Looking for lesser known, obscure movies/series dealing with large bodies of water

I just finished watching "The Rig" and it's put me in the mood for aquatic horror. I've seen the majority of the more popular ones, starting from the 70s (I'm old).

I'm looking for movies similar to:

The Boat (2019)

Below (2002)

Cold Skin (2017)

Sea Fever (2019)

The Bay (2012)

I've seen both versions of "The Lighthouse" and all the Lovecraftian ocean/water based horror.
