Sailing

Start, finish, and gate legs run to the middle of the G–F and F–X lines. Bearings magnetic (var 12.5°E); published distances from the club chart. The forecast is sampled at every mark — the small arrows on the chart show the local wind for the hour you pick above, and the ★ sits on whichever end of the start line that wind favors. Est. times assume a ~20 ft boat (≈5 kn upwind and reaching, slower in light air, tacking through 90° when a leg is dead upwind) starting at the selected hour; each leg’s wind is the forecast at that leg’s own transit time. Hover a buoy for its coordinates.
