If they are not deep V air matts, are standard flat ones, we are talking same language here, inflatable plank with inflatable keel under. One thing is pumping a tube to 10-12 psi, that will probably burst passing 5 psi. An air deck has millions of crissed crossed fibers, imagine an air filled waffer, holds pressures giving extreme rigidity any tube would't dare be inflated to.
Those mentioned high psi can be reached only if air deck is in perfect shape, that's with no blisters or sun punishment detereoration whatsoever.
Seago wants to be in the safe side providing 2.0 psi way to go, but with worst boat/engine performance. Seems they simply sell boats and not extensively test them on watrer for top performance advice. With low tube pressure and constant use expect engine & air deck rock & roll including transom damages in the short run...
BTW, just stating 10-12 psi for air deck, 3.0 psi for tubes and keel, not 10-12 for all. We offer long distance recovery and/or extended warranties, the only issue is that we are very, very far away, sorry :-)
