Why is it up to the boat to move ? Both parties have equal access , this is a shared resource
I am not saying the either party is right or wrong but why do you feel the boat needs to move?
Me and my buddy were on anchor at the cap and these guys roll up and start casting and yelling at us that we needed to move because they needed room .... Was this ok?
It depends whether you guys gave them enough space.
You're right that everybody have or should have equal access ,that however doesn't mean that people should push their way in every gap between anglers.
I'm tired of other anglers that butt in so close that it impedes reasonable space for fishing enjoyment.
One should either get earlier or find some other spot.
Do you enjoy others interfering with your casting and drifting?
Some countries adopted rule that there is certain distance to maintain between anglers and this is stipulated in official fishing rules.
