Justin, whatever that "Extractor" is I think they have been breathing bad air!!!
Fishandchips, I have owned several inflatibles. They can roll up in a van, can launch right from the beach. Mine have landing gear which attach to the transom and flip up and down. Easier to launch than you might think and my Novurania will run 40 plus MPH with a 35 on her. It takes two people about 40 minutes to rig it out or do what I eventually did which was keep it partially inflated and assembled on a small trailer. Once to the beach, flip the landing gear down, finish rigging the boat, pull the boat of the trailer and load it with gear and then roll it on the landing gear right into the water. Inflatables and kayaks have much the same benefits, freedom from long surface swims, increased range and access to dive sites, increased safety, speed, flexibility. Rigging them out is surprisingly similar and the way they are used to. I tow my Novurania just the same way I do my yak. The Whaler must be anchored or leave someone on board to tend it, it is simply to large to tow (by a diver).
You can make a suitable launching cradle for your yak from pvc pipe and wheelbarrow ballon tires. I have not tried it but I think I could build a yak trailer I could tow short distances with my mountain bike!!!! but loaded with all the scuba gear I am not sure. Nemrod
