The program can evaluate a full set of hydrostatic parameters for any value of pitch or heel. An example of the program's three hydrostatics displays is below (both metric and British units are supported):
At a heel angle of 0.000 deg
Pitch angle is -0.131 deg
Water density is 64.063 lb per cu.ft
Sinkage is -0.012 ft
Volume displaced is 7.495 cu ft
Assigned hull displacement is 480.000 lb
Total displacement is 480.000 lb
Righting moment is 31.048 lb ft per deg.
Mass per unit immersion 2284.058 lb/ft
Moment to change trim (MCT) 142.182 lb ft per inch
Waterplane area 35.654 sq ft
Wetted surface 37.523 sq ft
Whole hull surface area 100.049 sq ft
Whole hull surface LCG 7.231 ft
Whole hull surface VCG 0.479 ft
Overall length (Loa) 14.000 ft
Waterline length (Lwl) 14.000 ft
Maximum beam (Bmax) 6.007 ft
Waterline beam (Bwl) 3.685 ft
Draught (T) 0.385 ft
Midsection freeboard (Fm) 1.744 ft
Profile area above waterline 23.256 sq ft
Profile area below waterline 4.078 sq ft
You can also write the information on this screen to a disk file, cross plot any of 24 internal variables (e.g. righting lever against heel), and write tabular summaries to a disk file. Below are couple of sample hydrostatic cross plots.
Hullform also provides a flexible ability to produce a range of
stability and hydrostatic tables. You can choose the stability
variable from KN, GZ or righting moment, and the columns of your
hydrostatic table from a list of over 50 internal parameters.
The dialog box shown here illustrates the process of selection
- you have control of both the entries used, and their location
across your table.
If you want more, see the entry for Hullstat, which provides almost total control over any hydrostatic report format.
