No cure, but it can be controlled by frequent applications of okoume, fiberglass, epoxy and varnish. Just sent Dr. John and his gang of med students a check and they'll put together a prescription for you.

kayak will outrun a SUP  allways.

I guess that means I will have to build 2 SUP's.  I think it would be poor form to leave my wife in my wake.

So much for a cure.  More like a fix.

The SUP will lose every time and fail miserably in any kind if a headwind. The SUP is siccessful in the unique even natural posture standing offers but its an awful craft when its efficiency is measured against a sea kayak - particularly when conditions get challenging.

I paddle a Shearwater 14 and my husband paddles a displacement racing SUP.   I am faster than he is in no wind conditions and much faster in a headwind, but he keeps up well downwind.  If it's a really strong downwinder he wins (no of course it's not a race). Note that the common surfboard-style SUPs are much slower than his SUP. 

I am working on a Kaholo 14 for him (things are going slower than planned - work/life keeps getting in the way) and we'll see how that does.  We average 3-3.5 mph on most of our paddles depending on how many breaks we take and conditions.  If I'm paddling with other fast kayaks I usually average 3.5-4+ mph.  If we're going out recreationally with friends in slow kayaks it's 2.5-3 mph.

I think you'll just have to build 2 SUP's!
