Something wrong with the DB, could not add the Hurricane fin properly. 

Tried 3 fins, Hurricane SRD33, Hurricane SpeedSlalom 34 and Sonntag SLpro 32 F4.3. With the gusty winds the Hurricane SS34 was nicest to sail and fastest. 

Fucked up speed in the first 60km because I did not have anough downhaul. The sail felt powerless und I first thought I put in too much downhaul. Beginner mistakes.... But it ended all okay.
