Mast Pre bend

It appears to me that there is very little pre bend in my mast as it is now. How much prebend should there be in an ARC21 mast sailing in Florida in 10 to 20 knot winds? I find that there is very little downhaul capability, is this a function of the lack of prebend?

Eric,
Tom was going to check on the amount of Pre-Bend for the 21 mast and get that information to you.
Regarding the downhaul, I am not totally sure what you mean by "very little downhaul capability" . We only use the downhaul to take the wrinkles out and flatten the sail a little if necessary. The 6:1 that comes rigged on the mast is more then adequate for this and additional purchase does very little other then stretch the mainsail out.

I am using past experience with a Hobie 20 miracle where down haul was very dramatic. I suspect that the H-20 mast section is less rigid, tht would explain why I ripped the head grommet out of my first main sail.....
