NASA clipper wind system

[A.d.orman]

Has anyone got a NASA clipper wind system and what's it like, I have an old Stowe wind vane not working so thinking about getting a NASA clipper wind

[dlymn]

The vane arm is too shot and means that the unit is often in the shade of the sails. The speed cups have jammed recently. Maybe salt is getting into it. Only 2 years use and tied off for overwintering. It has taught me that sail trim is a human skill and technology can help tell the story, "It was gusting to 32 knots from 137 degrees when all of a sudden..."

I have happily owned the wind and close haul display as well for 5 years. I cruise so I'm not as demanding as a racer would be. I notice that when docked I have no speed reading under about 3 or 4 knots of wind speed. When sailing I'm happy with the performance. I really like the low replacement cost of the masthead parts. I managed to break the wind cups and the cost was only about $20 Cdn.

The NMEA 0183 output works to OpenCPN as well.
