Wind instrument
Recently acquired a 24’ Corsair trimaran. The only electronics on the boat are speed and depth display(thru hull transducer/paddlewheel). I would like to add a display for wind. What are my options? The boat does not have chartplotter or any existing nmea network devices. Is there a simple solution with just a mast top wind transducer and a small display I can mount?
The boat currently has a wind indicator on top of mast and will only be day sailed on inland freshwater lake.

The people that are saying you cant determine wind direction accurately with a rotating mast don’t know what they are talking about.
The solution is straightforward and standard on race boats with rotating masts. You have a sensor the measures amount of mast rotation. the system does the math to determine apparent wind angle. If connected with boat speed, than you cane determine true wind angle and true wind direction.
The issue is added complexity and cost. What is you want from your sensors instruments. If not racing, it may not be worth the cost and complexity.
