Another big hand up for Jimbo!
He and I did our VHF instructors together and can vouche for his skills as a teacher.
Sarah Might be worth you giving Jimbo a shout to she if he can fit "your man in" as it were before Sept.
You might want to try Simon Hawkins on here, word has it that he is not to shabby either
Failing that you have Jon and his "dad" at Mendez Marine.
If you were all over my way I would offer my services but sadly your not.
Hope that does not add to the confusion too much for you both.
