AA62,
Tanks! Tanks, that is the answer! I have no doubt that the under wing tanks should have been fitted to the J to begin with. that would straighten things out just a little. and we all know every little helps. On cross over; the long J was as good as the short K, or was it the other way round?
I don't recall 22ft going out of the side doors in my time. Always out the back following boats or on the water course.
Look forward to seeing the snatch pics. I think I did see something like this in the archives at JATE years ago. VX275 sent me some Beverly similar sounding stuff a while back.
