It has been reported that the real estate developer and casino operator has been squeezed for cash and that he has been under pressure from a slowing of the casino business and the enormous debt he amassed through his various businesses. He has denied that he or his businesses face a liquidity problem.

Mr. Trump, who has put the Trump Shuttle, his airline, up for sale, has said he wants to raise cash to purchase other assets at distressed prices. Last month, Mr. Trump said he planned to sell the yacht to build a bigger and better one.

Mr. Trump bought the Trump Princess, as the well-known yacht is called, for $30 million in 1987 from the Sultan of Brunei, who had secured it as collateral for a multimillion-dollar loan to Adnan M. Khashoggi.

Mr. Khashoggi, a Saudi Arabian arms dealer, reportedly spent $85 million to build and outfit the vessel with such features as a helicopter landing pad, a screening room and 800-film library, a discotheque, a hospital, sleeping quarters for a crew of 52, bathrooms of hand-carved onyx, and refrigerators that can carry a three-month supply of food for 100 people. The yacht has 14 fuel tanks that allow it to travel 8,500 miles without refueling.

In 1989, the Princess was leased by the Trump's Castle hotel and casino and berthed at an Atlantic City marina. It was used for promotion and entertainment by the Castle and several other Trump enterprises.
