Alan,

 this one again as I didn't recieve it.Hank,glad you posted, I thought I wasn't getting any
 mail.From memory G.L. require a bilge pump with an
 ability to pump outall spaces in the sub.I
 don't think they require high pressure pumps for
 pumping out at depth as they talk about allowing an interconectability
 between the bilge pump &trim tank system. So this implies you can have one
 pump for the trim tanks & a
 valve system from it to pump out the
 bilge.I
 would guess you would need a one way valve & a stop
 valve on the through hull.If you had large enough trim tanks you could use
 them as a ballast tank as well.Alan

 Are bilge pumps common or required by ABS, if
 so are they high pressure or low pressure for the surface
 only.
