What would a 2D 17th Century naval wargame look like?

I continue to focus on the topic of what a 2D game would look like, so that we could fight Anglo-Dutch Wars battles. The maps need to be hierarchical. We need a high level map that we can click to select a region. We need a regional map that we can click to select a detail. On the detail, we would have our fleets, divided into squadrons and divisions. We could look at the composition of divisions, but would not seem them on the detailed map. We would have something that was similar to Iain Stanford's General-at-Sea miniatures game, except we would be able to see the details of what ships are in each division, and what their status is. We would not have to settle for combat systems that were so generic, but could use computer power to perform the gunfire and assess the damage. We would still have to make some compromises, in that divisions might stay with damaged ships. Otherwise, you start dropping off damaged ships. That is a possibility. It would be what we would really want, but would add to the complexity of the display.
