As long as we are talking about kayaks floating away here's a thought. Not happy with the amount of positive flotation in your kayak, and want to improve its' safety if you ever get swamped?
Walmart sells these 15" diameter beach balls in different colors for just $2.50 each. Surprisingly, the two I placed into my kayak over 12 months ago continue to maintain a good airtight seal and remain fully inflated. To increase your kayak's buoyancy, place one beach ball into both ends of the kayak after deflating them, and then reinflate so they will fit tightly within the pointy ends at the bow and stern. The vinyl surface of the beach balls should have enough friction to grip the inside kayak surface without sliding around.
You just improved the buoyancy by a whole lot which can be a big help if you ever need to cling to a swamped kayak in some big waves or something while praying the Coast Guard J-Hawk helicopter will see you.
