SS Amicus and SS Parabellum are two additional ships that have been procured, made from two old Sherwood-class vessels. They carry much more cargo than the Ian-class ship. SS Amicus is being used by Doorstop to demonstrate sails and hydrofoils. NEW ONE! SS Igitur.
@CarCrazyKid for the original ship, er, class SS Amicus is now Porcupine's flagship, and has been involved in debris recovery from Doorstop V
