This suggests that your mast may have been too far forward OR your sail
didn't have enough downhaul OR your boom was too high OR some combination of
the above. The mast foot should generally be centered about 52" or 53" from
the back of the fin (where it comes out of the board).

Windage on a 28-inch-wide board is significant, but less on the Allstar than
it would be on a conventional board of similar width. Compared to most
boards, the stance on the Allstar is actually farther forward relative to
the position of the fin. Still, there's less planing surface behind your
foot so the board is less likely to feel stuck to the water.

Since the 70 is efficient you should be able to carry a smaller sail than
you normally would for a given wind strength while sailing as fast or
faster.

   I just went out and measured it- it's at about 53"- a hair forward of
the center of the track. It is about an inch forward of where it was
when I'd demo'd the board. I was planning on moving it back, because I'd
had a smoother ride before.

   Should the mast track position shift with sail size, if so, roughly
how much?

   I'll try that too. I'm calibrated for rigging for sinkier boards.

   I appreciate getting advice right from the source!
