With a Chinook 8" fin box from Mark Taylor at Surf Sail Australia and the wealth of fibreglass skills of Mark Taylor Board Repairs in SA you end up with a very tidy large wave Quad Thruster (101) that works really well. The 20cm thruster and Stubby 12cm sides work - roll on winter swell - really for those cross off 10-30knt days where you need the float and the rocker has a calming effect on the gusts and it stomps up wind (compared to quad)
An experiment that's actually worked
Worth keeping, they are a good tough board with the wood and carbon/innegra deck
I'm currently refurbishing an 81L a couple of years newer than that, just tiny rail dings and to be sold off. FYI of Fanatic quad fans.....
I might say the quad fins, could have been improved on, while not just bigger, but I will think it instead.
Did you try it as. Twin ? Twins not my cuppa but maybe yours.
i like what you did.
No didn't try it as twin - but love my Kode 2016 wave 83 as a twinser - had a JP twin many years ago and wasn't a fan
