Jeff,

Mast: Depending on its age, it might be totally suitable. Weigh it and/or measure the stiffness as discussed around here somewhere and post the results. If its too light (not stiff enough) you can definately win some strength back by leaving the hounds up high and if need be adding some inner diamonds (they're a pain in the butt but the price is right).

Beams, obviously the beams are too short. Do you still have the beams and tramp off your T? These could be cut down to suit and you'd end up with a really stiff platform.

Foils: The dagger boards will be undersized as your F16 will probably be deeper than the A and will definately have more righting moment and a lower mast. However, A cats are usually designed with the boards providing most if not all of the hydrodynamic lift. If you move the boards fwd some of this lift will be provided by the rudders. You will of course have to rake these under further to reduce the weather helm. Alternately you could once again look to your T and use its rudders (if they still exist).

In short, between your two wrecks you definately have the majority of the bits needed for an F16.

On a side note can you call me on my mobile (0400 628 379) during the week to discuss delivery of your F12 bits.
