We took the boat with us in our normal luggage on the plane for our houseboat holiday north of Berlin. I have to measure the size and weight tonight.

Don't know exactly what you mean by "air chambers" and I only used the boat once lol, but if I remember correctly, there are 3 pipes/areas to inflate. With a quick Google/Amazon search, I found the same description, so should be right. http://bit.ly/2Lksxgb
