Everyone -

What's the commonest way of measuring wave height electronically (apart
from satellite) for the likes of ships, oil rigs and harbourmasters? A
friend of mine needs to measure wave height / sea height from the side
of a harbour and use the output (RS232 / RS485 over radio modem) to
control the lighting on the side of a building!

Names of suppliers would be much appreciated...

Google hasn't been my friend really with this so I'm posting here for
ideas.... any yachtsmen or merchant seamen in here?

Cheers - Les
