Mouretsu Pirates, Aoki Hagane no Arpeggio: Ars Nova Recommendations
This show reminded me of Mouretsu Pirates in a way. If you enjoyed this i think you might also enjoy Mouretsu even more.
Girls controlling ships (well in mouretsu's case space ships)
Fight in Oceans/Space
Don't want to tell too much just give it a try if you don't like it in the first few episodes then whatever.
They're both sci-fi and ships are a big part of both of the shows.
