Tide-Line Blue

As far as I'm concerned there's an anime about pretty much everything if you look hard enough: diving, underwear design, insurance investigation (yup!) and don't even get me started on cooking. So there, picked titles with main characters directly involved and at least some focus on whatever they're doing for a living or a hobby or both.

Part two^ https://myanimelist.net/stacks/30206 (it's a work in progress though)

Shows where ships play some fairly notable part in the story. Stack is biased toward ocean-going vessels. Submarines are also included.

anime i have found on mal
is it good? is it bad? YOU MUST DECIDE

Ocean Productions has a sister studio for cheaper dubbing efforts in Alberta, the shows they worked on are as follow!

The release dates are kinda outta wack, i tried to organize them best as a good but info on the cardfight dubs are far in between. I also excluded some series like Deltora Quest because although they dubbed the show, they didnt dub it all. I also excluded their joint productions with their main studio, Ocean, as those can be found in the the Ocean movie/ova stack.

Anime that takes place underwater, involving water ships rather than spaceships.

This stack lists various anime with coastal, oceanic or maritime settings. They may be "ocean worlds" or just involve shoreside locations (e.g. a seaside town); however, they all share a setting characterised by proximity to a marine environment. Naturally, each series has varying levels of emphasis on these nautical elements.

Anime centered around ships of some sort, mainly spaceships, airships, and submarines.
