I've also bought a couple of Arrows that I can mix and match with rigs, I think the Arrow rig would more suit the F12 and I will play with those rigs on the F12 hulls before I buy F12 sails. Once I build the F12's though my plan is to have 6 cats here. As soon as someone says they want to buy one to sail here I will let them buy it at what it cost me. But at least I can strike while the irons hot. I think lightweight F12's, with homebuilt carbon masts will be very practical boats for my kids and enable me to travel with 4 boats, but I think my enthusiasm for building a new class went with the extra weight.
On a good note I'm hoping to get to Lake Bonney for their September winter series with the 5.8, two AC's and an Arrow quad stacked, what a sight
