A swim paddle system includes a substantially planar, rigid paddle having a first side for receiving a hand of a swimmer and a second side opposing the first side with a plurality of through holes extending through the paddle from the first side to the second side, the first side having a palm region for receiving a palm of the hand and a peripheral region for receiving a thumb, an index finger, a middle finger, a ring finger, a little finger, and a wrist of the hand. At least a portion of the paddle is transparent or translucent to allow at least a portion of the hand to cast a shadow as light shines through the paddle.

A hand cover apparatus with a tensioning mechanism that tensions a portion of the apparatus such that it is urged to retract to an open position, freeing a portion of the user's hand. Said system has one stationary piece and at least one additional piece that moves relative to it and can be triggered to free the hand by using only the hand to which it is mounted.

A sports device. The sports device includes a stem having a handle and a blade which is attached to the stem on either side of the handle may be used for operating gentle yet strenuous water sports

A swim paddle can include a low profile housing body including a hand surface and a water surface. The low profile housing body can further include a longitudinal axis that is parallel to the length of a hand of a swimmer and a transverse axis that is parallel to a width of the hand, wherein the longitudinal axis is longer than the transverse axis, and wherein the hand surface is adjacent to a palm of the hand. The paddle can further include a strap that can secure the low profile housing body with the hand of the swimmer. The swim paddle can further include an electronics package that can be affixed to the low profile housing body.

A resistance kickboard attachment is disclosed. When attached to a kickboard, the resistance kickboard attachment adds resistance while swimming with the kickboard. The resistance kickboard attachment includes a resistance pocket, with variable resistance provided by an adjustment of a rear aperture of the resistance pocket. The resistance kickboard attachment attaches to the kickboard with a transverse and a longitudinal strap. The transverse strap includes an adjustment on either side of the longitudinal strap which allows the longitudinal strap to be centered on the kickboard.
