Nautical Term: Isherwood system

Definition of Isherwood system

The Isherwood system is a specialized method of framing a vessel. This technique utilizes closely spaced longitudinals, which are the primary framing members running lengthwise along the hull.

In addition to these closely spaced longitudinals, the Isherwood system also employs extra heavy floors spaced further apart. These floors, also known as transverse members, provide additional strength and rigidity to the vessel’s frame.

For example, imagine constructing a large ocean-going cargo ship using the Isherwood system. The vessel’s frame would consist of closely spaced longitudinals running lengthwise along the hull. These longitudinals would be supported by extra heavy floors spaced further apart, providing additional strength and rigidity to the vessel’s frame.

In conclusion, the Isherwood system is a specialized method of framing a vessel that utilizes closely spaced longitudinals and extra heavy floors spaced further apart. This system provides additional strength and rigidity to the vessel’s frame, making it an essential technique for constructing large and robust ocean-going vessels.
