Gusts and Lulls: Helm and Trim Response
The wind is ever changing, sometimes chaotically and sometimes in more predictable ways. The atmosphere holds clues as to the strength of a gust and what direction it will come from or if there will be any gusts at all. Foreknowledge of gusts lets us optimize boat speed and course while avoiding dangerous jibes and knock-downs. The changing direction and speed of wind in gusts and lulls is evaluated for effect on apparent wind, sail trim, and helm response.
