Just think historical with RSRD or you may get bored. The action is seldom at your patrol star. Pay attention to the action reports why docked, the lil movies telling what's happened what's coming or just learn history.
This is a good link for RSRD. Study the battles and invasion forces, dates and routes they take and you'll find plenty of action. For instance study the invasion of Java. Late Feb to early March you'll run into many large invasion forces along the coast of Java.
The Solomons campaign is great with RSRD, from the battle of Coral Sea, the Port Moresby invasion group, battle of Savo, Santa Cruz, ect...
Study up.
