Hi all,
I have fixed this one for a while - I used the 2 big washers
approach, and its completely watertight. - I'm not sure what to do
long term - comment about getting it surveyed asap is what I would
normally do, but it was surveyed 6 weeks ago, and passed with flying
colours (min 5.5mm of steel). Makes you wonder why I paid for the
survey. I'm going to remain watchful - even if another hole like this
opens up I have a day or 2 to spot it and fix it, and given I work on
the boat most days, I don't think it'll sink too fast.
It also makes me think I need to seal up some ribs (so that the
water will fill up one section of the boat good and deep, so be easier
to detect/pump should it happen again), and put in some detection
system. does anyone else have anything like this?

cheers

When you think about it the two washers and bolt idea is perfectly
sound. I have a "ground plate" bolted to the side of my fiberglass
boat using exactly the same technique.

When they did your "survey" did they take thickness readings of the
hull? On a steel boat they should have done and furnished you with a
drawing of the boat with the places where testing was done noted.

you could certainly start epoxy coating or epoxy/fiberglass cloth
coating the hull, either from the semi dry bilge or even outside
(in the water) the hull with common 'apply underwater' epoxies. -
although cathodic (electrical charge) issues - known or unknown -
are a possibility and will prevent underwater bonding.

In the chemical industry - pitted pipelines etc. are common
wrapped in epoxy and fiberglass cloth wraps - to reinforce the
piping and restore pipe thickness...
