Day sailing around the bay with its shifty winds - very important. Once out of the bay - not so much. If you have a Windex on your masthead (although its a neck breaker) and a hand held wind meter you are all set. If I didn't have a Windex I'd buy one and put it up on the bow pulpit (if I couldn't get to the masthead) just to have something to keep referring to.
