I hope you manage to sort the sheeting. The system looks good on mine. As yet untested I have yet to buy any radio gear and batteries. I'm on holiday so I'll sort that when I return.
As for sailing it I live near Burnham on sea which is the home of Sedgemoor M B C . Not sure if there are any 6's there. As I walk around the lake often they are often sailing on Sunday mornings. DF's and IOM's.
