WTF? Assuming this to be true, and I doubt that it's misprint,

I'd love to hear the builders rational behind this design.
Anybody know the voltage on the Pacer backup pump? Can't seem to find it on the Pacer web site.
But either way AC or DC powered, specing only 4 11 GPM pumps (which are rated at open flow by the way so even that number is meaningless) is pitiful.
If I was the company insuring a vessel with that bilge system on it I think I'd demand it be manned 24/7.
