BHS (Basic HydroStatics) is similar in many ways to GHS, being a derivative or "subset" of the larger program.

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, 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, Crane, GHSCOM, Multi-Body, Programming Interface, or Sensor Interface modules. Since BHS includes most of the features of GHS, its price makes it a great value.
