The SS Princess Louise was a 331-foot steamship constructed in 1921 in North Vancouver, British Columbia. Named in honor of Louise, Princess Royal and Duchess of Fife, a granddaughter of Queen Victoria, the vessel was part of the Canadian Pacific Railway's "Princess" fleet, serving as a coastal liner alongside the "Empress" fleet that operated trans-Pacific and trans-Atlantic routes. Known for its luxurious amenities and superior class of service, the Princess Louise was considered a "pocket liner," offering a level of comfort and elegance comparable to larger ocean liners, despite its smaller size. Designed primarily for tourist service to Alaska, the Princess Louise operated on a 1,750-mile round-trip route between Vancouver and Alaska until 1964. During its service, it was regarded as a luxury cruise ship of its era, providing passengers with a refined travel experience along the British Columbia coast. The vessel's construction and service reflected the maritime importance of regional coastal liners that combined transportation and leisure. After being retired from passenger service, the ship found a new life as a floating restaurant in Los Angeles Harbor. Purchased by Jerry Sutton, the Princess Louise was moored at Terminal Island and opened for business on September 25, 1966. It quickly became the largest floating restaurant in America, attracting nearly 2,000 guests daily. In 1979, the vessel was relocated to Berth 94 in San Pedro. However, by 1984, the restaurant was struggling financially, and despite a change of ownership to Marion Perkov, the business continued to decline, ultimately closing on January 15, 1989. Following its closure, the vessel was seized by the Bank of San Pedro. While being prepared for resale and repair, the Princess Louise unexpectedly capsized at her berth on October 30, 1989, with suspicions of foul play leading Lloyd's of London to withhold insurance payout. Ultimately, the ship was intended to be sunk as an artificial reef near Catalina Island. However, while being towed on June 20, 1990, it took on water and sank prematurely at a depth of 900 feet, far from its planned final resting place.
