Abstract: A recreational sport boat includes a hull, having starboard and port sides and a transom, and a wake-modifying devices positioned aft of the transom. The wake-modifying device includes a plate-like member and at least one downturned surface. The wake-modifying device is pivotable between a non-deployed position and a deployed position about a pivot axis. When a wake-modifying device is in the deployed position, the downturned surface is lower than it is in the non-deployed position so as to be able to modify the boat's wake.

Abstract: A temporary shelter having an inflatable, tubular base frame with inflatable, tubular wall support ribs fixedly attached thereto, the ribs converging to near an apex of the shelter. Flexible, water-resistant wall portions are fixedly attached to the tubular base and wall support ribs. The base frame, wall support ribs and wall covering form a domed structure when the base frame and support ribs are inflated.
