13:30 1 hour Wind: NE 7/12 kts
Board: JP Super Lightwind 90 - Deboichet R14 63cm
Sail: North S-Type 9.5 - North Platinum(13) 490cm - HPL Carbon Race 200-285
  (machine translated in 2023) Wind minimal, the 63cm didn't feel too small. Could plan easily, but board stuck, didn't run loose. Boom higher, mast foot to the rear, that helped a little, but it didn't really want to loosen up yet, maybe just too little wind.
There was also a difference between starboard and port, was not comfortable on the board on the left. Seemed like the fin is no longer straight in the box, or the box has a side clearance or something.
14:30 1 hour Wind: NE 8/16 kts
Board: JP Super Lightwind 90 - Select S11 61cm
Sail: North S-Type 9.5 - North Platinum(13) 490cm - HPL Carbon Race 200-285
  (machine translated in 2023) First time with the S11. Outhaul on upper eye. Vin seems to give more lift than the Deboichet 63cm. Had found the trim reasonable now, board started to loosen up nicely. Was also better, although I was still not quite comfortable on the left side, take a good look at the foot strap and put it on again. Wind increased rapidly, and ended up with when overpowered, the S-Type over max trimmed (outhaul again in lower eye). Board still stayed neatly on the water. Due to planned jibberish, the strong winds also went quite well.
