You will almost certainly be questioned by the Port Police as you enter to make sure whether you need to check in or not.
Moor: anchor and tie back to the N quay, good holding, charges apply.
Ashore: very noisy as the main road runs along the quay and there are many bars around the harbour. Also the marina is much quieter if you want. Good shopping in the town and plenty of bars and tavernas to choose from.
