An A class rig on a uni F16 should be very nice. Two up would perhaps be more load than the mast was designed for. We discussed this some time ago on this forum I believe as part of the "uni vs two-up" performance thread.

Consider "Rocker" C-class who was not faster than the other C-Class boats http://www.stevekilling.com/SteveKilling_CSYS2009.pdf


It still remains to be seen where development will go. Interesting time to watch and even perhaps play a bit.
