Since there a landmark to follow in the middle of the ocean, it was easy to get lost. Because of this, Abel opened the digitalization ability of his world stone fragment as soon as he left the Dividing Earth Basin. He created a visual map inside of his brain and followed it pretty much ever since he was above water.
Every time White Cloud traveled for a while, Abel's brain would automatically update the map. He couldn't get lost, so that he couldn't take any breaks this whole trip. Actually, he didn't even know how long he would spend before he actually found the island. Obviously, he was tired, but at least the druid spirit was there to help him expend a lot of the mental power needed for this kind of work. This way, he could still read books and occasionally glance at the spiritual beasts that would come out of the water.
