There is one user group even more dependent on reliable engine

So it's no accident that a pre flight walk round includes a fuel
sample (off the bottom of all tanks, and at the prefilter) to dump all
water trapped in the fuel.

A sampler valve might be a good idea for boaters too??

I would second that. My previous boat had an aluminum tank that was
odd shaped with one corner sticking down. That corner collected about
a few ozs of water which eventually corroded through the tank. A
drain would have saved a nasty repair. In fact, I think it would be
hard to find a shop willing to do such a repair nowadays.

I mention quick drains from time to time. You can buy them in several
screw threads.[Use Aviation Trader] Activated by a pin and sampler
cup, or by a push n twist fitting. They use double valves for
security.

But I have heard it said that a tank drain may be a no-no in some boat
reg versions.
