[Public-List] Garboard drains

[Mike Lehman]

Well hull #123 (built 1965) is at the boat yard down the street from me and
we had to drill a garboard drain in the boat because, even on land, it was
filling up with water. Using a magnet we could NOT find where the ballast
ended, So we went to another A30 in the yard #655 (Built in 1981) to use
the magnet because it has iron ballast and measured up from the bottom of
the keel to the magnet line, then transferred the measurement to #123 and
drilled a hole...which was right at the top of the ballast. #123 has lead
ballast....so it was more than a few boats with lead. I understand that, in
the US lead, was banned in 1978 especially in paints and gasoline and
perhaps in ballast. I don't when Whitby stopped using lead and I am sorry
that I cannot remember what the measurement was, but later today I will
walk down to the marina and measure where the hole is.
