I have a naish Hokua ..and have been playing around with fins ,three then four same day same size wave ...
It was a biggish day .a solid -6 foot ,a slow face ,but long bottom hand turns and a lumpy wave ..I was having trouble with the three fins as I was spinning out in the chop and lacked drive to get around the sections ..
so went in and changed .to 4 ...,It changed the board completely .....I was able to catch the waves easier .?
it was more stable ..and my turns had to be more longer ,but it did snap out of the turns faster and with more speed ,which was great .the extra speed sure did come in handy when racing the white wash ..even though not as loose ,it made up for speed ,and easier catch ,The surfers I where out with on 6.0 and 5-11 where're having a hell of a time trying to catch them...it was big and powerful but lumpy ...I caught twice as many ...even though I had to wait for the white water to clear ,to get back out .
4 fins are great in bigger surf and really glued the rear end to the face ..with speed ..it surprised me ...

anyone else found this ?
