I knew an older fella 90+ when I was young 13, who owned a 40+ foot yawl and he had a boom on his jib because he often sailed single handed. I remember him telling me this was the reason he converted it. He had actually converted the entire boat which was built in the 1920's from a gaff rig to the yawl configuration. I've forgotten how many people he told me it took to sail the boat in it's original configuration but it was MANY.
