Diving update.
I can confirm that a dry suit in a swimming pool, is poorly named. I have never sweated so much in rubber, since a party in...ahem, well that's another story. I came out drookit !
It was really good though, and totally different from the buoyancy jacket. It was rather bizarre trying to control the air in the suit, and I'm glad the training instructors paid close attention to me, as I went foot end up several times. I have never been so scared of a potential fart since a poor curry in the early 90's.
Tell you what though Bill, fair play to anyone who does that day in day out. Kitting up is a task in itself, and I ended up with two women undressing me. Which sounds fine until I tell you that both of them said "Keep a hold of your shorts", literally in unison. I daren't mention how they slagged my snorkel!
So it's theory in a fortnight and then, I think, it is into the open water. My advancing years allows me a bit of trepidation in this. I may have to paint "help" on the soles of my boots.
Great fun.
