I do it to all my electronics (but don't live aboard...)

If you are skilled in electronics, or know someone who is, you can purchase
a product known as "Conformal coating", which is essentially liquid plastic.
You spray both sides of the PCBs, protecting certain components.

In 15 years I haven't had a failure, and some of that gear was old when I
got it.

abboard sailboats ?
