Nautical Term: MBL

Definition of MBL

Minimum Breaking Load (MBL) refers to the minimum amount of force required to break a rope or cable under normal conditions. This value is essential for ensuring the safety of marine vessels and other structures that rely on ropes or cables.

For instance, when setting up an anchor system, the minimum breaking load of the anchor chain is a critical consideration. If the MBL of the chain is not sufficient to support the weight of the vessel and the anchor, there is a risk of the chain breaking, which could lead to catastrophic consequences for the vessel and its crew.
