I found the problem with the dry bag. Small little tear at the seam unnoticed before I set out. I filled it up with water to find the leak and even then it was hard to spot. The problem with the sit on type of kayak is everything on deck sits in about 4 inches of water all the time.

Good idea on the desicant packs. It would help were condensation occurs for sure. I wonder if you can buy those in bulk ?
