Description:
This spreadsheet automatically computes trim, forward draft, after draft, metacentric height and stability margin.  It also computes

Electronic Document Type:  Microsoft Excel spreadsheet          Cost: $35.00 US funds

Number of Pages: single sheet                        

Inputs:  

  • The vessel's Light Ship weight and centroids, vessel length, vessel condition being evaluated (i. e. departure, arrival, 45% burnout, etc.)
