by pivoting the blade about a pivot axis that is parallel to the axes along which the posts extend.
7. The wake shaping apparatus of claim 1 , wherein the suction cups remain in a constant plane when the angular configuration of the blade is adjusted.
8. The wake shaping apparatus of claim 1 , wherein the plurality of suction cups comprises two suction cups, such that the wake shaping apparatus comprises two levers, a first of the two levers when in the second position having a free end pointing upwardly away from the base, and a second of the two levers when in the second position having a free end pointing upwardly away from the base, and wherein the first of the two levers when in the first position has its free end pointing in one direction, whereas the second of the two levers when in the first position has its free end pointing in another direction that is opposite said one direction.
9. The wake shaping apparatus of claim 1 wherein, rather than the base and the blade being attached to each other removably, the base is permanently affixed to the blade.
10. A wake shaping apparatus comprising a base and a blade, the base having first and second end regions and first and second side regions, the first and second side regions extending between the first and second end regions, the base having opposed top and bottom sides, the wake shaping apparatus configured such that an angular orientation of the blade is adjustable, wake shaping apparatus further comprising a plurality of suction cups on the bottom side of the base, each of the suction cups having attached thereto a post, with each such post attached to a center of a respective one of the suction cups and extending outwardly therefrom along an axis, such that the suction cups have respective posts attached thereto and extending outwardly therefrom along respective axes, wherein each suction cup is coupled to a respective lever such that each lever is operable to activate and release suction for a respective one of the suction cups, each lever having a first position and a second position, such that when each lever is in the first position each suction cup is in a locked configuration, and when each lever is in the second position each suction cup is in an unlocked configuration, wherein the base comprises a pivot connection between the first and second end regions, the pivot connection comprising a ball joint.
11. A wake shaping apparatus configured to be attached removably to a hull of a boat so as to disrupt water flow around the hull such that a wake created during operation of the boat is larger, differently position, and/or differently shaped than when the boat is operated without the wake shaping apparatus attached to the hull, the wake shaping apparatus comprising a blade and a base that has opposed first and second end regions and opposed top and bottom sides, the wake shaping apparatus further comprising a plurality of suction cups on the bottom side of the base, each of the suction cups being part of a suction cup assembly that further includes a post, a pin, and a lever, whereby the wake shaping apparatus includes a plurality of posts, a plurality of pins, and a plurality of levers, such that each suction cup has attached thereto a respective one of the plurality of posts, each post has a hole therein, each lever has a hole therein, and each pin is received both in the hole in a respective one of the plurality of posts and in the hole in a respective one of the plurality of levers, wherein the base of the wake shaping apparatus has first and second side regions, the base has a maximum width, measured from the first side region of the base to the second side region of the base, and each suction cup has a diameter that is substantially equal to the maximum width of the base, the wake shaping apparatus further including a lanyard assembly comprising a float and a float line, the float line configured to be simultaneously attached to both the base and the float, such that the wake shaping apparatus is configured to float in a body of water, the wake shaping apparatus having a lanyard eyelet configured at the first or second side region of the base, wherein the lanyard eyelet is adjustable between a first position and a second position, such that when in the first position the lanyard eyelet is at the first side region of the base, and when in the second position the lanyard eyelet is at the second side region of the base.
12. The wake shaping apparatus of claim 11 , wherein the float line is configured to be attached to an opening of the lanyard eyelet having a top open side exposed at the top side of the base and a bottom open side exposed at the bottom side of the base adjacent to an outer perimeter of one of the plurality of suction cups on the bottom side of the base.
13. The wake shaping apparatus of claim 11 , wherein when the wake shaping apparatus is attached removably to a hull of a boat the opening of the lanyard eyelet to which the float line is configured to be attached is spaced apart from the hull by the plurality of suction cups such that a resulting clearance between the hull and the opening facilitates attachment of the float line to the opening of the lanyard eyelet.
14. The wake shaping apparatus of claim 11 , wherein the float is a closed foam material.
15. The wake shaping apparatus of claim 11 , wherein the float has a cylindrical configuration with a dome-shaped leading end.
16. The wake shaping apparatus of claim 11 wherein, rather than the base and the blade being attached to each other removably, the base is integral to the blade.
17. The wake shaping apparatus of claim 11 , wherein the float line comprises a rope attached directly to both the float and the lanyard eyelet.
