Hi Geoff - I think one of the problems may be that people with less experience of boat maintenance than you don't want to turn up if you're not there and then do the 'wrong thing'.
You let us have some time slots when you will be there to provide guidance as to what should be done next, with what tools and how.
As Chris says its pretty much opposite the entrance to The Oaks crematorium and on the same side as the Wyevale nursery
