Small world mate. I also live in Caol about 200m past where John and Alistair live. I see them around almost daily, although I wouldn't say I was a personal friend. I was not aware that they had both been to sea.
I take it that you were at Gravesend together. I can get a message to them if you want. I am not sure if they are on the Internet.
Got stopped at the local shop yesterday by John. He apologised to me for not getting in touch with you. I was surprised because I thought he would have dropped you an email by now. He said that he will get to the local library soon and drop you a mail. I get the impression that he is not that familiar with the computer. I will remind him next time I bump into him.
