TJ, without really knowing for sure, due to ignorance, I suspect that they are tubeless...they are 21" heavy duty whitewater pontoons, with fore and aft chambers that inflate separately, but they don't have any of the cheesy nylon covers or anything like that...just heavy inflatable material, blue.
How they are separated into two chambers, I don't know...but there doesn't seem to be any separate bladders and 'toon covers.
Repairs are continuing to move along...the big tear looks to be ironclad now, but like I said, the discovery of numerous little leaks is taking a while to firm up.
