All new, yes, nearly: The Bull got new rigging, very light Easy Rigging carbon cables and a new square cut mainsail. To say I was not happy with the outcome at the first day out on the water, is an understatement. Either the boat was slow or I did sail slow. The Taktick never showed more that 5.6kn when in the old configuration I got the speed up to 6.2 on a flat water upwind leg.
I have to do more testing with different rake and when I have calmed down I will write about what went wrong from the manufacturers side.
