What are the horn signals for manuvering a boat?

Horn signals for maneuvering a boat typically include short blasts and prolonged blasts to communicate intentions. One short blast indicates the intention to alter course to starboard, while two short blasts signal a course change to port. A prolonged blast is used to indicate intentions in reduced visibility or to signal danger. It's essential for boaters to understand and use these signals to ensure safe navigation and avoid collisions.
