This is getting crazy. It is always gangs that seem to be the perpetrators. And the police are pretty useless to defend. That is a tricky maneuver to say they were the police.
Down here you get to know that the police don't do much, so they are unlikely to come out to your boat ever, especially not at night.
I'm sorry another couple had to go through this.
I guess lots of lights outside and an airhorn, might scare off the bad guys and not the police. ANother reason people should keep their radio's on during the night. Police will respond to
VHF, bad guys wont. Plus you can
radio fellow cruisers to shine a spot on you.
