Hey I know I haven't been posting much lately, but you seem to have forgotten F16 altered has been using Carbon A class section mast for over a year.

It is a OZ built second hand A class mast, which I put Cedar timber cross ways up the inside covered with epoxy glue. This has made it bullet proof and brought it up to F16 min. wieght. I believe second hand A class Carbon masts are certainly a option for the individual F16 sailor, especialy as some are now considered to heavy or stiff for A's and anything other than a Fibrefoam is considered not good enough in OZ for most A sailors, meaning there are some second hand ones around. Saarbergs (European made) and Applied Composites (OZ made as used on Altered) are the non popular ones I have heard of.

There is also a modified Taipan 5.7 getting around with what looks like a A class section carbon mast on it, I think it was built in Sydney. If it is strong enough for the 5.7 it would certainly handle a F16.

Regards Gary.
