Keeping his/her vessel and crew out of danger
A pleasure craft operator can moor their vessel to a signal only in cases of emergency or when it is necessary to avoid immediate danger. Otherwise, it is not recommended to moor a vessel to a signal as it may obstruct navigation or pose a safety hazard to other vessels.
A vessel signals its bearing by the position where the signal flag is hoisted on the ship. For example, if the flag is hoisted on the starboard side, it indicates a bearing to the starboard side of the vessel. In this way, signal flags are used to communicate information about a vessel's orientation and position to other ships.
