Forum:Quick Question about Grandline Islands

Are they all on one of the Seven Routes?

Following the journey of the Strawhats from Twin Peaks to Saboady Archipelago, somewhere in the midst of getting Vivi to Arabasta, the crew stopped following their natural Grand Line Route, and it's debatable as to whether they took a shortcut or took a different route all together.

However, has it ever been said that all the islands in the GL are definitely on a magnetic route? Currently all the islands met in the Grand Line by the Strawhats have been in the Paradise Half, and therefore before Saboady Archipelago. This would mean that Karaigana and the Boin Archipelago, the places Kuma sent Zoro and Usopp respectively, were also on routes and would have been met by the 1/7 of crews (an average) who were set on that route and survived thus far.

However, the atmosphere and description given of both islands gave the impression that these islands didn't have regular visitors.

I know that Oda is only one guy, and it could just be an abberation, but assuming Boin Archipelago is on a route, and few people make it to the island, and you can expect even less make it out, that there would be talk somewhere (definitely at Saboady Archipelago) of there being no survivors of a specific route. Or in the other case, that the route Zoro would have been sent to, is the island home of a Shichibukai.

It is possible that the magnetic fields of certain islands are too weak, or they are just too far out to naturally be picked up by one of the seven routes, which would then explain islands such as these, but more over I just wanted to know if it's definite that all islands are actually on a route.
