Currently you can use Autocad or a similar program to open export 3D Boat Design files to.
The file extension you can export/import your files as is a .DXF file type
You can also export to Blender/3D Max in both dxf and .obj.
There is also the possibility to import the files into several other animation programs.
If you need a different file type you will need to convert it in your current program.
