You do not need the chart.
This an example that I use to teach set and drift, CMG, SMG, CTS, Speed.
On November 18, 2003 we plan on leaving Thieves Bay Marina, Mouat Point Light (Lat 48°46.5’N Long 123°18.75’W) for Isabella Island (Lat 48°43.75’N Long 123°25.75’W). We will use the current information for Swanson Channel. The chart shows the flood direction to be 360. Using our current prediction tables, we determine that that the drift is 1 knot. Our boat speed is 5 knots. Our course to make good is 242T. We need to gauge our speed made good and our course to steer.
