As one swallow does not make a summer, then one trireme clearly does not make a fleet (see below, the complete [or first stage] collection of Greek triremes, the two square bases were just products of experimentation to see what works, but they may also have a use representing a Navarch):  

This is „my starter for ten“ Greek fleet with three squadrons on ten each, plus two command ships – or a left, middle and right of the fleet if I put the individual ships into sabots of bigger bases. Nothing deciding bar the need for flexibility of thought. As for the rules to use .. plenty of options, watch this space in due course 😉
