Trim & Stability Sheet (Metric Units)

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: $25.00 US funds

Number of Pages: single sheet                        

Inputs:  

bullet

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

bullet

The following is required for each item on board:
bullet

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

bullet

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

bullet

Weights and centroid information for consumable liquids carried (fuel, water, etc.).

bullet

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

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

bullet

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

Outputs:  

bullet

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

bullet

The total free surface effect for all the tanks involved.

bullet

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.
