But for those of us who are into wilderness camping away from the madding crowd, the kayak affords this to be done in style, complete with table cloth and stemware if that is your desire. Unless you plan to portage your kayak some distance, weight is not too much of a concern when preparing your camping list. Volume and durability should be a factor though. For example, I would choose bagels over a loaf of bread as bagels take up less room and don't get squished as easily when packed tightly in a hatch. Most single sea kayaks will hold an incredible volume of camping gear.
Some doubles can carry a phenomenal load.
It was an awesome sight to see how much eight of us loaded into the boats for our Gulf Island tour two years ago. Actually, it was disgusting that we took so much for five days, but we weren't lacking for anything and it did all fit. Ideally you should look after life's necessities such as food, clothing and shelter, after that you add niceties like toilet paper and finally luxuries. I strongly recommend that you create a camping list of everything you might want to take and use the list as a checklist for future trips. You will probably modify it a half dozen times, but eventually you will have a perfect quick packing list for your needs and wants.
