Ship Data - Main Dimensions

The 'Main Dimensions' page enables you to input the main dimensions of the vessel, the principal draft information that is used for design, and the vessel's tonnage. Initially the 'tonnage' may be the target or required value, however this sheet can be updated as and when the tonnage calculations have been undertaken. Again, this information is generally required for the typical report that Calc is arranged to produce.

The Subdivision Length (Ls), its aft end position, Subdivision Loadline (ds) and Lightest Service Draft (d0), are parameters used principally in the Probabilistic Stability Assessment.
