It depends. A
RIB will hold more, is more stable when planing and obviously more rugged when beaching. What you give up is the ability to store when sailing especially
offshore.
For
long term cruising I like my 10' ft
RIB with a Yamaha 15 hp
2 stroke. It is light enough that I can manage it if I need to remove it from the dink. When you are anchored all the time as I am a fast reliable method of transportation is highly desirable. The problem comes with
storage. I am fortunate to have a stern platform to carry my RIB and mounted
motor on my
catamaran. Many cruisers, especially monohulls carry their dink on the foredeck while traveling. I have seen lots use
davits or small inflatables.
To Answer more definatively, I would need to know how you plan to store it, where and how long you are cruising and are you on the hook or using
marinas.
