Full power and really good test session. Mainly focused on 5.2's testing a new proto 2018 vs the current production. New sails are feeling really nice and balanced. Happy with speed considering I didn't make any speed runs. Was racing with World champ Twan and unless he was going easy on me, I think I was more or less the same..... through the chop... he did make a peak of 41kts at some point though, which is pretty impressive. Had a quick spin on the 5.6 too which also felt nice and balanaced.
