I hated the sailing so much, mainly because there is so little to do and to complete everything in the game you need to sail the same bits of sea over and over again. For example, doing the Goron trading quest meant sailing the same stretch of sea over and over again as only one of the islands that had a Goron on it could be warped to. People talk about Wind Waker having a large overworld, but if you take out all the bits of empty sea then actually there is not much there. For me, Zelda should be about exploring a location the first time you are there, but then being able to navigate quickly afterwards, Wind Waker doesn't really do this (Ballad of Gales can only get you so far, you still need to sail quite a bit to get to most islands).
