WindPlot will allow user to automatically log the water temperature or depth for each new mark made. Further, he can instruct WindPlot to print this information on the plotter screen. This requires temp. and/or depth instrument outputting the proper NMEA 0183 to be connected to WindPlot. The sentence for depth is $SDDBT and for temp. is $YCMTW. Then by just clicking the right mouse button a mark is made at the vessel's position with the current water temperature or depth printed next to it. See the temperature example below.
