Re: Tools for Setting Marks for Yacht Races
I have developed a MAP version draft.
It needs a Smartphone with GPS - which I don't have (!!) and so I need some one to give it a try and to provide some feedback
see setcourses DOT com/try.html
This tool provides a virtual GPS unit for Laying the Marks.
=> Enter the Lat Long for the Reference Location Mark 3 or click RefLoc to set it for your location.
=> Enter the windward direction and your preferences for the reach angle and leg length, Then Click GO.
=> This will display a map showing the Mark layout and their positions.
=>Then, to set a mark, proceed in its direction. Click the ShowMyLoc button to show your current position as a 'dot'. Click it again and your new position will be plotted. Click GO to clear the 'dots'
=> If you need to relocate the marks due a wind shift, without moving the bottom reference mark (Mark 3), then simply enter the new direction and the altered position of the marks will be displayed.>To change the reference, either enter its new location, or go there and click MyLoc to reset all the course marks.
=>Note: Click MyLoc and ShowMyLoc buttons twice for better accuracy
=> A Smartphone with GPS is required for accurate positions.
