Hi and welcome to the site.
Yachts are not the easiest of models to renovate as over the years the control and sailing methods have evolved quite dramatically.
The map shows you appear to be located in the Torquay area and I suggest you look in this sites Model Boat Clubs section and find a local club near to your location. Present your self at one of their sailing days and ask them if they would be prepared to help.
Hopefully a member on this site who is local to your area may be able to help. I am too far away in Sandbach.
Sounds like a nice yacht, are you able to post any pictures?
Dave
