Why is a submarine called a boat, not a ship?

[mapuc]

Found this interesting issue on FB.

The terminology distinction between "boat" and "ship" in the context of submarines has historical and traditional roots, and there are a few reasons why submarines are commonly referred to as "boats":
1. Historical Terminology:
The term "boat" has historically been used for smaller vessels, while "ship" has referred to larger sea-going vessels. This classification system dates back centuries and has its roots in maritime tradition.
Early submarines were relatively small compared to surface ships, leading to the use of the term "boat" to describe them.
2. Size and Function:
Submarines are typically smaller than many surface vessels, and their size fits the traditional concept of a "boat." The size definition can vary, but generally, "ships" are larger vessels capable of carrying more cargo and having more complex operations.
In naval operations, smaller vessels such as frigates or corvettes might also be informally referred to as boats, further reinforcing the term's association with submarines.
3. Cultural and Naval Traditions:
In naval culture, submariners often refer to their submarines as "boats" as a point of pride and identity. This tradition reinforces camaraderie and a sense of belonging among crew members.
The phrase "down in the boat" is commonly used among submariners to describe their life on a submarine, further entrenching the nomenclature within the submarine community.
4. Conventions in Other Languages:
In various languages, including those of other naval traditions, the term for submarine often translates more closely to "boat" rather than "ship." This can influence the terminology used in English-speaking navies as well.
5. Distinction from Surface Vessels:
The use of "boat" helps to distinguish submarines from surface vessels, providing a unique identity within a fleet. This distinction can be particularly important in communication and operations.
In summary, while both terms are often used interchangeably in casual conversation, the historical, cultural, and traditional factors contribute to the continued use of the term "boat" when referring to submarines in naval contexts.
