The Why
There are valid reasons to always carry a hand pump when sea kayaking. In my home Canadian waters, a bailer of some sort is a legal requirement. If you’re assisting another paddler, a hand pump lets you empty the rescuee’s cockpit while leaving their sprayskirt fastened to keep out waves. It’s smart to have a manual back-up to electric devices. And I have successfully self-rescued using only a hand pump in moderate conditions. But when the surf really hits the fan, I don’t count on a hand pump alone to save my soggy ass.
