A rack for transporting personal pontoon watercraft. The rack has an anchor member which inserts in a standard trailer hitch receptacle and a support structure to which the watercraft is attached. Pivoting embodiments also have a pivot hinge which provides for the support structure to pivot between a down position for loading and an up position for transport, and a support brace which secures the rack in an up or transport position. The pivot hinge attaches the bottom end of the support structure to the rear end of the anchor member. The support structure includes one or more pairs of cradles into which the deck of the watercraft is slid which hold the watercraft in a vertical position for transport.
