Although
Mouretsu Pirates was (mostly) a lighthearted anime series that romanticized pirates and piracy into more of a stylized cosplay for entertainment (rather than a "serious business" of cutthroat life/death and loss of liberty) ... it still managed to pull off some pretty incredible things that were totally unexpected.
Things like having a 200 year old solar sailing "yacht" that has been donated to a girl's high school which has
A HISTORY (no spoilers) that none of the students on board at the time really knew about.
Cat & Mouse battles involving EW capabilities ... with an unexpected outcome (see episodes 2.75, 3, 4 & 5, english dubbed:
LINK).
HIGHLY 
recommended as an inspiration for how to handle organized unwanted/pirate encounters in a
Traveller campaign, starting from while docked at the highport (the opening narration of Episodes 3, 4 & 5, pre-titles are especially useful to ALL spacer crews!)

The curious parallels between nautical sailing (wind and waves) and orbital navigation into aerobraking descents to a world surface ... and how that kind of skill has multiple applications in different contexts is a recurring theme throughout the series.
Even more surprising, the series has
plenty of schoolgirls wearing skirts in zero-G ... and not a single (gratuitous) upskirt view at ANY time throughout the entire run ... which, considering the "demand" for Fan Service™ in the anime market is honestly quite remarkable.
