BHS (Basic HydroStatics) is similar in many ways to GHS, being a derivative
or "subset" of the larger program.
BHS includes:
- hydrostatic properties
- curves of form
- cross curves of stability
- load condition status
- heeling and trimming moments
- wind heeling derivation
- righting arm curves and areas (with constant trim or constant trim moment)
- tank characteristics and soundings
- damage stability
- stability on waves
- intermediate stages of flooding
- tank CG shifts
- and much more!
BHS produces high-quality reports with graphs and has the same wide
recognition and acceptance as GHS.
On the model-building side of the system, BHS comes with both Section Editor -
the graphical hull modeling tool - and Part Maker which makes it easy to build
all sorts of tanks, compartments and appendages into the model.
Most of the GHS optional modules are also available with BHS. These are,
- Model Converter
- Longitudinal Strength
- Load Editor
- Condition Graphics
- Floodable Lengths
- Tank Soundings
- Grain Shift
- Hull Maker
What BHS lacks relative to GHS is, most noticeably, the automatic stability
criterion evaluation facilities of GHS with maximum-VCG solving. BHS cannot
change the axis of heel, it lacks the tonnage calculation, and it does not
have access to the Advanced Features, Multi-Body or the Programming
Interface modules.
Since BHS includes most of the features of GHS, its price makes it a great
value. It also retains its value because it can be traded with credit for its
full purchase price for an upgrade to GHS.
