@blocoloco, have you figured out the section of the f-one mast in the meantime?
Yes, I’m aware. I also saw that you are putting standard US Boxes into your boards which makes a lot of sense.
Note that the f-one masts all come with either KF or deep-KF box mounts and these mounts are not removable.
So in fact I would not recommend using f-one foils for eFoils as drilling the mast and the mount is difficult. I’m even thinking about switching to another brand for my eFoil.
I unfurtunately did not have time to test it before the Winter came in Canada…now, eveything is Ice! I will test it in May :O(
