Hi Paul

Why not post your link to the Pathe film on 'Seen Any Good Films, lately?" in the Yacht Club Bar forum?  That way people will be more likely to come across it once it disappears off the recent fora.

As for finding a boat in Cornwall who would be willing to take you sailing: not everyone regularly visits the forum, so your posting could easily be missed.  However, if you go here, you will find two links that might help, either from those willing to offer initial familiarisation on junks or from those seeking crew.  I'm sure of the 107 people listed, one or two should be in or around Cornwall.

Good luck!
