As far as an F16 mast not being capable of sustained reaching loads, this is the first I've heard and its concerning. Karl, is your plan to switch to an F18 section cut down to the appropriate height? Why would the carbon not be better? Carbon is usually stiffer and capable of sustaining higher loads for the same weight as aluminum. Would Falcon would build a tougher Carbon mast for you if you asked?
I'm planning on using an AHPC F18 mast cut down. Really hoping to score one with a damaged end due to shipping.
I could have someone build a carbon mast, but I feel a lot better about throwing away a $1500 mast extrusion, rather than a built up $4k carbon mast. Reason being I'm only going to use it for the one race. Unless I fall in love with distance racing it will be either sold at deep discount, or recycled. Really all I need is the extrusion, I'll rob everything I can off of the Viper mast. I'm also hoping that I can get the mast tuned in with out having to re-cut a main sail.
