The plan was to do an hour and alpha@500m at ZM around noon, and then go to Kwade Plaat for a speed session. Between 12h and 15h the wind turned out a lot lighter then predicted so I thought we also wouldn't have 30-40kn in the afternoon at the Plaat.

Did the hour with the new JP62 (first time) and Z SLM S 33cm. Wind was not strong enough and directing swung way too south from time to time... (upwind only 35km/u). It's a shame because I was really in the zone and didn't make any mistakes. All gybes fully planing, minimum speed during the hour was 9 knots. The new 62 really does gybe like a dream, soooo easy!

After the hour I switched to the JP54 with Z SLM S- 28cm (first time) and went to the outer dams. As soon as I saw +52 km/u alpha on my Suunto watch I started pushing as hard as I could. Ended up with 4 times above 53km/u and a massive 55,21km/u as max. The new SLM 28 is an absolute keeper, the fin performed amazing. Side note: max alpha on Suunto is 56,38km/u.

Only did 1 fast speedrun. Focussing more on runs and with the asy 25,5 I could have reached 75/76 avg but that was not the goal today ;-)

Congrats Brecht with your PR's, let's go to 70!
