It was very light and variable with the max no more than 7 or 8 knots. Top speed of the day was 14.5knots under main and jib.
I was very impressed at the speed upwind in particular, given the conditions.
Clive only launched the boat the previous day so it still has a load of potential to tap into.
My D/B is carbon and foam CNC cut and laminated under vacuum. It sticks out the case around 1700mm. There are a couple pics below showing the size of the D/B.
