Re: Centerboard Cable thru hull question.


 

I don't actually know if my hanging-on-by-a-thread thru-hulls where 3M
4200/5200, but Daniel probably doesn't know either. If the boat has
been out of water for a long time, that's a lot of time (probably)
polysulphide has been seeing 80-90F temps instead of much cooler water
temps. "Your Mileage May Vary" goes back to at least 1991 Usenet and
still seems to hold. Up to Daniel to decide what he's concerned about
and what he isn't, but there's wisdom in dealing with things while
you're on the hard that you are concerned about instead of suddenly
deciding later that you should have, and this is a fairly easy thing.
It's definitely true that most things are probably fine. I've jumped
on and sailed with new sailors who just bought a boat, and had no idea
what shape she was in. Usually the brand new skipper is a much larger
liability than the boat, no matter how gnarled the boat. So, tl;dr,
this is an opportunity to deal that now if you might later decide you
should have done it now. I definitely often take solace in the
thought that "well, she's survived this long, this is probably ok",
especially when waves are breaking over the deck and the rigging is
whistling.

Cheers,

Certainly, fair points. ?And we ARE talking about holes in the bottom of the

raised, that of things specifically bedded in 4200/5200. ? My experience may
be different from others, but I have been unable to separate 5200 bonds I
know I made in the early 1980s, when they were more than 30 years old.
YMMV.

As to the 4200/5200 comments, I¡¯d say first, how would you know? ? Or at
least, how would you know without trying to remove them?? I¡¯m personally
unaware of there being a longevity problem with either of those two
products.


I think the point is to rebed anything that would typically be bedded with a
compound like 4200. It doesn't matter what was actually used -- only that
you do not know when it was last done or how good of a job they did. Those
products do last a long time, but not forever, and there are not that many
things to rebed. So, you might as well do it and then not have to worry
about it for another decade.
