There is two versions of Fish and Ships: Free and Pro
There is the same plugin, but PRO version comes with amazing extra features over the free: New selection methods, the ability of set different group criterion on every selection, 7 extra Special Actions and of course, upgrades and prioritary support.
However, the free version is fully functional, and is hosted on wordpress.org repository.
