I'm building a SUP to a old mate 5ears experience SUPer used to ride longboard with some classic board from California as Hobie, Martinson, toes on nose series and other ones of that kind. So i keep in mind these 9' longboard premodern shape and designed this SUP for him to spend (our) winter in Sri Lankan waves:
i will put some picture of the board later on when it will come out from glassing job which i hope light to under 7kg finished board.
