Narrow Seas (for Any Age of Sail Game) is a generic version of the scenario generator and campaign rules for Captaincy. It's a meta-game that supplements whatever Age of Sail rules you currently use. It depicts small fight-or-flight encounters between patrols, cargo ships, and raiders, using novel terrain generation and scoring rules to make these encounters very different from fleet battles. Plus, it's free.
