Centerboard Meaning in Sailing

A centerboard consists of a heavy retractable plate located in a slot under the hull. This board provides the lateral resistance needed to sail toward the wind without sliding. Sailors can raise or lower the board using a rope or a manual winch. This feature allows a boat to enter very shallow water without hitting the sandy bottom. It also helps the boat stay upright by providing weight and grip in the water. One specific example involves a sailor lowering the wooden board before starting a race. This action allows the boat to sail at a sharp angle toward the first mark. When sailing away from the wind the crew raises the board to reduce drag. This simple adjustment increases the speed of the boat when lateral resistance is not needed. Most small sailing dinghies and some large cruisers use this versatile and helpful equipment. Regular cleaning of the board slot prevents sand and small rocks from getting stuck.
