[C320-list] Knotmeter knot working

[LaChance,Michael B]

According to products listed http://www.maretron.com/ there is no
ultrasonic speed transducer but there is an ultrasonic wind transducer.

I would be interested in a paddle-less transducer that would interface
to Raymarine instruments if anyone knows of one.
