Abstract: A dredging system for removing material under a structure may include a barge body including a plurality of barge sections, each barge section of the plurality of barge sections configured to selectively be fully submersed or partially submersed to adjust a height of the barge body. A dredging system for removing material under a structure may include a winch system attached to the barge body and including a cable. A dredging system for removing material under a structure may include a drag beam coupled to the barge body via the cable and configured to vertically move via the winch system between a deployed position and undeployed position.

Abstract: An air vent for a floating board such as a paddleboard, which includes a tubular vent member that has an upper end and a lower end. A mounting supports the tubular vent member in a vertical orientation with the upper end of the tubular vent member protruding above an upper surface of the floating board. The tubular vent is mounted in a central zone comprising a central one third of the floating board, and along a crown positioned between a first side and a second side of the floating board.

Abstract: An article carrying scooter with unique folding and backpack carrying capability. A track extends from a bottom toward a top on a back face of a body. A scooter platform has a track engagement for moving along the track. By sliding the track engagement along the track, the scooter platform is movable between a substantially horizontal operative position extending rearwardly from the back face of the body and a substantially vertical stored position parallel to the back face of the body. The scooter has a lower support which projects forwardly from a front face of the body, supporting a body of a backpack from below and an upper strap engaging backpack support that engages straps of a backpack to prevent forward movement of the backpack.

Abstract: A rear drive assembly for a snow bicycle includes a body adapted to be supported by an axle which rotatably supports a rear wheel of a bicycle. An upper arm is rigidly affixed to and extends upwardly from the body. A lower arm is rigidly affixed to and extends at an angle downwardly and rearwardly from the body. A track tensioning and guide assembly is positioned at the remote attachment end of the lower arm. An extendible and retractable attachment member is positioned at a remote attachment end of the upper arm and is, preferably, attached to a seat post of the bicycle. As the bicycle begins to ascend a slope the attachment member retracts to maintain the track in ground contact and as the bicycle begins to descend the slope the attachment member extends to maintain the track in ground contact.
