thanks, awesome tips. lots to practice now!@flyinggorillaI've watched your videos and really like what you do. You should be proud. I have noticed your leeward board let go from time to time myself and think it is too much. I have wondered if it is because you have what I think are the original F1 boards or technique. You already have good feedback on the boards and set up so I will focus on the latter.
I don't see you moving your front foot or body much and would start there with more adjustments to be able to control pitch of the boat. You are too rigid. You can even steer with your back foot as the boat is so easy to rotate on the foils. Watch the videos of the most recent Worlds and you will see people being very active on sheet and body placement and footing. It was required to be super active in body movement and steering to get through the chop at Houston Yacht Club and the purpose of all the movement is to keep the leeward board loaded evenly, not overloaded or out of the water. The Nacra 17 sailors are tremendous in this respect as they run forward and aft as I guess those boats are difficult to sail well and can fall off the foils too.
It will take some practice but I think you can get fewer falls off the foils in this way and it will give you a lot of satisfaction to do. Nicks and foil finish is important but your boards look to be working well and are just losing grip, something you can help avoid with your steering, trimming, and body weight to keep the boat a little lower in the water when there are waves. And of course keeping the boat level is critical. I see you heeling just before the first fall and that leads to you losing pitch control and that along with the heeling increases the load on your leeward board which increases the difficulty of keeping flow attached to it.
The second fall looks to be after you turn up a little, maybe due to a puff. Again the boat pitches up as you turn and then the boards go above the knuckle and then lose grip and ventilation begins.
I try to minimize footing and move body weight forward/aft as needed. But as you point out not agile enough. It seems even when just sheeting in 30cm, one needs to move body weight forward at the same time. Consequently that's why I often lost grip in the past when sheeting-in quickly to not lean windwards, as this reduces the forward pressure, letting the foils go above the kink. Got it. Thx!
