Mark, sorry it took so long to answer. For some reason I could not reply.
Anyway, in order to do this properly you need to have 2 sailmakers, 2 boat builders and a shop teacher. I figure that was just about enough brain to equal 1 normal person
Abbott's have a 40' mast trailer that we used. We put Pearson's boat on first ass first at a slight angle. We had his boat just on shop cart/cradle. Then our boat went on, on our trailer with the wheels off. it was bow forward and angled as well then pushed as far forward as we could to give the "yin/yang" look.
We then strapped the heck out of them. We had the Honour tin rig under the boats strapped to the trailer and Putz's carbon rig was up on his boat. I have been seeing a bunch of 5th wheel car haulers that I think would be awesome for trucking U-20's or Vipers around. I think you could get at least two on those if not three. You might look at that.
All this took about an hour and half to set up.
Worked very well behind the big diesel van. We did blow up some tires but that was a fender issue if I remember correctly. When Brad gets back from SD I will have him pipe up as well.
BTW, I have bought part of Dr. Mike's boat so that it will sail at the NA's.
Cheers
