new antifoul and a bit of electrolysis found but nothing major. The good old shrimps are cleaning my hull? When I leave the shore power and anchor out it seems to disappear. Hmmmmm the age long debate that know one seems to come up with a dirrect awnser. I wonder if it's worse in a steel hull?
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 ?
On my trailer sailer there is no antifoul and no growth so nothing to attract or precious little for sealife to eat. So the amount of growth doesn't seem to be a factor. What I have noticed is the location does seem to affect the amount of clicking. Marina's not so much noise but pristine anchorages more so.
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.

Cisco.......time for you to move into the old folks home mate.
Try turning your depth sounded off!!!
Transducers tick with each sonar sent out, faster in shallow water.
When I got Felix 12 months ago she had 10 years of growth on her and no clicking sound. Since antifouling in June last year I can hear this clicking noise at night and I always wondered if it was the sound of sea life eating the anti-foul or something.
Nice to know for once I am not alone in my mystery.
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.
ok , time for the truth ........................................................................................................................................................................................................................................
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 .

I must have balsamites then
Yes, but they're easy to get rid of. Just pour some balsamit vinegar in your bilges.
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.
It's snapping shrimp. You can hear it here:
ocr.org/sounds/snapping-shrimp/
as water conducts sounds faster and more efficiently than air, plus the water surface acts as a reflector you can hear sounds from much further away - it really intensifies the sounds.

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.
