With all the gimmick's out there ,you would think somebody would of come up with a box fin.
All I read about is pop this ,and pop that ,pop1,pop2,pop3 pop4 ,snap, crackle & pop,and my favorite pop go's DA weasel
If your board DOES NOT have a box fin your losing POP or I like to call it "BLAST"
If fin is put on by screws your fin is has to be TOO WIDE ,And a fin that is TOO WIDE,creates CAVITATION which creates LESS POP or I like to call it "BLAST"
Now a box fin is 1/2 the thickness of screw-on fin ,which allows your board to sit DEEPER in the water. So your board can cut though the water "like a hot knife cutting though butter" that creates MORE "BLAST" OFF THE WAKE
That's are opinion... What's your
