Typically, the junior officer of the deck has the , (i.e., control of the engines and rudder). The junior officer of the deck is relieved in a similar manner. The deck and or the conn may be assumed by the captain, simply by announcing the fact or by issuing an order to the helmsman or lee helmsman. For example, the captain may state, "I have the deck and the conn," or "I have the conn," or "Right full rudder, all ahead flank." In the latter case, someone (ordinarily the junior officer of the deck) in the pilot house (or bridge) will announce, "The captain has the conn." The conn may also be passed to someone else, for a particular purpose. While the captain may assume the conn, the officer of the deck may order the junior officer of the deck to pass him the conn, "Ensign Pulver, pass me the conn." Ensign Pulver will then state, "This is Ensign Pulver, Lieutenant Doe has the deck and the conn." Lieutenant Doe then announces, "This is Lieutenant Doe, I have the deck and the conn." In an emergency, the officer of the deck can, if he so chooses, assume the conn by announcing, for example, "This is Lieutenant Doe, I have the conn. Hard right rudder, all engines ahead flank." However, in most ships, during normal underway operations, it is generally considered "poor form" to request the JOOD to pass the conn, as a good OOD would be expected to direct the JOOD without the necessity of assuming the conn himself. Thus, the distinction between having the "deck" and having the "conn" remains.
