Royal Navy officers have the privilege of remaining seated when toasting the Sovereign. Some sources state that this privilege was granted by William IV. A popular story states that Charles II was on board his namesake ship "Royal Charles" and had bumped his head on the low overhead of the wardroom when he stood up to reply a toast that had been drunk to him. He stated that henceforth, naval officers would never again rise to toast a British sovereign. In 1964, Queen Elizabeth II extended the privilege to the Royal Marines in honour of their 300th anniversary.
