Some thoughts after a session today.
Was totally skunked yesterday (was prepared to foil but it dropped to 3kts, so just not possible), and today had a similar bump in the afternoon, so I expected to be disappointed otherwise I would've brought a smaller board.
Ended up on the Blast again with a 6.3 freek, had it pretty dialed and was overpowered pretty much the entire time. Unexpected by a lot here, so surprised just about everyone out today.
I did try a carbon upright select 43cm fin for about 2 miles of a 35 mile day. It was just grabbing every single weed it hit and I could not get past 17kts board speed because they would cling to it, so I just switched to the 44cm MUF weed slalom (g10 not carbon) and stayed on it.
I tried to focus hard on getting my hand further back and sheeting in to force my front arm forward. It was helping, but I still think I need to improve on it. I also tried to bear off to pick up speed more before each jibe if I wasn't going to hit a kiter/windsurfer/winger. Good habits regardless of fin or foil. I don't know why I wasn't trying to do this more...
My best alpha is right below. I was trying to bear off more to get some speed before jibing, but on this side it was a bit choppier with swells. It made my stance a bit awkward and when jibing here I was bouncing a lot more and I think a few things came apart, especially where I was stepping with my old front to the back of the board, which upset the carve. I was better than last time, but still some kinks to sort out. I think I could be sheeting in more too.

Here's an example of the other end. I was bearing off pretty deep to get speed before jibing. I think though, because it was shallow, that I was getting slowed up a bit in the weeds down there. It seemed like I was losing speed a lot more than I should. But, there were other guys that were able to pull off planing jibes in this same area. So, I could definitely improve.

Maybe if I was jibing more in the middle of the route I could have had a cleaner spot with less weeds to slow me down? I don't know. I was also working on my stance a bit by forcing my front leg more straight. It seemed to help a lot more and I could also tell when my boom needed to be lower as I couldn't quite get in the groove and felt like I was pulling the sail too far from vertical. Example below.
I don't feel like editing jibe footage tonight but I may end up doing it later.
