Re: [PSUBS-MAILIST] Main ballast.

["Dan H." <JMachine@adelphia.net>]

Pierre,

On the K-350 the "hard ballast tank" is located under the hull.  There is a
shaft that runs through the hull with a flex coupling on it that is directly
above a quarter turn valve on the sea water opening of the hard ballast
tank.  A quarter turn of this threw hull shaft turns the ball valve
directly.

The "soft ballast tanks" are of fiberglass and are located fore and aft.
They are opened to sea water all the time.  The vent air is controlled with
quarter turn ball valves located on the conning tower.  The valves are also
located external but are altered with special long stems so they are
controlled from inside the conning tower.  The valves are connected to the
top of the tanks with tubing.  The valves are mounted high in the tower and
vent from the tops of the tanks.

Hope this is what your looking for.
Dan H.
