So no, the captain is not only interested in navigating. He is interested in not getting torpedoed.

You can zig till your heart's content without taking any bearings whatsoever. He needed the bearings for navigation purposes. The point being that the two situations are not remotely comparable. The skipper of the Lusitania has much more information before he takes the first bearing, than any U-boat skipper would have of a potential target.
