Anyone riding a Wizard 105 and have a recommended Mast Foot/Track Position (range) for big (7.0) and small (4.0) sails?

I am still experimenting with mixed results. Started at 41.25" from Universal Joint Bolt to front bolt on the Foil Mast Box. This is the same as the Wizard 125 folks are doing. I use Infinity 84 and 76 foils in light-med wind.

The mast foot track range is large. Appreciate any insights.

Anything from 40" to 44" is a good starting point. Then tweak from there. Trial and error is a major thing in our sport.

Once you find what works for you, you got it. Now go out and foil your brains out.
