Hi, W and MBY! HAH! I thought it was Sir Francis Drake and that crowd plus a convenient storm, but what the heck do I know? I suppose Gandalf and a couple of fleets from Tol Eresseä and Alqualondë could have managed it...
I think it was Gandalf advising Sir Francis, Argh. And I'm fairly positive that Gandalf conjured the storm! :-)
