Mellenberg, Ther are private moorings in all the creeks on the Severn. All the Navy
ones are clealy marked. I have been using these moorings for 30 years. I have never seen a navy
boat on them. Once again these have been used for a swim, picnic or an ocasional overnight. It does not appear to be abused and I have never heard of anyone staying more than a day or two. I would be very supprised if one could get official permission to use them.
If you are looking for a mooring
check with the harbor master as they have some better pricing for longer stays. Not cheap
