SOLUTION:
Forward Draft =
13'- 11''
13.916667
After Draft =
11'- 09''
11.75
Mean Draft =
12'- 10''
=
12.83'
Displacement =
6,130
Maximum Forward Draft =
28'- 06.75''
28.5625
Maximum After Draft =
28'- 06.75''
28.5625
Mean Draft =
28'- 06.75''
=
28.56'
Your vessel's drafts are: FWD 13'-11", AFT 11'-09". How much more cargo can be
loaded to have the vessel down to the freeboard draft? (Use the information in Section 1,
the blue pages, of the Stability Data Reference Book)
Red = table values, etc.
Green = ANSWER
Blue = information provided.
Black = calculated values.

For the Forward and Aft drafts provided, determine your vessel's Mean Draft.
Using the Mean Draft, enter the Blue Sheet 1 - Deadweight Scale and
determine the Displacement, and the Maximum Freeboard Draft.
