The Sans Art Twin fins will provide you with down the line speed, drive and rail to rail feel that you get from traditional twin fin templates. It has a medium flex pattern and will generate speed better than your traditional fibreglass construction fins.
The Sans Art Twins also come with a trailer which can be used when you need a little more hold or stability.
Note: the image may not be an exact representation of the fin system. These fins are made to fit FCS boxes (two tab).
