I saw this post on Facebook and dismissed it at first as you don't need tools, it's a kayak, and then I started thinking. I do actually keep tools in my boat and have needed them on numerous occasions.
For me it's a screwdriver with bits for everything on the boat and a Leatherman. I can't tell you how many times I have had to tighten a hatch or fix a seat. Aside from that I always carry zip ties and nylon webbed strapping because I have been caught without them before and it was no fun. How about you? What have you found you need to bring with you as far as tools or repair materials? It's something you never think about until it's too late.
Here is a good link that will give you plenty of insight of needs while on the water.
