[Public-List] Garboard drains

[Mike Lehman]

The older boats had lead ballast. I believe it was the late 60s or early
70s when Whitby switched the iron, due to health concerns for employees
with lead poisoning.  If you have a boat with iron ballast, using a magnet
works to find the top of the ballast.
