Improvements are disclosed here for a sailboat wind sensor (PCT/CA2014/000416) in which the solar panels form the tail of the wind direction arrow, and a digital compass is built into the wind direction arrow. The battery is moved to the nose cone and held in waterproof container to serve as a counter-weight, eliminating the brass nose cone which is traditionally used on anemometers to substantially reduce the weight. A new method of encapsulating the electronics in the tail is disclosed, using ultrasonic welding of a shell over the circuit board, rather than molding a resin over the electronics.
