If you are going on a months-long tour up the Inside Passage you might want to carry a lot of supplies. This is the kayak to do it. It has the capacity to carry a large load efficiently. It is stable enough to be rigged with a small sail.
This boat may not be appropriate if you feel you just need a little bit more capacity than normal, it is best suited for situations where you need a total capacity over 350 lbs. and will still perform well with over 600 lbs on board.
If you're a big paddler, you will find this design efficient and comfortable while still able to carry a lot of gear.
