New anodes and new paint, makes it more so, but the saltier the water the more static is audible and when its phosphorescent enough to see your anchor chain glowing into the depths the static is very noticeable.
Can't say about shore power because well, I've never tried it. So rule that out ?
In a steely at its cracklyist, it's not as loud as rain on the deck. Ferros also do it.
And wood ?
My guess, it's the anodes doin the thing and the hull is like the sound box of a guitar ?
More questions than answers ?

The clicking sounds are from a particular breed of marine worm that thrives on fibreglass.

Each time they bite a chunk of fibreglass off it goes click.

It is like a countdown watch with each click representing one second less life left in the hull of your boat.

There is a special anti fouling paint that has other worms in it that eat the fibreglass chewing worms and each time they have a poo, the poo replaces the fibreglass that the fibreglass eating worms have chewed off.

I don't know where you buy it though. Every chandlery and paint shop I have been to asking about it say they do not know what I am talking about.

Quite mystical really.

Maybe Van Morrison knows where to get it.

Try turning your depth sounded off!!!
Transducers tick with each sonar sent out, faster in shallow water.

Cisco's got it right. They are called polyestermites. However, the sound of the polyestermite eating away at the polyester resin of fibreglass boats can also be mistaken for the sound of the strands of 'glass snapping - after all, glass is very stiff and doesn't like being woven so it eventually breaks. If you don't believe me, try weaving some windows together.

Fibreglass boats are inherently doomed. The only saviour is wooden planking or balsa core, because polyestemites hate wood and stay well away from it.

It's sealife.
Hear it diving all the time if you pay attention. Some places more than others.

its the birds walking around on the deck of the boat while you are resting inside . they are just looking for a a nice place to crap .

They found it, my sail cover!!

And all this time I thought it was my brain stripping a gear. So glad I can fix it with Vegimite. Or was that Balsamite? Now I am really confused.

Yep that's the answer! I have heard it while diving, must be on the pontoons in the Marina cause I slept on anchor last night with fresh antifoul and couldn't here anything.
