I have a very similar thing at my local ramp, especially late in the afternoon or night, it is a VERY popular Squid fishing spot, and coming into the jetty is a sea of light sticks attached to floats, and a dozen people all casting squid jigs, almost NONE of them will wind in for a boat, (they are fishing off the ramp and jetty) and there has been hundreds of altercations between fishermen and boat owners, now lets be 100% fair, there is no sign that says "no fishing" so... does that make it fair game for one and all (boaters and fisherman alike?) or does the boater have some sort of "right of way"? I know I have tangled up Squid jigs hundreds of times, and sometimes multiple jigs during a single retrieval.
