Difference between Zodiac FC-470 and F-470?

[Awesomeness]

Would someone please explain the differences between the Zodiac FC-470 an F-470? I know the FC stands for "Futura Commando", so without the "Commando" what changes? I also see these written places essentially interchangeably. Thanks!

Same boat different name but there have been multiple versions including 15”,18”, and 20” shaft transoms. Airfloors, roll up , and solid decks as well.
