Re: What to do if someone hits your moored boat?
most county sheriffs have a marine division to handle conflicts . Go to the sheriffs office & fill out a police report with a statement from the person who observed it . If he refuses to respond it is akin to a hit & run in a car (a little different for boats). The sheriff can help guide you what to do next.
Also that contract you signed with the marina that says they aren't responsible , doesn't hold up when they act irresponsibly (like putting too wide of boats in too narrow an area).
