That's the most helpful descriptive analysis I've seen on this forum. Just need a comparison chart with all the brands and their sharps naish, starboard etc and board selection is done.
The simple answer to that is that the guys from BP Australia probably took the photo and the guys from BP Hawaii liked it so they decided to use it.
It is a great summary.
But I have to confess there was one statement that caught me by surprise:
"In general, the fuller the outline of the board, the more stable the board will be and the better it will be for cruising in calm conditions, whereas the more pointed the outline is, the more control and displacement the board will offer, making it ideal for windier or choppier conditions."
I would have though that if it was choppy I would want a board with more width in the nose and tail because it is more stable. Is he saying that a pointier board is less affected by waves? I guess I can imagine a 14' pointy board piercing the waves instead of bouncing over the top, but is that true for a surf board too (that does not have the same 'hull' shape as a racing board)?
