Which organization is known for representing licensed deck officers and was founded in 1948?

The correct answer is the organization known for representing licensed deck officers and was established in 1948, which is indeed the AMO, or the American Maritime Officers. The AMO primarily represents licensed officers in the maritime industry, advocating for their rights, benefits, and working conditions. It plays a critical role in ensuring that members receive fair treatment and support throughout their careers at sea.

The founding year of 1948 marks a significant moment in the maritime labor movement, as it signifies a time when the need for professional representation for licensed officers became increasingly recognized. The organization's focus on licensed officers distinguishes it from others like SIU (Seafarers International Union), MEBA (Marine Engineers' Beneficial Association), and SUP (Seafarers Union of the Pacific), which represent different groups within the maritime workforce or have different focuses and priorities.

Therefore, AMO's specific advocacy for licensed deck officers, coupled with its historical inception in 1948, clearly identifies it as the organization in question.
