Last time the boat was hauled I noticed that about a half metre down the keel
there were some blisters
with some water
in them. They were leaching a green coloured water
substance sort of like brass corrosion
are the same distance apart that the keel bolts
The top of the keel bolts
inside the boat are fine. No corrosion
, dry and no sign of any problems.
is a fin keel and I draw about 1.8m. It is glass for maybe a foot and then the lead starts.
I have a few questions:
When the keel is formed do the bottom of the keel bolt shafts get put into the molten lead?
If not, how are they attached at the bottom to the lead?
Next time the boat is out should I take the grinder to the side of the keel and start exploring to see what is going on? I can easy epoxy
it all back up. After it is expoxied I can sand and antifoul it and it would look no worse for wear.
What do you reckon is going on? It has actually been doing this for four years now and probably a lot longer for the previous owner.
