A Quick Sink

Exploration Stage: Pier
From: Huntress
Description: In my childhood, a sailor told us stories from his youth, and I remember that Matrosov’s Anchor is the fastest and most stable. Find it, mein freund, if we want to save the Captain’s ship.
Completed: You’ve found Matrosov’s Anchor, but even it couldn’t hold the ship, although it can quickly dig in and turn around. We need something else.
