Hi Daniel,

there was a thread on this a while back.

My theory is that if a foam sandwich A class can cope with minimal mods, a foam sanwich mossie certainly could with the same mods. The foam sandwich A class I cut up to make a F16 was not built anywhere near as strong as my previous foam sandwich Mossie, when you think about it, an A class is 2 feet longer than a Mossie hull and the bare hull weights are not much different, so the Mossie must be stronger. As mentioned transoms are closer to rear beam etc. helping to increase strength.

I think even on the new boats centreboard are still far enough forward, they are alot closer to the main beam than pre foiling A classes.

As for beams, I am no engineering expert. But there's not much to lose, I would be willing to take the risk. Do it and I'll be standing on the beach waiting to be second to sail it.
