"Tiger's boat Privacy has been docked at Old Port Cove in North Palm Beach for more than a week," the source tells PEOPLE. "On Saturday morning, after stocking up on provisions from Costco on Northlake Blvd., the boat left town."
Another source tells PEOPLE that Woods, 33, is going to cruise in the Bahamas for a few days after hanging around the Palm Beach Gardens area this past week.
Neither source has seen Woods, although tight security has been guarding the Old Port Cove Marina for more than a week. One eyewitness reported that a limo arrived at the marina Friday, before the boat departed the next morning.
In Happier DaysBack in 2004 while Woods and Elin Nordegren were just newlyweds, the couple spent their honeymoon aboard the tony $20 million vessel, sailing the Caribbean sea and visiting Puerto Rico. Among those guests they later hosted onboard included Bill Gates, Oprah Winfrey and Michael Jordan.
The 6,500 sq.-ft. craft, which has a range of 4,000 miles, is capable of crossing the Atlantic on its 12,000-gallon fuel tank at a maximum speed of 17 knots, according to Power and Motoryacht magazine.
Privacy also offers all the comforts of home and then some: a 2,000-gallon water tank, five guestrooms, a Jacuzzi, a gym, an elevator, a sky-lounge bar, a walk-in refrigerator, a deck dining area that seats 12, and two built-in wall safes. It reportedly sleeps 21 people.
