Capsizing is when a boat or ship is turned on its side or overturned. The act of reversing a capsized vessel is called righting.

If a capsized vessel has sufficient flotation to prevent sinking, it may recover on its own if the stability is such that it is not stable inverted. Vessels of this design are called self-righting.

Small dinghies frequently capsize in the normal course of use and can usually be recovered by the crew. Some types of dinghy are occasionally deliberately capsized, as capsizing and righting the vessel again can be the fastest means of draining water from the boat.

A capsized kayak may be righted with a roll or eskimo rescue. As long as the kayaker knows how to react, the water is not too shallow, and the location is not close to dangers which would require evasive action by the kayaker - which cannot be taken while capsized - capsizing itself is usually not considered dangerous. In whitewater kayaking, capsizing occurs frequently and is accepted as an ordinary part of the sport; depending on personal experience, the difficulty of the water, and the preferred kayaking style (esp. playboating), many whitewater kayakers likely capsize several times each time they go kayaking.

Henry C. "Hank" Johnson Jr. (born October 2, 1954) is the U.S. Representative for Georgia's 4th congressional district, serving since 2007. He is a member of the Democratic Party. The district is based in DeKalb County, a largely suburban county east of Atlanta. It also includes portions of Gwinnett and Rockdale counties.

Johnson grew up in Washington, D.C. His father worked for the Bureau of Prisons and was the director of classifications and paroles, up to that time, the highest ranking African American in the bureau.

Johnson graduated from Clark College (now Clark Atlanta University) in 1976, was a member of Omega Psi Phi Kappa Alpha Alpha Chapter, Decatur, Georgia, and Texas Southern University's Thurgood Marshall School of Law in Houston in 1979; he practiced law in Decatur, Georgia, for more than 25 years.

He was elected to the DeKalb County Commission in 2000 and served two terms. Prior to his service on the Commission, he worked as an Associate Magistrate Judge for ten years.

Johnson is—along with Mazie Hirono of Hawaii, also elected to Congress in 2006—one of the first two Buddhists to serve in the United States Congress.^{[citation needed]}
