You could try Gregor from Seaforce (http://www.seaforce.co.uk/) 0141 221 1070. They are based at the Tallship. He ran a PB2 course just for me so suspect he might do the same with VHF for you. If its in a month or so's time and he needs another "body" to justify it - I would be interested.
Polwart, I spoke to gregor today ( he also ran PB2 just for me ) and he is running a VHF course on the 9th of april. Dont know how many people are on it tho.
