Glad to hear you got the F-Type. The guys at Island Sports said they had sold it, I asked if it was to you.
Try starting with the front foot in the strap and the rear foot just in front of the rear straps on the centerline. You can start in the harness or out, I start in the harness, but if so you risk a catapult if things don't go as planned, so maybe better for you to start out of the harness till you get the hang of it. When you have the wind and want to get planing, be on a beam reach or below, and give it a couple of pumps, both the sail, and the rear foot on the board to pump the fin. It should "pop" onto the plane pretty quickly (keep pumping until it does). Once on a plane you can rotate your body out and get in the rear strap, and begin to rake the sail back as you pressure the rear foot against the fin, you can head upwind pretty quickly.
If you still are having troubles, do a session or two with the straps in the middle or inner positions, that's what I had to do to get used to it, but then go to the outer straps for max leverage against the fin as soon as you are comfortable.
It is a little different technique than the narrower boards, but once you get used to it, you'll love it. I ride the F-Type so much, I have trouble remembering what to do on a smaller freeride board!
I use this board for 9.5/8.5/7.3 winds and love it, as long as the water is pretty flat. If the chop is there, it gets pretty rough, time to go back to the smaller boards.
Good luck, see you soon if you go to Fogland.
P.S. For shallow water (like Fogland), I use the True Ames Shallow Water Weed fins, 51 cm for the 9.5 and 44 cm for 8.5/7.3, per Roger's input. Plenty of lift for planing, great pointing, rarely spins out (sometimes the 44 does with 8.5 overpowered).
