Thirty-five of the 37 people on board were rescued. Two are still unaccounted for. The Duck boat is at the bottom of the Delaware River.

The Duck boat was stopped in the shipping channel because of an engine fire that prompted the crew to cease operations, according to the Philadelphia Inquirer. They were waiting for a rescue boat to come get them.

The National Transportation Safety Board has launched an investigation into the accident. Board member Robert Sumwalt will be on the scene, holding regular press conferences.

What if you worked on a boat that spent weeks, or even months, out at sea? You don’t have much of a commute to work, but when your shift is over and it’s time to go to sleep, you’re not climbing into a roomy, comfortable bed. You’re climbing into a bunk on a moving vessel. The engine is still running in the background, the room may not be dark and there are other crew members running around above deck because now they’re on watch.

You may have a generous amount of time set aside for shut-eye, but is that quality sleep you’re getting?

Does all this sound familiar? Would you be willing to talk to a reporter about your experiences and take a video camera with you the next time you shove off? Get in touch with Ariel Zirulnick, who is reporting on issues of marine safety, at ariel.zirulnick@news21.com.
