Thanks Thom
My main concern was the extra mast height with our limited weight.I also sail the boat by myself under 7 knots and think I'll be in the air a great deal.I would only sail the 20 up to 10 to 12 knots these days as I'm a heavy windsurfer and also have a Tasar, which is a planning racing dingy from Australia.
The 20 has been through alot and is a telescoping rather than a fixed beam so it's walking a bit.
I don't race at all,I'm just into speed and I've never lost the rush when the spray starts kicking up.

My 20 has 6' racks that I built many years ago with the help of Randy Smyth.They can be transfered to the 22 as the dimensions are exactly the same between the cross beams.This should help a bit but when you mentioned the boat being alot to handle at times when the wind picks up, I get a little apprehensive.I'd have to add a third crew !!!

Thanks for your feedback.
