The better question is WHY put the HT mast on the Inter/Nacra 20? Did the stock telephone pole break? Are you thinking the more flexible rig will let you select better sails? Maybe you should order a new spinnaker and see what that does to your boat speed before getting the upwind sails/rig sorted?
It's an idea that was sparked when I remembered the ht/a-cat thread. But there is no close HT that I know of for sale. Just exploring options. Unfortunately I have a brand new set of sails that were just built for te 20 mast so it would probably mast more sense to stick with that.
