I would have to say Epona or the Crimson Loftwing. Epona was awesome, easy to manuver, and was very useful. The Crimson Loftwing was awesome, the controls were outstanding, and just what it is, is just cool. :chu:
Sailing in WW will always have that magical and adventurous feel for me. Sailing made the whole game feel like an epic quest in a way i'd never known before and still feels meaningful, it was also amazingly relaxing some of the time. I still sail calm waters to pass time on slow days. =]
I can feel the hate about to come in, but my favorite is The King of Red Lions (the boat) from Wind Waker... because of all the things u can use on it, Boomerang, Arrows, A Cannon, A Crane, The Sail, and the telescope.
I'm actually very specific on this one for an odd reason XD
I have two favourites, warping (from any of the games) for time saving reasons...
Or Epona in TP ONLY, and only because I love the horseback field music, because it is actually different than the on foot field music. So even though I warp everywhere in TP, when I have a bit of extra time, I ride Epona in the field so I can hear that awesome song<3<3
