Ask HN: Arduino to measure height above water?
Can you think of a good way to make this:

using an Arduino, but not using accelerometers.

GPS would be an alternative, but pricier and probably less reliable. There are of course a variety of ways to measure height above water like ultrasonic or radar sensors but good luck water sealing them and keeping them oriented downward in this application.
They also mis-read jumps.
Just wondered if there was a different way of measuring height.
[edit] Boards fall off feet, then get washed around in the surf. This seems to fool the sensors quite a lot.
