Well that is a matter of opinion, but when your running across the bay, you will see boats cutting towards the bridge as well as fishing boat sitting in what is the channel. The bridge will be on your right and you will feel like you should turn and you can if you stay on plane. But if you want to follow the channel you need to make like the bottom of a letter "Z" and stay straight in the channel towards the buoy by the land. You will feel like your gonna run up on the land, then make a sharp cut back almost SW to head up towards bridge. Fishing boats may be blocking alot of these buoys.
So when you pass red 10 on starboard, hold that course until you pass red 12, then cut up to green 13. You will lots of boats cutting this corner.
