Al I am really delighted for you I hope you have many many years of happy retirement doing what you want to do. As one who has over the years benefited from your sage advice I will as others will missed your experience and kindness, when I am in a 'fix'.
I am sure your experience will not be lost as i am sure you will find yourself 'messing-about' with boats and engines with maybe a few glances at the Rib net forums. If you ever find yourself up here in the 'frozen' north give me a call.
Once again all the very best to you have a good one,I can recommend it as I did it in February this year.
