Removed upturned tips from stabilizer
Shim +1 or +1.5

What is the apparent difference in performance with the unaltered 400. Have you been able to also compare with the 360 or 340

I liked it a lot better than the stock 400. Much looser in yaw, giving the board a looser feel when playing in swell. Lower angle of attack allows moving the mast base back for a more responsive feel from the board. +1 shim gives the same angle of attack as the 340 and 360.

340 and 360 are another step in the same direction and what I ride now. These are thinner and have a bigger speed range. I currently use the 340 with 799 and 899 front wings windfoiling and the 360 with the 999 or 926 winging in lighter conditions.

Thanks, appreciate the advice, can you post a photo of the modified 400. I have and love the 340 and use with +1.5 shim with my 899, 926 & WO940.

Well you're right about the wallowing.

Went out in non ideal conditions with high tide, gusty, lots of disorganized chop and 7.0. Got it flying but didn't quite get it under control before crashing a few times. Definitely felt the looseness in yaw. I'll have to give it a go in flat water.

Finally got a stable flight and a jibe attempt on the 930. It was marginal with the 7.0, so I ended up switching to the 926. Pretty big difference in the lower end between the two from what I could tell, but maybe my pumping skills have decayed a bit during the summer.

It didn't seem to lose as much speed in that jibe compared to the 926, but I'll need more runs. More twitchy than the 926 for sure but cruising in light wind, it was fine in flat water. Was extra careful popping out of the rear footstrap on entry, but it ended up being not a big deal.

I think I need solid wind to really shake it out and get a feel for it. Too much time slogging vs. on the 926 today.

whats the 930 look like?

Shorter chord than the 926. Don't have a head-on pic at the moment but it looked similar.

Man. It's been a tough past month. Got some storm damage and missed most of the good wind lately due to hauling around flooring and preparing for contractors and insurance. Not what I prefer...

Got a small session in yesterday in a protected low tide area where it was flat and got a few runs in on the wing with my 7.0. Still taking some getting used to but once up the pumping feels more fluid and it feels like I have a lot more pitch control and sensitivity.

What surprised me even more was how quickly I felt like I dipped into jibes and came out with a lot of speed, just losing it when I touched water on the last quarter of the turn after the flip, but I feel the potential. Maybe next weekend if there's still wind.

5.6 conditions today. Went out first to tweak the sail settings on the 926 front then swapped in the 930. Had a few good runs of flight time with the 930, even had a good jibe with it on my second try, but the bottom was not there to get on foil. It may have been improved with better pumping on my part but I went with the 926 and immediately spent most of my time on foil again. Rode some waves and even had a good jibe out in the swells.

If it only had a touch more bottom end I would've stayed on the 930.
