Nope. It's just a lake. The water is perfectly good for drinking.
The original map grid was entirely ringed in land. It has several lakes but none of the water actually touched the rim of the map. I am assuming due to lack of contrary evidence that all the subsequent supergrids were generated similarly, so you won't be able to sail from one to the next.
However many requests for oceans have been made, so when the fabled next map reset happens we might just see one!
