Hummer Wind Sensor – Real Installation on a Steel Sailboat

Earlier this season, a Hummer Black Anemometer with mMFD was installed aboard Tupac Amaru, a 36-foot steel sailing vessel, currently preparing to continue sailing in the South Atlantic.
Tupac Amaru is not a showroom boat. It is a working, continuously evolving vessel, refitted and maintained while navigating long distances and exposed to real offshore conditions. This made it an ideal platform for a transparent, real-world installation and evaluation of the Hummer wind monitoring system.

A Real Installation

The crew documented the entire installation process in a detailed video: from receiving the equipment and planning the mast-top setup, to routing cables, mounting the sensor and electronics, and finally integrating the data into the boat’s existing electronics stack.
The system was integrated using Signal K, NMEA 2000 and a Raspberry Pi, reflecting a setup commonly found on owner-maintained sailing vessels.
There were no idealized steps, and no “clean” studio conditions. The video shows real decisions, adjustments, and constraints that arise when installing equipment on a boat that is actively sailed and lived aboard.

Honest Review, Not a Commercial Demo

This was not a commercial review or a scripted tutorial. The goal was to provide an honest look at how the Hummer system behaves during installation and early operation, highlighting both strengths and considerations that matter to sailors planning a similar setup.

Ready for the South Atlantic

With the installation completed, Tupac Amaru is now equipped with a reliable wind monitoring system and is preparing to continue sailing with its crew through the South Atlantic.
