I'm partial to the Lightship HURON. The last lightship to serve on the Great Lakes. In lower Lake Huron close to Port Huron, my hometown. It is unique among lightships being painted black vs. the standard red.

Lightships are named after the station they serve over. There never was a station named 'Portsmouth' - that name was given after the ship was retired and placed in the city of Portsmouth.

Chesapeake is the only one of the three you mentioned that actually still is floating. (Huron is nestled in 'dry dock' next to the St. Clair River.)

These are great additions to your Harbour Lights collection - and at half price - you could add all four ships.
