The configuration of this set of objects allows the creation of a hullform database and the comparative
analysis of the hydrostatic and powering properties of the hullforms. New hullforms can be created from
known offset data or by distorting existing hullforms. A variety of distortion techniques are available
which include scaling, geosim, Cp and LCB shifts.
The offset data is then converted into a facet model using GRC’s own innovative “offsets to facets” technique.
This allows much more accurate hydrostatic and hydrodynamic data to be inferred from the geometry than in
the case of using, for example, Simpson's rule. The hullforms can have a variety of further comparative
analyses done on them which include Moor Murdey, body plan comparisions, CSA comparisons. Regression analysis
is also available which allows the user to perform a regression in the powering domain on any number of
selected hulls. The output of such regression can then be used in conjunction with Paramarine’s powering
functionality to achieve more accurate and realistic powering predictions. A variety of tank test data
can also be stored in the database for further analysis.
