Replacement for Autohelm ST50 wind indicator
After my ST50 wind indicator sadly gave up the ghost after 30 years, I needed a replacement!
The design matches my still-functioning ST50 Tridata. Installation was relatively straightforward, although the existing hole had to be significantly enlarged. Even though the existing cable from the old unit could have been used in the mast, I replaced it with the included cable. Cables do age, after all. For the necessary deck separation, I used a slim, waterproof 5-pin connector from the automotive sector (available online for a song (€7)).
It remains to be seen how long the plastic mast mount will last. The previous one for the ST50 was aluminum. All the parts seem to be of high quality.
The price, however, is typical of Raymarine.
