When stowing your gear in the boat, a few simple tips can make a lot of difference in the comfort and duration of your adventure. Here are a few quirky ones you may not of thought of.
Use the cockpit as a storage area.
The cockpit of the kayak is the largest place in the boat, both in beam and deck height. Attach some shockcord so that it runs vertically between the chine and gunwale bars. This will hold a large drybag against the frame and away from your legs.
Use some scrap fabrics to add labels to your drybags. This helps with in-camp organization and the repacking of your boat. Make a list of where certain bags went on your initial packing of the boat so that you can repeat this with ease in the feild.
Where at all possible, use many smaller drybags in stead of a single large one. Of course this is not always possible, but consider making 3 food bags where you would normally have one; the smaler bags are much easier to pack and will fit in the void spaces left by larger bags.
If there is an over-run of gear, you can always stash a bag or two on the deck of your boat (I always start a longer trip with a deck bag or two). The only thing to remember is that this bag must be doubled if you want it to stay dry at all!
Smaller bags and fuel bottles always find themselvs tucked away into the far ends of the kayak and if you dont feel like climbing into the boat after your bag, tie a rope to the bag. This will make it much easier, and graceful, to retrieve the bag.
