I have not checked yet how much water stays in the cockpit after a rescue,
how it works while sitting in cold water (I used WARM water in the bathtub
and got only my hands wet) and didn't check how long I can keep pumping
without passing out. Valid questions, but I can't answer them from the
bathtub test. I am going to build the pump and perform the next test in a
swimming pool, after that I can tell you more.

One question I can answer: This pump is meant as the MAIN pump in my boat. I
will carry a handpump as a backup.
