After a lot of reading on here and advise from members we decided to go with Horning Covers and how right you all were, what a fantastic job. they were unsure like us what the finished cover would look like as they have not done one quite like this before. with front and rear sections, roll up sides and back, and with roll up doors. its massive and has now given us a new room on the boat and weatherproof. thank you all for your advise.
