I'm working on a ballast system for a new boat, here's what I've come up with so far. I wanted it as compact as possible so i've mounted the pumps up and made a custom manifold for the in & outs. 1&1/4" to the hull fitting, 3/4" to the left & right sacs, 1" to the front sac. The front sac will be a 700-800 pounder and the rear sacs will be 400's so I've doubled up the pumps going to the front. In theroy the fill time will be around 6-7 minutes. Uses impellar pumps, no need for valves & will be fully automatic.
The electrical system is almost finished, I'll post pics of that once it's done.
