Upright hydrostatics lets you determine the hydrostatic parameters of the hull at a range of drafts, at zero or other fixed trim.

Select Upright Hydrostatics from the Analysis Type option in the Analysis menu or toolbar.

The following analysis settings apply for Upright Hydrostatic Analysis:

§   Draft from the Analysis menu, specify range of drafts for analysis

§   Trim from the Analysis menu, you may specify a fixed trim for all drafts

A range of drafts for upright hydrostatic calculations can be specified using the Drafts command from the Analysis menu.

Initial and final drafts can be entered, together with the number of drafts to be used. The Vertical Centre of Gravity is also required for the calculation of GM etc. This is specified as KG, i.e. from the baseline, which is not necessarily the vertical zero datum.

When a design is first opened, the initial draft defaults to the draft at the DWL as set in Maxsurf. Similarly the VCG defaults to the height of the DWL.

The following environments can be applied to the upright hydrostatics analysis:

§   Density from the Analysis menu

§   Wave Form (if any)

§   Hog and Sag

§   Damage (or Intact) from the Analysis toolbar
