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.)

  • The following is required for each item on board:

    • Weights and centroid information for passengers, crew, dry consumables (provisions and stores) on board.

    • Weights and centroid information for cargo (dry and liquid) on board.  Free surface information is required for the tanks carrying liquid cargo.

  • After the above information is entered use the total weight obtained as a basis for the following data input:

    • Input the following Curves of Form data:  Draft, LCB, LCF, KMt and KML

    • Input the Maximum Allowable KG, or VCG, this is an optional input, but required if you want to compute the stability Margin

Outputs:  

  • The total weight and centroids of the vessel in the condition being evaluated.  This includes all fluid weights present.

  • The total free surface effect for all the tanks involved.

  • The trim present, the trim angle, the forward draft, the after draft, corrections for free surface in KG, the metacentric height and the stability margin.
