The Cargo Fly is an airtight, waterproof zipper system in the stern of the boat. Opening this zipper allows access to the inside of the tubes to store your gear. With careful planning, everything can now go inside your raft rather than strapped on the bow in a pack.
The Cargo Fly option comes as a three piece set. The set includes the zipper in the boat and two zipper opening inflatable drybags that slide inside the boat tubes. These drybags are long and a slightly smaller diameter than the boat tubes themselves. After the drybags are slipped inside the tubes, they are filled with gear and clipped in place. Once in place they are inflated. This gives you two additional air chambers.
We use the Tizip Superseal zipper for the zipper in the raft opening. This zipper has a long proven track record for holding air and staying dry in multiple adverse conditions.
Some special considerations are necessary when using the zipper. Constant vigilance to keep sand out of the zipper is important. The opening is limited in size, so everything going in the boat needs to be in containers that are “long and skinny”. Care is also needed not stress the zipper during loading and unloading.
We can retro this option on all boats that have the “big butt” sterns, which started with the 2010 models. Unfortunately, older boats with the small sterns don’t have enough room for us to get the zipper in.
