in Curves of Form is incomplete
We recently determined the displacement from the GHS Curves of Form
through the COMPONENT command. Then I ran a condition at the same
draft and got a different (larger) displacement in the STATUS report.
Why does the program give two different answers to the same question?
Am I missing something ?
You were using volumes of the HULL.C component. The HULL part consists
of two components: HULL.C and KEEL.C. If you had printed out the
KEEL.C curves of form you could have added the two volumes at a
given Reference Point Depth and gotten the total volume.
A better way is to use the HS or GHS command for your displacement
curve. These are for getting hydrostatic properties and they automatically
give you total displacement. The GHS command also has the advantage
of using draft for the independent variable.
As a rule, only PART totals are shown. If you want to delve down
to the component level, then you use the COMPONENT command.
