They are all close enough to walk to.
I would use Google Maps to walk it if you don't have enough money for a Lyft or Uber ride or a card for the Lyft bikes but make sure that you place a save location on your Google Maps so that you can get to and from places that you like in a multiple situation hope this has helped answer your question enjoy yourself.
All the ships are very close to each other & you can walk across or rent Uber Jump or Lyft bikes.
Fabulous walk to all 4! Very Scenic with all the shops and food/coffee
There are 4 ships. Constellation is at inner harbor. Chesapeake and Torske are 1-2 blocks west at aquarium. Roger b tawney is an additional 2 blocks west at pier 5. They are walkable , also water taxi green route goes between.
All the ships are in one location. I think there was only 4 ships there .if I'm not mistaken theres also a water taxi there .I parked across the street in parking deck and was able to walk everyplace I needed to go to see.
