[quote=MN3]12 is not to much air but that is defenatly alot of weight (probably more than that boat is designed for).
12mph isn't all that big but every 7mph (or close) is a 10x increase of stress on your rig...
I am fairly certain your cat can handle the weight, but if you have stress cracks, or gear that is ready to fail.. it could be the "straw that breaks the nacra's back".
Again, you should be ok.. just make sure to have emergancy gear ready (pfd's, cel phone, paddles, rum, cute nurses.. etc.) perhaps stay closer to shore than normal? [/quote]
