BSB 4 & 5 chart support is almost ready for testing. We hope to begin beta testing the new version at the end of this week. All beta testers, please check the testing forum for an important announcement.
BSB 4 & 5 support will only be available in the Retail version of SeaFarer.
This will be the last Qt3 version of SeaFarer. SeaFarer version 2.0 will be Qt4 based. We will also be releasing it on Mac OS X and Windows Vista. In the next couple of weeks the product site will be updated with all of the new info on SeaFarer.
Here is a small screenshot of a BSB 5 chart in SeaFarer.
