Heyy Old Boy.
I have a custom made board, it is 138 x 38 cm..wanting to sell it so if your interested check it out in the buy and sell section on this forum.. I'm not asking a lot for it, just wanna get rid of it because I don't use it anymore.. I don't get to the beach much these days..

The previous owner weighed around 110kg and he used it as his primary kiteboard. It has no fins so you'll be able to get up in fairly light wind.. Pretty much everyone that kites here at Yeppoon has used this board or another the same at some point and all agree its an all round good board, can pretty much use it in all conditions.. we have quite a lot of chop here as well so it will probably suit your conditions well..
Let me know if you wanna know anything else..
