Ten more Regions have been added to the seas of Second Life: Pequod's Doom, Stubb, Ahab's Haunt, Flask, Melville, Queequeg, Looming, Rachel, Ishmael, Tashtego. The Map function is still catching up with them, I'll add some individual SLURLs when it's updated.
They feature lots of open water, an island with a mysterious skeleton, and lots of underwater content for the swimmers and mer-folk. There are two rez zones, both in Ahab's Haunt (look for the docks); and no doubt some racing marks and start lines will appear soon.
For now, teleport over to Peleg and look north. Have fun!
