The vessel names on SpaceX's two Dragon recovery ships have been painted over.I checked US [Coast Guard] databases and can confirm that GO Searcher and GO Navigator are being renamed to Megan and Shannon respectively, in honor of SpaceX's first two female astronauts.
This news comes sixth months after SpaceX chose to name their two new support vessels Bob and Doug.
I can't see any ownership paperwork filed but Searcher and Navigator are no longer listed on the Guice Offshore (GO) website. I would suspect SpaceX has bought the ships from GO.
