I've been doing some recording videos, and I get strange questions, and one email asked what the things are they can just see in some of them - so at the end of this one, A Dolphin Jib makes a short appearance. I've had it for years and it was made in the late 70's and is the most amazing piece of real engineering - beautifully made, but now very rare, and many people have never even heard of them - from the Vinten days when everything was names after creatures of some sort - Petrels, Terns, Plovers, Dolphins etc etc.

Wow! I’ve no recollection at all of that at all. Or the event in that picture 16 years ago. Cheers.
