What does this mean?
Well put simply it's not just a case of turning up and dropping your anchor as the next thing you know, you will have someone official knocking on your cabin door asking you to move on if you don't have a pass or you are in the wrong place.
Should you choose to ignore that person you will probably then have a visit from the Police or military telling you to move!
So plan ahead and ensure you have done everything right before heading off to Weymouth.
The MCA gives this advice for people heading to both London and Weymouth.
