A ski attachment for a wheeled insulated cooler which includes a left ski and a right ski and an upturned flange on each that is biased towards the inner edge of the ski. The upturned flange and a bracket are coordinated to allow a fastener to attach the bracket to the upturned flange. The bracket captures an axle and allows free rotation of the axle when the skis are connected to the axle. The bracket captures the axle to prevent the axle from being dislodged from the bracket on the ski. The ski is wide enough and long enough to provide sliding support for the insulated portable cooler over surfaces where wheels aren't useable.

Clamping mechanism for a ski, board, or other object that includes two linearly coupled jaws that increase or decrease the distance between each other. A lever controlling mechanism with an eccentric pivot that controls the movement of the jaws to increase or decrease the distance between each other, and that overcams in the locking position, thus tending to keep the mechanism closed or in the locked position. A clamp plate that is clamped between the two aforementioned jaws, such that it self-centers and limits the degrees of freedom in all directions relative to the mounted clamp.

A portable beach vehicle having retractable wheels that allow the vehicle to convert between a wagon for use on hard surfaces and a sled for use on soft surfaces, such as sand, is provided. The vehicle has a container for holding items to be transported by the vehicle. The container is mounted on a sled that can be used to manually pull the vehicle over soft surfaces. Each of the wheels can be deployed to convert the vehicle from a sled to a wheeled wagon that can be manually pulled on hard surfaces. When used as a sled, each of the wheels can be retracted to a position in which each wheel is entirely above the sled so that the wheels do not interfere with motion of the vehicle as a sled.
