* AluminumChristmasTrees: "Legal pirates" seems ridiculous, until you hit [[Website/{{Wikipedia}} the history books]] about {{Privateer}}s.
* SugarWiki/AwesomeMusic: The score. Mainly [[https://www.youtube.com/watch?v=Aisrod8dMaA Daikoukai Jidai]], the bit of music playing during the Introduction Sequences and Next Time trailers of each episode.
** The ear worm of an opening and (regular) ending could also count.
*** Especially the full version of the opening.
*** The full version of the ending is pretty much the definition of SugarWiki/AwesomeMusic. You know, if you cranked the trope up to eleven.
** Hakuoh Jogakuin, the Leitmotif of Jenny and the Yacht Club, which plays the AdventurousIrishViolins to the hilt.
* BigLippedAlligatorMoment: In episode 25, the chef is accompanied by twelve-foot tall humans who shake the ground with every step. Nobody notices or comments on it.
* CrackShip: [[CargoShip Chiaki/Parfait.]] Given her LesYay with Marika, some have suggested a three-way relationship. Four-way if you include Gruier. Just three consenting girls and a consenting chocolate dessert.
** Marika/Hat.
* FanNickname: Grunhilde Serenity is sometimes referred to as "Loli [[Anime/MobileSuitGundamCharsCounterattack Char]]" due to the uniform she was wearing when she was first introduced, which, combined with her hair and eye color, eerily resembled the titular character.
* LauncherOfAThousandShips: Marika, so much in the yuri fandom.
* LesYay: Quite subtle aside from Jenny and Lynn. Marika/Chiaki. Marika/Gruier[[note]]Gruier once bought Marika a suit. Marika usually wears a short skirt. Marika thought the miniskirt on the suit was too short. Gruier argued vehemently that it was perfectly fine.[[/note]] Marika/Mami. No wonder some fans joke about Marika's "harem".
* LGBTFanbase: The anime has gotten some attention from the yuri fandom thanks to its large amount of female cast and the fact that WordOfGod stated that there is no romance. [[YuriFan Yuri fans]] presumed that he meant "there is no male/female romance", especially after [[spoiler:Jenny and Lynn started exploring each other's tonsils onscreen]]. And with that said, Marika gets shipped with ''a lot of girls,'' specifically Chiaki, Gruier, Grunhilde, and Mami. Interestingly enough, Marika and all those girls are seen together in one part of the ED sequence.
