Lost at Sea and in Another World

Tirpitz of Iron Blood finds herself transported to another world of shipgirls when she got lost during a storm. In that world, she meets shipgirls who fights Abyssals rather than Sirens. She then gets taken in by the Maizuru fleet who she hopes will help her return home, but an old foe is trying to eliminate her and the shipgirls. (Revised version. Original is in FFN)
