I posted an ad last night but no one helped me out, during the day i pondered the thought of putting four small fins on sides and one larger single fin in back. Is this over kill, i really like the whole retro styles anything other than just plain old thruster three fin. the board is 6’0x10"x18"x13" 21/2 thick with the wide point two inches forward. looks like it will be a rocket in good jersey surf, so i want some nice fins.
You may want to take a look at the Campbell Bros. 5 fin bonzers. Keep in mind that there’s a lot more going on with these boards than simply adding more fins. You can also try tapping Herb for some info on his superchargers.
