Robbie,
Welcome. Visit the cruising forum for trips. Nothing is done on an official basis as per the following:-

But feel free to tag along with anyone and also feel free to arrange your own outings.
We are all of the same ilk and are pretty good to get on with. Don't worry everybody is friendly and after a season of tagging along you'll start to get to know people.
Regards Nick R.
