In ship construction, what are the hull frame members extending athwartship referred to as?

The hull frame members that extend athwartship (side to side) in ship construction are known as transverse frames. These frames are essential for providing the ship with structural integrity and shape, as they help to distribute loads throughout the hull. Transverse frames play a critical role in reinforcing the hull against bending and twisting forces, especially during rough sea conditions, ensuring stability and safety.

In contrast, longitudes run in the direction of the length of the ship, providing longitudinal strength and support. Stringers are typically longitudinal members that enhance the strength and rigidity of the structure, while web frames are usually part of a hybrid framing system that can include both transverse and longitudinal elements but are often used in specific structures like the bulkheads or the deck structures.
