No, boats aren't in the game as far as I know. My character was part of the frog-people race and could swim in water. I'm not sure what the numbers represent, though I do remember the far western island was inhabited and had a mine, it was called Farcliffs.
I think there are. At least it seems we have some in the kitten's village, and an expedition is being prepared out of the island. Don't know if it's only RP, though.
