********UPDATE 7th June 2020: FBD Version 3.0 is launched! Please note that FBD V3.0 is available on an annual subscription basis. Please write to us after purchase at [email protected] to get the license key.
The following improvements have been implemented:
Updates in V3.0:
1. Cb calculation now changed to one based on volumetric displacement, to avoid the user having to input density
2. The formula for superstructure correction for Type B ships updated to calculate effective length before calculation of tabular freeboard
3. Pool length and forecastle length now changed to freeboard length, as the sheer correction table is based on freeboard length
4. Displacement changed to volumetric displacement in report
5. All references to Le/Lf changed to Le/L to avoid confusion in report
6. The Loadline image in the report has been removed due to non-conformity in resolution across different devices
