You will need shut of vales for each tank (or a manifold with valves) for a
number of reasons. With out valves:
1. All water will flow from the higher tank to the lower one.
Which tank is higher can change with each tack. This moves significant
weight from where you want it to where you don't.
2. Contaminated water (it can happen) in one tank will contaminate the
other.
3. When the higher tank runs dry the pump (pumps?) will suck air and
lose prime, preventing you from drawing water from the lower one.
4. You don't get the ability to keep the smaller tank as a reserve
supply.
5. If you put a tank under the V berth, with valves you can empty that
one first to get weight out of the ends.
That's all I can think of off the top of my head.
