Overview
Trimper's Rides is a historic amusement park and boardwalk entertainment business located near the inlet at South First Street and the boardwalk in Ocean City, Maryland. Its roots date to 1893, when Daniel B. Trimper and his wife, Margaret, operated boardwalk property and hotels in the resort town. The enterprise was initially known as the Windsor Resort, a name associated with the Trimpers' hotel, theater, and amusement facilities. Today, the business is commonly identified as Trimper's Rides or Trimper Rides of Ocean City. The park occupies three outdoor lots and an indoor amusement area. Its attractions combine modern rides with preserved mechanical amusements and historic memorabilia. The indoor section is especially associated with family and children's rides, antique ticket booths, operating vintage equipment, a shooting gallery, bumper cars, and a collection of William F. Mangels kiddie rides. Its centerpiece is a large Herschell-Spillman carousel purchased by Daniel Trimper in 1912. The carousel includes 45 animals, three chariots, and a rocking chair and is regarded as one of the oldest continuously operating carousels in the United States. It was designated a historic landmark in 2007. The outdoor areas contain a broader mix of family rides, thrill rides, and attractions. Listed attractions have included Tidal Wave, a 126-foot looping roller coaster; Endeavor; Himalaya; Spinning Coaster; Tea Cups; Tilt-A-Whirl; Rock N Roll; Balloons; and a Fun Slide. The park also operates the Mirror Maze and Pirate's Cove, a walk-through fun house designed by Bill Tracy and built in 1971. Pirate's Cove is described as one of only two surviving attractions of its type in the world. The Trimper family expanded the amusement operation in stages. Outdoor rides were added during the 1950s, and expansion accelerated from the middle of the 1960s, when the park generally added a new ride nearly every year. In 1964, Granville Trimper worked with designer Bill Tracy on the Haunted House. The following year, Daniel Trimper III assumed leadership and substantially expanded the property through the acquisition of land and attractions associated with Melvin Amusements. In 1985, the park acquired Tidal Wave, a triple-loop boomerang roller coaster that became one of its best-known outdoor attractions. Trimper's Rides also operates Marty’s Playland, a boardwalk arcade that has been open since the 1940s and offers a mixture of classic and newer games. The combined business is positioned around seasonal seaside tourism, family entertainment, heritage attractions, and the continuity of a long-running Ocean City boardwalk institution. Publicly available material does not establish a current corporate owner, a current chief executive, or detailed financial results.
History
Trimper's Rides developed from the Trimper family's nineteenth-century resort business in Ocean City, Maryland. Daniel B. Trimper and Margaret Trimper arrived in Ocean City in 1890 and by 1893 controlled boardwalk property between South Division and South First Streets, including the Eastern Shore and Sea Bright hotels. After a major storm damaged the Sea Bright in 1900, the Trimpers rebuilt it with an appearance inspired by Windsor Castle. The hotels, a theater, and an amusement park were subsequently associated with the name Windsor Resort. A major heritage asset entered the business in 1912, when Daniel Trimper purchased a large carousel manufactured by the Herschell-Spillman Company of North Tonawanda, New York. The 50-foot carousel originally operated with a steam engine and featured 45 animals, three chariots, and a rocking chair. It remains in operation and was recognized as a historic landmark in 2007. The carousel and other antique attractions form the foundation of the park's indoor presentation, which also includes vintage amusement memorabilia, antique ticket booths, William F. Mangels kiddie rides, bumper cars, and a shooting gallery. The business began adding outdoor rides during the 1950s. Expansion accelerated from the mid-1960s, with the park adding attractions at a pace described as approximately one new ride per year. In 1964, Granville Trimper collaborated with Bill Tracy on the Haunted House. In 1965, Daniel Trimper III took over leadership of the park and nearly doubled its size by acquiring land and attractions from Melvin Amusements. John and Maria Bilious were later engaged to restore the Herschell-Spillman carousel. Daniel Trimper III retired in 1981 and leadership passed to his cousin Granville Trimper. The park acquired the Tidal Wave triple-loop boomerang roller coaster in 1985. Other notable attractions include Pirate's Cove, a Bill Tracy-designed walk-through fun house built in 1971, and the Mirror Maze. Tidal Wave and Pirate's Cove represent the business's combination of conventional thrill rides and themed walk-through experiences. The operation also includes Marty’s Playland, a boardwalk arcade open since the 1940s. Across its indoor and outdoor facilities, Trimper's Rides has maintained a business model centered on seasonal Ocean City tourism, family recreation, boardwalk nostalgia, and the preservation of historic amusement equipment. The supplied reference material does not identify a current executive team, ownership transaction, financial performance, or a separate national operating network.
