Kirt,
Yes, I'm pretty sure the "lighter" Superwing is what Antony is talking about. I've never had one but I was told the difference was somehow achieved during the Anodising process. Don't know if this is true. Don't even know if it is achieveable this way.
I expect that now adjustable spreaders are being used the need for a softer section for cat rigged boats is diminished.
I think it is much better having a single uniform section that you know will be strong enough to take a heavy sloop rig crew and have enough adjustment to tune for a light cat rigged crew.
Unfortunately I've been too busy to do much on the reacher/spinnaker front.
The new boat is coming along slowly but I'm very happy with how it is going.
Problem is, I enjoy the work so much I tend to take my time with it and just enjoy myself. As soon as I have to do it to a schedule it becomes a job and the fun goes out the window..
If I took time out from sailing I would progress more quickly but "one sail you miss out on is one you never get".
Hope you enjoy your Christmas and New Year festivities.
Phill
