Abstract: A water management system including a first end point device in communication with a first fixture, the first end point including a first end point electronic processor configured to receive data associated with the first fixture and a first fixture identifier. The water management system also includes a non-transitory computer-readable medium storing instructions executable by at least one electronic processor to perform a set of functions, such as receiving the data associated with the first fixture and the first fixture identifier, associating the first fixture identifier with a first location classification and a first type classification, processing the data associated with the first fixture to organize the data based at least in part on the first location classification associated with the first fixture identifier or the first type classification associated with the first fixture identifier, and transmitting the organized data of the first fixture to a user device for display.

Abstract: A personal watercraft designed to advance suitably in a forward direction, to prevent an influence of side waves, and to incline to the turning center side when being steered by an operator from a forward direction to a turned direction. The personal watercraft includes a keel provided at a middle portion in the widthwise direction of the bottom of the body and extending from the bow to the stern. The keel is formed in an arc in the widthwise direction of the body. The keel is configured such that, at the rear half portion of the body, the center of the arc of the keel substantially coincides with the position G of the center of gravity of the body. On the other hand, at the front half portion of the body, the radius R2 of the arc of the keel gradually decreases in the forward direction.

Abstract: A sponson for a watercraft includes a nose; a trailing end; and a base extending between the nose and the trailing end; wherein the base is non-linear in shape in a direction from the nose to the trailing end. The sponson can include an outboard surface extending between the nose and the trailing end; wherein the outboard surface is configured to reduce the water pressure during cornering.
