This software reads hull shape data from an offsets file (edited by hand in a text file) and calculates section areas and therefore, by numerical integration, the displacement and all relevant coefficients, such as block, prismatic, and waterplane area coefficients. Stability data can also be derived, including transverse and longitudinal GM. It would be feasible to get this program to produce righting arm curves, but this will not be implemented in the first versions.

This software is being developped in PHP so that it can be web based, and therefore available to the internet community. The source code is available as well.

This being an open source project, it is provided without warranty of any kind, and requires the support of users and developpers to progress further, so if you can help in any way, you are welcome to contact us.

Current version is 0.02, which is to say that the features are still very limited. The next step will be to import data directly from some types of files, making it MUCH esaier to use. The data file format is quite simple. For the moment, it is as follows:

Station 1
Xpoint1 Ypoint1 Zpoint1
Xpoint2 Ypoint2 Zpoint2
.
.
.
Xpointn Ypointn Zpointn
Station 2
Xpoint1 Ypoint1 Zpoint1
etc...
