One of the boats did a skid to leave, 180'd it and nearly into a pole. Managed to avoid damage however and drove off.
Then a new guy tried to do the same thing when leaving, I think something broke because then they parked in the servo accross the road for ages (untill it shut) and then drove off sounding unhealthy. Can't remember if that one was another boat or a 32.
Then the coastguard came round and bog lapped baskins for a while, then came up and pointed to my car "Does anyone here own this car?". Apparently they had reports of it "doing laps and being an idiot". Both of the afore mentioned cars were grey so I'm guessing the report said "grey skyline".
We said that we had been parking there all night and they said they would check the CCTV footage and took all our details in case the CCTV footage showed it was us. Then stayed a while while one of them ran all our details over the radio (background check presumably).
They were friendly enough (both members of the fairer sex), had a bit of a chat and said we looked like we were just sitting there not causing trouble, John mentioned we knew the owner, you guys must be used to getting pulled over a lot, etc.
Presumably the CCTV footage will show that we had in fact been there all night so I'm not worried. They didn't try to book us for 'parking up'
