There is big difference between RIB (RHIB0)
https://en.wikipedia.org/wiki/Rigid-...nflatable_boat
and the blow up / fold away inflatable version.
RIBs are the workhorse boats often used for commercial, military and rescue operations for the RIb's ability to safely handle rough seas.
As TimeOff has pointed out a quality RIB is far from portable or cheap.
