Bridge openings

Bridge openings, especially on weekends, always have the potential to create difficult navigating situations. Question for the board. The bridge opening in this case is the narrow railroad bridge on a shark river inlet and assume for this question it's a strong incoming tide. There's a party boat outbound on the west side of the bridge (bow into the current) and smaller recreational boats inbound on the east side of the bridge (stern being pushed by the current). Assume that the party boat is first in line of the outbound traffic and there's a series of smaller recreational boats waiting on the inbound side. Question is in that situation when the attendant raises the bridge, who has right of way?
