Water Access Rights Question.

[Num70]

Hello everyone. I'm relatively new to this board and wasn't sure where to post. But it didn't really seem like a conservation post, so thought I'd try it here. Quick question: Can anyone really outline for me the water access rules in Massachusetts? A lot of people speculate and talk by word of mouth, but never really cite the exact law. Can anyone here do that? I tried a bunch new spots this year and had more property run-ins than ever. Now it's duck hunting season (for me anyway - I'm on the North Shore) and I've already had my first access run-in. Cops came and everything. The officer pretty much admitted that he REALLY didn't know the law. Just looking for some knowledge. Any insight is apprecaited. Thanks a lot.
