It was less windy than expected and we wanted to try an hour attempt on our smallest 53 liter speedboards with 20 and 21cm fins. Didn't expect to do an hour like this, i think on the JP Speed 50 with a 23 fin gybing and going upwind is faster, this means there is some room for improvement. Also a little bit more wind will give us more speed. For the moment the fastest hour ever posted on this website, but maybe after Hans his posting not anymore. I think it will be very close.
