Greetings folks, from the wilds of Northern California USA.
I'm new here and very excited to read all the good information I've already seen. I am actualizing my dream to build a land sailer from recycled materials. (very California. The hull is a very aerodynamically slippery river kayak, shortened and reinforced. The front wheel and forks are from a 50 cc pocket bike. There is a very sexy looking 4" disc brake which I fancy because in the hull I can't brake with me feet when returning to camp. Rear wheels are Dunlop "mags" and tires at 3.50 x 8; beach wheels from a Zodiac inflatable. The rear axles are made from laminated downhill racing skis. The tips are removed and the tails cut off to provide two four foot units which are springy yet quite stable and only slightly heavier than optimum.
I"ll power the boat with a wind surf rig working against a "hound post", guyed three ways.

So, questions.

The deeply reclining position and requirement to cantilever the axles creates a space conflict. I'm considering angling the axles FORWARD, the opposite of the arrangement of a Fed 5 or Pac. Magic. The axles would mount under my head rest, and extend forward. Are there any physical (as in physics) demons that immediately come to the minds of the experts? Where does the real benefit come from angling the wheels like on a PM?

I have the choice to mimic the physical dimensions of either a Manta twin, or a Pac. Magic. Can anyone share anything about the proper location of the mast and support post? This is the basic configuration of an Ice Flyer except in my case the pilot is in the rear.

I hope this gets something started. I'll check back regularly to dialog. Thanks in advance. I'm excited that I have the opportunity for technical advice from the land of OZ! Way cool!
