Re: what do you keel bolts look like?
Hey. Those aren't stainless steel bolts, are they? I was told that SS on an iron keel was a no-no.
Yep, they are electropolished S/S, coated with anti-seize before installation.
The pic of the rotten stuff I posted earlier shows what happens to regular steel bolts. I did a lot of research for that very reason - the conventional wisdom is no S/S in an iron keel. I discovered that the big Euro builders all use S/S in iron keels. Due to that and the fact they can be easily pulled and examined, I decided to go that way.
Also, I've never heard of an iron keel with S/S bolts falling off due to crevice corrosion, galvanics or anything else to do with the metals, just a lot of talk about how "dangerous" it was, none of it by the way from anyone who actually OWNED an iron keel.
However I HAVE heard of iron keels mounted with steel bolts falling off - one of them was another Columbia 43 in Sausalito.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
