Fishermen are funny.
They rent the cottage next door, then zoom off at dawn to fish all day -- far away. Other fishermen (probably from far away) fish off the renters' dock!
Bass are
everywhere, waiting to be found.
In this case, it seems a reasonable approach would have been to simply move to the next property over.
The boat's size isn't mentioned, (is it a three-story?) and I don't know how a normal conversation can be had at 400-feet distance.
In these days of recreational chemicals, air-rage and road-rage, pass trouble-makers by.
