According to Naomi, who arrived on the Island by parachuting from a helicopter dispatched from the freighter, the crew formed part of a search and recovery team, hired by Penelope Widmore, but the freighter mission was actually set up by her father, Charles Widmore, through Matthew Abaddon in order to find the Island. When the rest of Naomi's team arrived in a second helicopter, they were not looking for Flight 815 or its survivors. Some of the team thought that the plane was supposed to have been found off the coast of Bali, in an ocean trench four miles deep. Others were informed about the real plane crash, but didn't expect there to be survivors.
The name Kahana was first seen on the ship's starboard side when the helicopter approached it in 第4季第5集.
"Kahana," according to a Hawaiian Dictionary, means "n. Cutting, drawing of a line; turning point. Cf. kaha 1, 3. Eia maʻaneʻi ke kahana alanui e iho ai i kahakai, here's the turn of the road to go down to the beach." There are many places in the Hawaiian islands called "Kahana," and "Kahana" is also a proper name for men or women. In addition, if spelled "ka hana", this could mean "the work" in the context of a larger sentence.
Additionally, "Kahana" is the aramaic form of the word Cohen in Hebrew, which means Priest but also Leader. All Jewish priests came from the family of Levi, who was the son of Jacob.
Scenes with the Kahana were filmed at sea a few miles off the coast of Oahu. The ship docked at Barbers Point just west of Pearl Harbor. The actual ship is used to transport supplies to islands and science research stations within the Hawaiian Archipelago. (4x05e)
