A watercraft hull and gunwale mooring guard for attachment to a mooring structure to prevent abrasion damage to the contact surfaces of a moored watercraft. The mooring guard includes a stationary vertical guide rod that is attached at one end to a mooring structure at an spaced horizontal distance therefrom and extends vertically upward above the mooring structure. A traveler member is slidable attached to the guide rod which when movement of the water causes the watercraft to move up and down, the traveler in contact with the watercraft will correspondingly move up and down and thus prevent hull and gunwale abrasion, scuffing and damage to the watercraft.
