I was thinking about this too because my nose was staying quite safely close to the water last time I sailed. My mast track was 1cm in front of the recommended settings, though next time I go out (hopefully my North will be fixed by then) I'm going for 30knts vMax, so I'm gonna run the track further back and see what happens.
I'm also going to experiment with some longer harness lines to get my rig further away and be able to run my boom higher.
My quest for >30knts has just begun, I just need good wind in my bay where the chop is less brutal, good rig board tuning and it's a done deal.
