Don't forget to build the pond so it looks like the Med & Atlantic on one side and the Pacific on the other side. Put a dome over it we so we can battle in AC and in the winter. Make the bottom sandy so the ships have a soft landing on the bottom. Make it shallow enough so my shorts don't get wet. Make the shore sloped so I don't have to step down to get the ship. Have lots of tables, with concrete under them so I can find my set screw when I drop it. Put in speakers so we can listen to AC/DC, no German music! Locate it near a major freeway so we can get there easily. Needs to be near a town big enough to have lots of places to eat, but not too close so the city grows out there and takes it over.
Bob, you forgot the need for a nearby campground and motel, sparkling restroom facilities at the pond, good wifi signal, lots of 110 electrical outlets, and a nearby Radio Shack and hobby store.
