In some implementations, a stand up paddleboard (SUP) transportation apparatus to facilitate transportation of a SUP to and from a shoreline comprises a sled material and an adjustable attachment mechanism to temporarily attach the sled material to the SUP. The sled material has a top surface for supporting the SUP and a bottom surface for dragging over a ground surface, a longitudinal axis passing between a front end and a back end, and a latitudinal axis passing between a left side and a right side, wherein the longitudinal axis spans at least a portion of a length of the SUP and the latitudinal axis spans at least a width of the portion of the length of the SUP being supported. The adjustable attachment mechanism is able to join together to adjustably secure the sled material to the SUP and able to detach to release the sled material from the SUP.

An exhaust system for a combustion engine vehicle includes an exhaust pipe extending between an exhaust inlet disposed opposite an exhaust outlet. The exhaust inlet and exhaust outlet are in fluidic communication with one another. The exhaust inlet is configured to receive an exhaust gas produced by an internal combustion engine of the combustion engine vehicle. A second pipe has an air inlet extending from and connected to the exhaust pipe. The second pipe is configured to be in fluidic communication with the exhaust outlet. The air inlet is configured to receive an outside flow of air. The exhaust gas from the combustion engine vehicle and the outside flow of air captured by the air inlet when the combustion engine vehicle is moving forward are configured to be combined and to cooperatively exit out the exhaust outlet.

A surf craft includes: a body having a nose and a tail; a bottom surface extending from the nose of the body to the tail of the body; a channel formed in the bottom surface of the body, the channel including a channel entrance located towards the nose of the body having a depth that is substantially flush with the bottom surface of the surf craft, a channel exit having a depth such that a bottom surface of the channel curves from the bottom surface of the surf craft towards an upper surface of the surf craft, first and second opposing sidewalls. The first and second opposing sidewalls curve outwards along a substantial portion of the channel such that a width of the channel exit is wider than a width of the channel entrance.

The invention provides a solution to people who want to enjoy therapeutic exercises in water using body boards but do not yet have the necessary skills to maneuver themselves alone. This invention serves as a way of acquiring these skills through a body board anchored to a fixed position and leaving a reasonable amount of space for the user to freely move his/her body without interfering with the operation of the board.
