Nice monologue, but it depends on what's there.
Wind Waker's sailing was tedious because there was nothing to do for minutes on end on a flat blue field of nothing. The HD version anyway fixed some things because of the Swift-sail which besides the added speed also eliminated the need to redirect the wind, something that originally slowed down things greatly and hindered freedom. I remains a big ocean though, literally, of nothing.
Zelda U at least got Wind Waker beat in that part; riding around on a horse through a varied landscape is loads more interesting than sailing in a straight line.
The sailing wasn't even the only (or biggest) problem I had with Wind Waker though. It was way, way too easy. Moreover there were too few dungeons which were also too short and again too easy. These things were adressed by Twilight Princess, though also still easy it wasn't that easy, and Skyward Sword (and even the handheld titles) so I'd expect the line of progress to continue.
