Hi and welcome
Normally hire yards are reserved for hire boats but I think Faircraft Loynes may let you moor there if they have room and you ask nicely. I guess other yards may, at their discretion, again if they have room. Don’t try on a Friday or Saturday though! You can moor outside the Hotel Wroxham although there is a £10 fee overnight. I believe you can moor at the café, again a fee is payable. I have a feeling that you may be able to moor in the old Moores yard on a visitor basis but someone else may be able to advise on this.
I’m assuming that you are not able to get through the Bridge? Plenty of moorings through there if you can, Horseshoes and Viaduct moorings.
