Re: inflatables
The 'airdeck' is not an option you can buy. It is made with the boat. I have a Zodiac Fastroller 310; it has an air floor. Think of a 1" thick inflateable floor (7 lbs of pressure) similiar to a wood floor. It is a special design and actually has 1" cords holding one side to the other creating the 1" thickness...quite sophisticated, actually. You blow it up vs unrolling a wood/aluminum floor. There lighter and more comfortable to sit on. The whole boat less motor weighs 65#, and fits in a bag.
