My Stealth leaked through the hatches when I first bought it and was a little worrying so I put pool noodles inside for peace of mind. I used enough noodles to support the yak, myself, and my gear. I have them front to back so the yak will float level, and near the top so the yak won't want to flip over. 300lbs (10 noodles) of buoyancy probably won't keep me out of the water in case of a total flood but it will keep me and the yak on the surface for sure.
