I have a brand new Precision Pak Yakmate1 for sale. It fits right in your tank well of most kayaks. This thing holds a lot of gear. Actually a lot more than I bring with me which is somewhat why I never used it. I have the two original plastic tackle boxes that fit inside and a small one that fits an outside pocket. It has two rod holders and a Boga style scale pouch. The only thing I don't have is the soft sided cooler that is mentioned in this ad. I don't think mine came with one.

If you click on more images, you'll see the inside. It's a very nice bag, just a lot bigger than I want (just a personal preference).
I'm asking $50 for this new bag. Can be picked up in Rockland or somewhere within reasonable distance.
