Text Box: turns into a continue button which can be pressed to continue the simulation. All other functions or buttons are available while paused. Cloud % Gives the cloud cover in percent at the boat position. One-hundred percent is total cloud cover. Pressure This gives the surface air pressure in millibars at the boat’s location. Temperature This gives the air temperature at the boats location. It is fun to watch this when you head south. Rain When rain is falling at the boats location a text box appears indcating light, moderate or heavy rain. Waves This group gives wave heights which are determined using a mathematical model. Waves are dependent on wind speed, wind duration and fetch. Wave heights are not well defined near storm centers such as hurricanes where competing effects are not well handled by the mathematical model. Pressure Trace This provides a graphical depiction of the pressure rise or fall over a forty-eight hour period. You can think of this as an aneroid barometer trace. Date/Time Group This provides time information for the voyage. The current Greenwich Mean Time date is shown in abbreviated form, e.g. July 21, 1993 is shown as 21Jul93. The Greenwich time GMT is shown in hours and minutes for a 24 hour clock. The Local Time at the boats position is also shown in hours and minutes for a 24 hour clock. The Compass This gives a graphical depiction of the boats heading. This compass gives true heading not magnetic heading. The buttons The buttons below the compass steer the boat. The port button steers the boat to the left. For convenience the buttons also give the direction to head-up (into the wind) and fall-off (away from the wind). Depth/Speed The depth at the boats location is given in fathoms ( 6 ft) in English and meters in Metric Location/Movement Group This gives information on the boats position and movement. Lat and Lon give the latitude and longitude of the boat in tenths of degrees. Negative latitudes apply to the Southern
