A Dolphin striker is a small vertical or near vertical spar spanning between the bowsprit and martingale providing tension to the latter to allow it to support the sprit and the rigging and sails it carries.[1]

On a catamaran such as the Tornado and the Cobra where the mast is stepped on a beam between the hulls the dolphin striker provides support for the beam in order to support the mast load.[2]
