摘要： A fin for a slalom water ski includes a planar body with a convex leading edge and a slot proximate such leading edge. The slot has an arcuate front or leading edge and a wavy rear edge defined by alternating crests and troughs or projections which allow the fin to be smaller without compromising its ability to support ski acceleration. The smaller size allows the ski to be turned more easily. A line of small holes extending in a row proximate the leading edge of the fin body can achieve the same result.

摘要： A support structure for mounting an accessory assembly to a vehicle having a mounting surface defining a base mount and at least one brace mount includes a base having a connection portion being selectively connectable to the vehicle, and a support portion. The base is connectable to the accessory assembly. The support structure further includes a brace having a mating portion for engaging the support portion, and at least one arm extending from the mating portion toward the connection portion and away from the base when the mating portion engages the support portion. The at least one arm has a proximal end connected to the mating portion, and a distal end being spaced from the connection portion and being selectively engageable to the vehicle. The support structure further includes a lock selectively locking the mating portion to the base.

摘要： Boat propulsion assemblies are provided that can include: a water pump operatively coupled to a first conduit in fluid communication with one portion of a hull of the boat; and a water source in fluid communication with the water pump. Methods for propelling a boat are also provided that can include using a water pump to express water outwardly from one portion of a hull and propelling the boat.Propulsion assemblies may also be configured with: a first conduit extending from a first portion of a hull of the boat to a second portion of the hull of the boat; and a first pump operatively aligned along the first conduit and configured to convey water between the first and second portions of the hull of the boat. Methods for propelling a boat can also include: intaking water at a first portion of the hull of the boat; conveying the water to a second portion of the hull of the boat; and expressing the water at the second portion of the hull to propel the boat.Boat propulsion assemblies of the present disclosure can also include: an underwater member moveable in relation to the boat; and a conduit operably engaged with the member and configured to express water from a portion of the member. Methods for propelling a boat can additionally include expressing water from an underwater member to move the boat.

摘要： A water sport training device is disclosed comprising, in one embodiment, a raft having a distal nose portion and a proximal rear portion. The rear portion provides a pair of substantially spaced apart lateral pontoons and a first web spanning the space therebetween. A relatively rigid platform is positionable within the raft, substantially adjacent the first web. A buoyant seat portion is positioned substantially on a back half of the device between the pontoons and adjacent the platform. A tow rope attachment means is secured to the raft for selectively towing the device over a body of water. The device is configured such that a back half of the device has a center buoyancy sufficient for providing a stable surface to support the weight of a person while floating on water both at standstill and as being pulled through the water as by a boat.
