What does Type B-60/B-100 correction pertain to regarding freeboard corrections?

The Type B-60/B-100 correction pertains specifically to vessels equipped with steel hatches and enhanced water freeing arrangements. This correction is critical for accurately calculating freeboard, which is the distance between the waterline and the upper deck level. The enhanced water freeing arrangements are designed to allow water that may collect on deck to drain off more effectively, thereby reducing the risk of water accumulating and affecting stability.

In vessels with steel hatches, this correction acknowledges the structural differences and ensures that the freeboard values are adjusted appropriately for the design of these hatches. This adjustment is vital for determining the vessel's safety in various sea conditions, particularly with respect to stability and seaworthiness.

Understanding this correction is essential for anyone involved in stability calculations, as it ensures that the vessel meets the necessary regulations and maintains safety standards during operation.
