But there are other things like lighting changes that we are thinking through. Like putting a tri light on each mast of the schooner rigged boat, and turning the forward one on and the aft off. Also need to switch the side lights.
Some have suggested it might be easier to flip a switch to inform all the systems of the new direction.
Perhaps it might not be needed if we can get smart enough software.

Can the davis 7 be set up to report wirelessly?
Have you done any work with, or know who has done work with, ultrasonic water speed/direction sensors?

These parts are common enough in the automotive domain. Would be neat to hack together a cheap alternative.
Water speed, direction and temperature in one hard to clog sensor.
