FO do great Board bags for SUP, but they don't do a 12'6" BOP race board shaped bag to the best of my knowledge. They do have a 12'6" bag in regular SUP shape.
i picked up a starboard one fits the 12'6' hobie very sloppily can also fitt the psh 10'11' gun in tip to tail when rigged up as a quad, only probs is lifting the two onto the roof rack ,has full zipper all the way way around would be good for those who want to fit there race board and surf style in one bag,just lay some towls beween boards to stop skratches and remove large ceter fin on surf style board,ive cut a slot in bottom so race board fin can come through,just need to get it down the canvas shop to sew some edging on to prevent freying, price was rite ..
and if i die i think i will tell the missus she can use it as a coffin for me just lay some cheep ply in the base to keep it stiff, i will be happy with a few lads carrying me in that
