Hi Simon,

the Alloy Superwing mast and Carbon A masts are as similar in section as a Alloy mast can get to a carbon wing. That is the only comparison we have in OZ. Even a second hand A class carbon mast costs about the same as a new Alloy Superwing. I have been looking at this for a while, I was just lucky that the old A I bought and "Altered" to a F16 had a carbon mast with it, which after strenghthening which brought it up to weight was strong enough.

The other thing we want to avoid is what the Taipan Class used to have, which was cat rig and sloop rig masts of different strength and weight, because over time boats where bought and sold, changed from one up to two up and broke masts which wasn't good for the class. They now only make one weight of Superwing strong enough for Two Up. <img src="http://www.catsailor.com/forums/images/graemlins/tongue.gif" alt="" />

Finaly with no minimum weight people could put A class masts on F16, without strengthening some would certainly not be strong enough, they break on A classes <img src="http://www.catsailor.com/forums/images/graemlins/shocked.gif" alt="" />.
