Well basically the story as I remember it, was that Javelin was bought by Stratos around the turn of the milenium. And for a few years, Stratos built both the Stratos line and Javelin which was basially sold as a line within the Stratos family. Then a point came in time where the Javelin name was eliminated and they went with Stratos.
Stratos itself is owned by Genmar holdings which is a company that owns a bunch of boat brands that you would be familiar with.
Here's a link to their site which lists their brands.
