I'm trying to get some training in leading up to some races next month. At the moment we have strong off shore winds and when paddling down the coast it is hitting me on the side. Not only am I having to paddle on one side only but sometimes even have to stop, back paddle on the other side just to stop the board always wanting to head downwind.
Is this constant struggle to track straight a technique problem, fin problem, board problem, sup problem or all of the above?
BTW I'm paddling on a starboard 12'6" cruiser with a big jimmy lewis fin on it (The black one)



Thanks for any tips

I'm currently using a Starboard 11'2" for downwinders with the standard drake fin that comes with it. Yesterday doing a downwinder in 25knotts and decent swell I found the board often spinning out. Would a larger fin help when doing downwinders? I have a large Jimmy Lewis fin that originally came off an 11+ foot cruiser, would this be a better downwind option for the 11'2"?
These are the 2 fins that I have
