Also would like an answer to this! The voyageur sounds like (and looks like from pictures) two people couldn’t sit comfortable in it as it stands.
I also had a question (maybe even you could answer joe). Buying extra material to lengthen this. If I want to lengthen it by 3 feet, would I then need 6 ft of the 210D material that’s sold, or is it wide enough that I just need 3 ft and there will be enough for both sides for the tubing?
