I agree with you up there but not quite:

We all know, Kuma was part of Dragon's crew, which without a doubt is legendary, now, they are the type of guys that i think traveled the whole world, for various reasons, like: Gathering informations or specializing plans to overthrow the World Government, also creating hideouts, looking for people to join their army... many other reasons that i don't think i need to mention. So what i'm trying to say is that Kuma can't send someone in a specific location or island without him never being there.Rayleigh is a man but he has been there,the same might go for kuma.

other theory:

Raftel is in another dimension!!!!!!!!!!!!!!!
