ABSTRACT:
Large objects which are difficult to handle, such as 14 to 26 foot boats, are secured to a base frame for shipment from the manufacturer to the dealer. The dealer attaches jacking wheel units converting the base frame into a dolly which may be readily wheeled into the dealer's show room or into a display area in a boat show. The base frame remains with the boat as a pallet until it is launched, supporting the boat substantially at floor level for most effective display. The wheel units are attached only for movement into or out of a display area or the like and are then removed for use on another base frame and boat.
