Parents of two drowned Duck Boat riders fight liability cap

A maritime law cap on liability should not apply in the case of two Hungarian students who died visiting Philadelphia when a barge struck their tourist Duck Boat, lawyers for their parents said on Sunday. Szabolcs Prem, 20, and fellow student Dora Schwendtner, 16, drowned in the Delaware River in July 2010, after the collision between the two boats, which occurred in full view of Philadelphia’s bustling Center City. Thirty-five other passengers on the duck boat survived. A duck boat is an amphibious vehicle, popular for tours in many cities, that can drive on city streets and plunge into water.
