Ok what's with the clicking noise you can hear from inside your hull in various places in harbours and marinas?? My conclusion is that it is electrolysis as it seems louder when I'm near steel boats. Some say its prawns or shrimps clicking on the hull, any thoughts? Answers?
Snapping shrimp is the term. Its small shrimp with claws that they snap shut that they use for communication. Sound travels easier and 5 times faster in water and passes through steel boats easier than most.
As long as it was dead then surely no more damage could be done 
Damn Irish ...... they'll eat anything
Guinness is black death, it could be used as an anti fouling except the EPA would probably ban it as a hazardous substance.
I'm off to Ireland in June for a month. Guiness from the factory in Dublin is on the todo list.
Scotland for another month, Scotch time.
A month then in England for some local bitters.
Don't know what the missues will be doing!
The clicking under the boat, very common in Broken Bay, snapping shrimp as Ramona said.
Aren't you lucky, just clicking noise.
I remember, sledgehammer whole night.
2000 tons cargo ship on anchor and icy pieces in the river current.
or -15 you touch anything on the boat, you rip off you skin.
/your finger instantly freeze to the metal/
Get under the house will ya?
