From the initial spawn point, there's one to the north (say about 1:00 o'clock from spawn). Yag is right at the southern tip of the landmass...the plains area is small, has a mountain to the north and a swamp very close next door to the east. There's a small forest area above that on the east side.

There's also one to the west and a little bit north. It's a much larger landmass and Yag is on the east coast. Sail up the narrow'ish channel between two continents.

Those are the closest...and neither are relatively close. I'd probably go for the northern one but it's likely 12 of one or a dozen of the other.
