18 (Chinese: 永裕興18號) was a Taiwanese fishing vessel found adrift and unoccupied near Midway Atoll after losing contact with shore.

Taiwanese authorities concluded the crew was lost due to a weather event.

Built in 2001, it is 29.6 metres (97 ft 1 in) long, carries a crew of 15, and is equipped with at least one freezer.

The boat was left adrift in the Pacific Ocean, and the US Coast Guard continued to search for the missing crew.

They found there were "no signs of physical altercations, blood, or explosions", but there were "multiple structural damages found on the hull [...] indicat[ing] the boat underwent strong wind waves from multiple directions".
