Oh well here I go again. Wrote a post but off it went into cyberspace. Lol!!
Finally got a nice swell at about 4ft plus to try out my fin system on my 7ft Coreban Hyper.

Those who know the Hyper. it has excessive rocker & is very slow to paddle & late drops are the only way to catch waves.

I changed from a thruster to a quad with nubster hoping it will speed up the board a bit. But the exact opposite occurred. Why?

I found out it was the fins cant or angle towards the nose plus area of fin surface pushing water when paddling & surfing in a straight line. Why board shapers make side bite fins pointing towards the nose on excessive rocker boards I am not sure. Yes I know those that work a board hard will eventually get ultimate speed I think?

Anyway, I took all fins off & replaced the centre whistleing fin with an old 1980's centre box fin. I think similar to a 7 inch dolphin type that I took off an old surfboard.

The result was better speed but less control making me spin out easily. Best way was to surf with slow carving manouvers. But I am a cruiser not a bruiser type of surfer. So maybe a bruiser could rip on this as a thruster or quad. My mate is more of a bruiser & loves this turn on a dime board. But compared to my 8ft 3" Sunova Soul it bogs down at the base of a wave & is hard to paddle to gain any speed.

So I then got two nubster fins from Wet Fins & installed them as side bites.
The result was better control & with the better original speed for my style of surfing.
So now looking forward to mastering this board that will make me improve on working a board for better performance.
In my opinion for a slow paddling board, take off all fins except the centre on a thruster & try smaller fins on a quad set up.
My next will be a twin fin with nubsters forward or rear on my Hyper.
But at the moment happy with the speed & performance for this 7ft board that can take an excessive nose dive without digging in! Lol!
