Rick,
If I am reading this schematic correctly, those are solenoid controlled flood ports and vents for the soft ballast system.
As you may know, I am contemplating an open bottom ambient design enclosed within the hull but, this gives me a headache with controlling a large free surface area when running on the surface. It may make sense for me to enclose these spaces albeit at the expense of more material to submerge but, the loss of the free surfaces would just have to make for better surfaced sea keeping.
I would like to ask you about what off the shelf components could I use to build solenoid controlled "flood ports" so that I could enclose my soft tanks and have them completely dry on the surface? That way my water ballast would not have any free surface. I would still use manually controlled and piped vents.
Nice schematic, you're an electrical guy aren't you?
Thanks
Joe

guyssee the pic on my frapper for the ballast system for my design will include the bill of materials in the next couple of days.Full redundant using a pressure comped hard ballast tank to save wieght,and split fore and aft soft tanks.rick m
