Yeah it could & can be ordered. Its basically an ECO alternative to the typical E glass used in most surfboards. I'm surprised Rasta's not building hemp fibre surfboards, he could source his materials locally

"Flax Fibre ClothFlax fibre cloth is an engineered reinforcement fabric made from the bast of the flax seed plant. While flax fibre is one of the oldest cultivated fibres for textiles, it is only recently that its use as a fibreglass substitute has been acheived. Incorporate flax fibre cloth in your next custom board to add a great earthy look and to lower your carbon footprint"

If your chasing something really strong, Lib Tech has a new board shape more like a traditional LB. Only 7'6, but would be heaps fun
