Technically, it was a large machine screw.
There I was, scraping bottom paint, and a huge chunk of paint comes off and along with it, the screw head falls out of a thru-hull.
When we first started cruising, Dave and I would have greeted that with dismay – what now? (Some days, I still think that Murphy — ‘anything that can go wrong will” – was an optimist.)
Now, we both had the same reaction: glad it happened now.
I mean, if a thru-hull bolt is going to break, the best place to discover it is when you’re already hauled out and in a boat yard. We’re in the perfect place to fix it (and replace the others in the same fitting and check those on the rest of the boat).We’d much rather take care of things when it’s not a critical time. When it’s a maintenance task and not a emergency situation.
For those interested, the other machine screws in the same fitting appear just fine although we’re going to replace them just to be on the safe side. Looks like the one was buried in sealant and crevice corrosion got to it right where the head meets the shaft.
