RedactedNarrative: On 8/30/15, I overheard the badge tende hailing a vessel on VHF 9 regarding a collision. I contacted the bridge tender who advised that a vessel (Makaira) had struck the bridge. I then responded to the scene. Upon arrival, I made contact with the vessel which was moored just north of the bridge. I spoke to the captain who advised that as they were traveling north on the river approaching the bridge, they were caught by the outgoing current which pushed them sideways. The vessel's starboard midship then struck the fender system on the southeast side. The vessel was able to maneuver back into the channel and proceed north. The vessel had damage to the side from the collision. The bridge had a piling damaged and signs bent. The captain advised of no injuries.
