This could be the breakthrough in iSUP construction that we've been waiting for. A bit heavy though, and what about price point? What attracts a lot of purchasers to iSUPs is the lower cost than hard boards.
Will be interesting to see what the race board looks like. An inflatable downwind board with good performance and that won't sink if holed would be a wonderful invention.
.. except it might be like standing on a corrugated iron roof..
