V1 was heading north in the Loxahatchee River under the A1A Jupiter Florida East Coast Railway (FECR) Bridge.  An unknown V2 was heading south in the Loxahatchee River under the A1A Jupiter FECR Bridge.  Both vessels were on a reciprocal course.  Both vessels were on the correct side of the channel per Inland Navigation Rules.  Both vessels were in the channel/fender system close to the draw span.  V1 was traveling in the same direction of the current.  The unknown V2 caused a wake that pushed V1 into the fender system, near the draw span.  The unknown V2 did not stop, nor exchange information.  V1's port side railing was ripped off and back.  V1 had brown transfer along the top cap and midship region. A piece of wood was found on V1 near the gas cap. The owner/operator of V1 and occupant were uninjured.
