Well I didn't get stuck on the cliff face.
The wind was buffeting me a bit, but the new fins made it a doddle, 5 hours in the tube before a cramp got me out and a bit of dancing sorted it.
Didn't get much as they had just chucked in thousands of little trout about 3 inch long. They were on to them like a free buffet and not much else.
But still happy with the effort.
Getting to enjoy this tube business.

Thanks for the rope tip.
