Every charter boat I have taken out had two anchors. The issue in CGB is not the wind it’s the swell. They come from two different directions. A anchor keeping you into the wind would put the boat broadside to the swell.
That's not what I was watching on the video all day. The boats were stern to the swell most of the time and occasionally broad-side which is why I said they were getting Thrashed!
I spent all my money on "Boats", "Broads", and "Booze"; the rest I wasted!
