Oh, so I went and here's the answer. There are two kinds of cooler tubes. Blue and yellow. Blue is smaller than yellow and is cozy for the taller roll behind like carryon luggage type coolers. The yellow one easily fit my bigger cooler which was about 27 inches wide and 15 or so inches deep. Happy float. And note that size does matter. It may not be an all day float (but 6 hours is a long time) we had a big crew with lots of people and kids who need snacks and things, so a big crew needs a big cooler. Cheers!
No it will need to be a smaller cooler. Probably no more than 18 inches w x 12 inches deep. Height is not usually a problem
Small only!
We had a 28qt Igloo.
Yes a smaller cooler is best after all, it is not all day float!!!
