Inflatables are worrisome for me. What is your backup plan if you puncture it while moving your gear to and from the boat. A reliable BIB is not going to be cheap. I use a perception kayak that cost me $450 brand new. Fabricated my own rack and loading system and added some other goodies to my kayak. I also splurged on a good cart. I have less than $900 into the whole getup. Paddling a BIB a half mile is gonna soak some energy where a kayak will leave you with plenty to spare. SOTs are almost unsinkable. Piece of mind.
I have two OK kayaks and a 14 foot Novurania Cancura inflatable. The thought that inflatables puncture and go flat is in some ways silly. You would about as soon puncture my Hypalon Cancura as the tires on my Jeep. Yeah, it can be done but unlike a tire, real inflatables have multiple chambers. It is not a pool toy. I have owned it since about 1984 and ranged up to 20 miles off shore with it using engines from 10 to 35 horsepower. It is best with the old two stroke 25 horse Mercs and Yamahas. I caught a bull shark once fishing from it, he bit the sponson pretty hard, not even a mark. They are pretty tough boats, not toys.
My OK Scupper Pro TW is fine for journeys of several miles. It has a rudder system, portable radio, GPS, compass and is rigged for diving. I can carry a second tank in the front storage well.
I usually do not anchor the kayaks, I just tow them as if they were a a dive float, which they are. The inflatable is usually too heavy to tow but I have certainly drift dived with it and just rode along the current.
However, often I do not have access to my boats, so I just swim it having done more than a couple miles offshore swimming. It is a a long time in the water, tow an inner tube for flag and a resting place. Really an impractical distance but if it is the only way then it must be.
