The board's purpose is to investigate the circumstances related to Tuesday's sinking, 75 miles off Cape May. The panel hopes to develop conclusions and recommendations to improve the safety and operations of similar vessels.

The National Transportation Safety Board will participate.

During an interview with the Coast Guard, the sole survivor was unable to shed much light on what might have caused the sinking.

Services for two of the men who were recovered are scheduled for Monday in North Carolina.
