A Ukrainian cargo ship was sheared in half by heavy waves after it anchored in the Black Sea near the coast of northern Turkey.

The ship's crew had dropped anchor off the coast, hoping to ride out a storm since the vessel was designed for river travel and not the massive breakers of open-water in foul weather. From January 15 to January 17, the crew attempted to wait out the rain and heavy winds.

Instead, this happened:

(Warning: Intense)

Another nearby ship captured the sinking of the vessel:

The Ukrainian-owned Arvin was traveling from Georgia (the European one) to Bulgaria when it sank. There were reportedly 12 crew members onboard, including two Russian nationals. Six were rescued.

There's a lesson here about ship maintenance as well. As someone who grew up in Michigan, I know at least something about boating on open water. The last time the Arvin was inspected, she had some major issues, including significant rust and corrosion and poorly maintained hatches.

That's a big no no.

So whether you're sailing the waters of the Black Sea or traversing that pond behind your uncle's house, make sure to batten down those hatches and make sure your boat is shipshape before venturing into the unknown!
