Sorry Dave, but its pretty unlikely we will be there. We have been twice now and both times left in mid afternoon absolutely nithered.
Its a good venue for the event with the mix of models, sailing, boat trips and industrial archeology but it's very weather dependent. If it was held between May and September when the weather could be reasonably expected to be warm it would make wandering about between the different buildings quite pleasant. At the beginning of March its just too fragmented and too cold, not just outside but inside as well since most of the display areas are unheated.
Sorry to appear critical as I am sure the organisers work very hard to put on a good show, but at my age I like my creature comforts as well as model boats.
Regards
Gareth
