Good idea Grant, I will carve some turns and make some mental notes as to where the rig is to go upwind.
When you say a low boom is it in the middle of the cut out or towards the bottom and how does this help you? _________________ Bryn Kaufman

Cut out location is fairly inconsistent across sails but on my Sailworks NX7.2 the top of the clamp is at about the middle. I'd describe it as between my armpit and top of my shoulder. |

Thanks Grant, for some reason I feel more comfortable when it is in the middle or a bit below the middle. I am not sure if it is changing my ability to get up on the foil in light winds from having it there. _________________ Bryn Kaufman

Makes no difference, it's personal preference, just like windsurfing.
Looking at Cal Cup gear, the range goes from 51" from bottom of mast base to 58", and from upper chest to chin heights..just like windsurfing. Being comfortable and dialed is the key. |

And if you are not comfortable & dialed in as obviously the OP isn't, shouldn't you move the boom height to find the comfortable & dialed in spot? Wouldn't that make a difference or am I missing something?

Just like windsurfing, specifics are only a rough guideline at best. We aren't built the same. Our gear isn't the same. And adjusting something "simple" as boom height affects and is affected by up to dozens of factors.
We've been slalom sailing for 35 years, and for the same sized sailor with the same sized sails, doing slalom, there are boom height differences of over 4".
Now you're talking about a basically 3 year old discipline without knowing any specifics, the variables are endless.
Yes, change it if it does'nt seem to work, but let's not pretend it's an absolute. |

I pump (with foil) less effectively with a higher boom, the opposite is true with a fin. Your milage may vary. |

Thanks Grant, I think a medium to lower boom will be my position from now on.
Now that you mentioned it I also feel my pumping was not as good with the higher boom. _________________ Bryn Kaufman

Wider board tail and longer wing span on a foil allows for better upwind/downwind angles. Naish design of foils and foil boards is very much opposite of that,so you will never have good angle per design. if you raced formula before it would help since technique is also very important, people that were good in upwind in formula now good at same on foil. If you never raced formula, it would take a while to figure out, there's no magic bullet for mast track, or boom position, the only common thing foot straps more on outside... |

Thanks Sergio, great points.
There are definitely some pros and cons with different size boards. I am now learning that. _________________ Bryn Kaufman
