normal set up is for the 10am ferry, so you'll need to be at the terminal for around 930am to sort your bike, get ticket and car park etc.
it has to be the 10am ferry really as this allows us enough time to get to the pub, basically the guts of the ride is done before the pub, then we eat, drag out the thought of getting back on the bikes because the pub is at the bottom of the hill then roll back to yarmouth for the return ferry
