We have just recently moved onboard our 36ft steel cutter
, for the past two years she has been sitting on a mooring
, for the 20 years prior to that she was sailing around the world in the hands of a very capable couple who owned her from new.
My question is this. I have noticed that when it is very quiet I can hear a constant crackling type sound. This has me extremely worried as I'm terrified of corrosion
, stray currents, electrolysis
etc (mostly because I don't understand it or know much about it). My previous boats have all been wood, I have never heard this crackling sound.
To be honest it has always been there, I remember quiet evenings on the mooring
wondering what it was. I've disconnected all the batteries and the sound persists. I'm hoping someone is going to tell me all metal boats make this sound and its just the annodes doing their job? A racer
next-door on an all carbon fibre job tried to convince me of this, I'm hoping someone out there can confirm this?
If not, if it is the dreaded electrolysis
or some other such problem what do I do? Metal boats are a whole new ball game
Any help much appreciated, I may even get a good night sleep! Its a bit of a worry.
