The snag with solenoid valves is that most of the readily available miniature versions are designed for flowing air and gases, not water. If you use them with water the internals can corrode. There are suitable solenoid valves available, but they tend to be larger. Okay on a bigger boat, but a problem on something smaller.

The Festo valves I menioned certainly aren't very stiff, and are easily turned by a standard servo. Pinch valves work well also, but it's something you will need to make yourself. Fortunately not that difficult to construct.
