THOSE WHO EXPECTED TO SAIL on one of the three ships of American Cruise Lines will need instead to file for a refund of their deposit.

The cruise line has filed for Chapter 7 bankruptcy protection with the United States Bankruptcy Court in Hartford.

After completing its 1988 schedule, the cruise line, which sailed from the Eastern Seaboard, filed for Chapter 11 protection to reorganize before converting to Chapter 7, meaning that it must liquidate and sell off its assets.

While it could not be determined how many passengers had deposits with the cruise line, a court official said that the Bankruptcy Court had sent 1,300 notices to passengers and to creditors. Their insurer was the Aetna Casualty and Surety Company of Hartford.

Those with deposits have three avenues to get their money back. Claims, including all relevant documents, may be filed with:

Aetna Life and Casualty, Bond Claim Department, One Civic Center Plaza, Hartford, Conn. 06103; 203-273-0123.

United States Bankruptcy Court, 450 Main Street, Room 717, Hartford, Conn. 06103.

American Cruise Lines, One Marine Park, Haddam, Conn. 06438.

The case number, 288-01-225, should be given.
