Why are the 737's rear doors unusable in a water landing?
$begingroup$
The 737's rear exit doors cannot be used to evacuate the aircraft in the event of a water landing, as shown, for example, in this safety card:
(Image from flight-report, via Jordy here at AvSE.)
In contrast, the rear doors on (for instance) the A320 series can be used for a water evacuation:
(Image by Czechnology here at AvSE.)
Why can't the 737's rear doors be used during a water landing?

I like the optimism of these "safety cards" showing a pristine aircraft floating nicely on the water after a ditching. Statistically unlikely but makes for a pleasant looking card.

The bottom of the door opening sits too close to, or below, the water line when the airplane is floating.

Why would that be a problem for the 737 specifically, rather than for small-to-medium narrowbodies in general?

I think most airliners sit tail low when floating so it would just depend on the rear door configuration from airplane to airplane.

It all goes back to how the aircraft is designed; the ways different planes float vary.
when the 737 ditches on water the tail-section of the plane is deeper in the water than front of it, because the wings are a huge floating point and support most of the weight of the aircraft when afloat, and the bigger front of the airplane contains more air so when floating it will be lighter hence pitching the nose up, causing the tail and the rear doors to be below or very close to the water. this is why these doors remain shut in the event of evacuating after an emergency water landing so that water doesn't get in any faster, giving the plane and its passengers and the crew more time to evacuate and stay afloat longer until help arrives.
