T&T: ART Roll reduction

[Ron Rogers]

Dave,

Your mention of "heel" made me think of a possible reason why they don't. At
a Safety At Sea seminar in Annapolis we were shown a USCG film of a fishing
trawler in the Bering Sea. She had taken on water and lost power. She was
heeling to port when a wave lifted her starboard side. At that moment,
something happened and she kept going to port and turned turtle.

The board of investigation found that she had "saddle tanks" with an
unrestricted pipe connection. Since her tanks were down, the starboard tank
contents flowed into the port tank and over she went.

Can you explain how the ART is different than this example? I'm sure that it
is.

Thank you,
Ron Rogers

I still don't understand why more naval architects don't use this method.
Maybe its some Kool-aid thing or that it flies in the face of
expense/maintenance/etc. I just don't know.
