If you are just craving the ocean, these two are great picks. The narratives are quite different, but the nautical settings are fantastic in both. One is a romance/supernatural drama and the other is simply about a fishing club, but both focus heavily on human coexistence with nature, specifically the sea. I'm massively biased towards anything ocean-related, so these two both did wonders for me. Perhaps they will do the same for you.
