Again, look at the extreme. A 22" wide straight rail 12'6" race board is incredibly tippy, and surfs like a telephone pole.

So the question is does tippiness = speed (performance) on a race board? Time to review those marine engineering equations perhaps?

Softball question but a very long answer. But yes. Mostly because the board length restrictions are so dumb, but yes. Nine to one (l/w) is a "magic" number for starting to ignore wave drag. Get your 12'6" down to 16 inches at the waterline and you'll really have something. Of course you need to weigh 80 pounds and have the balance skills of a squirrel, but yes.

yes but is there a situation where you get great performance without undue tippiness or in other words  great performance and greta stability combined.  It seems that the closest to this is   the simmons style boards and similar shapes like the hammer?  so  a goal for  shapers would be  to generate  a shape that is extremely stable and  yet  performs verywell. so  tweak bottoms  fin locations concaves  and all other aspects of  the board to get the most out of it.  shapers  game  On!!!
