Low transoms and cockpit drains

I believe that statistics bear me out when it comes to boats sinking
due to waves over the transom. All you have to do is look at BOAT-US
statistics. It seems to happen a lot.
It's not simply an issue of having a "low transom". It's also how the boat
naturally drains water taken aboard.
Most small boats don't have scuppers. They have small diameter drains,
connected via hoses to an outlet somewhere at or below the water line on the
transom. I've been in some small CC's that, if one stands near the
transom, water will backfill into the boat. despite the silly little ball
check valves or rubber flappers that never work.
To me, taking a greenie or greenies into a boat from any direction, and then
having to empty the boat by relying on powering up enough to quickly remove
the water "over" the low transom is a recipe for eventual disaster. A
couple of heavy hits in a matter of 10 seconds or so can cause a serious
problem.
As for taking water on water "over" the low transom (which you then have
to get rid of before you take more and eventually swamp), I've seen cases
where, in rough conditions, water comes aboard faster than you can possibly
get rid of by powering up and hoping it runs out of the boat, over the
transom. The silly little drains aren't big enough to get the job done.
