The 80' Tender Kupreanof sank early Wednesday, June 10, 2015. The crew can be seen displaying calm preparedness in an emergency situation, beginning the evacuation by jumping into their Imperial immersion suits. The raft quickly deploys.

The ship sank rapidly, so the crew did not have much time to act. Fortunately, they continued to keep level demeanors and moved quickly through the evacuation process, jumping overboard, but remaining protected against rough seas and cold temperatures in their immersion suits.Fortunately, the Coast Guard was on the scene within minutes, and each member of the 4-person crew was individually picked from their raft and air lifted to an MH-60 Jayhawk Helicopter.
