Ever since this country was young, a strange creature has been sighted in the Chesapeake Bay. This creature, unofficially known as Chessie, is said to be a dark tubular or snake-like animal averaging 20- 30 feet long and capable of swimming up to 10 MPH. Chessie is known to be sometimes curious of nearby humans and is not afraid by those who work and live on the Bay, and who might therefore chance upon it. The creature is still seen intermittently. concentrations of sightings occur in May through September most likely because that is when the Bay is most populated with boaters and swimmers. Chessie has been sighted most often are Love Point at Kent Island, the mouth of the Potomac, and the Eastern Bay.
Chessie was by all accounts not your typical Longnecked, Humpbacked, Plesiosaur-shaped sea monsters. Instead, Chessie seemed to be truly serpentine and traveled along in a serpentine motion, in broad horizontal sine-curves or closer-knit sets of squiggles.
In May of 1982, the first hard evidence of Chessie’s existence arrived. While at their Kent Island home, the Frew family, along with friends, believed they spotted Chessie and they made a videotape. Mr. Frew and his wife were looking out at the bay when they noticed a large snake-like creature. Frew and his wife spotted the creature in shallow, clear water about 200 yards from the house. The Frews grabbed their camera and started recording. That video tape was later analyzed by people at the Smithsonian. It was determined that the creature taped was a living animal. Frew video taped the creature as it swam toward a group of swimmers. It dove beneath the swimmers and reappeared on the other side of them. The creature they saw was about 25-30 feet long, 1-2 feet in diameter, dark brown with aa undulating back. In 1978, a retired CIA employee, Donald Kyker, also reported seeing Chessie and 3 others about 75 yards off shore. His neighbors, the Smoots’, also witness the creatures. They gave descriptions of a 30 ft, sleek, dark gray creature swimming about 7-8 miles per hour.
In the summer of 1982, the Smithsonian had a mini-symposium to determine if the videotape was indeed evidence of Chessie’s existence. Along with the video, there was a photograph taken by a woman who was previously afraid to bring it to public attention. The officials concluded that the object was definitely alive, but they did not conclude what it was. The creature in the Bay was left Unidentified.
Although a manatee was discovered to frequent Chesapeake bay and frequently migrated to and from it, the descriptions of the manatee do not match the creature and there is virtually no chance that the manatee is responsible for any of the sightings, still photos or video footage.
[On the other hand, every now and then a sighting in the more typical Plesiosaur mode also pops up. At the beginning of the Wikipedia's entry on Chessie, it states:
"Chessie is a legendary sea monster said to live in the midst of the Chesapeake Bay. Over the years there have been many alleged sightings of a serpent-like creature with flippers as part of its body. According to Matt Lake in Weird Maryland, two perch fishermen, Francis Klarrman and Edward J. Ward, in 1943 spotted something in the water near Baltimore.
“This thing was about 75 yards (69 m) away, at right angles from our boat. At first it looked like something floating on the water. It was black and the part of it that was out of the water seemed about 12 feet (3.7 m) long. It has a head about as big as a football and shaped somewhat like a horse’s head. It turned its head around several times—almost all the way around.”1
