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

The board didn't work as a quad, but does now as a 2+ 1?

it looks great

Good try out today definitely adds another dimension to the board - some great pics from Lano

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
