On Monday afternoon, the 43-foot vessel Piper was approximately two miles offshore from Hawaii, near the island of Kaho'olawe, a small volcanic island. The boat ran over a large piece of rope used to tied up ships - called a hauler line- which was then entangled in the propeller. The rope was so caught up that a hole was torn in the vessel, at which point the boat started to sink.
The ship's crew sent out a Mayday signal, and attempted to save the vessel by cutting the entangled line and bailing water, but once the boat continued to sink and electrical power was lost, they abandoned ship by boarding a lifeboat that was onboard.
