I have spent the last 3 weeks of lockdown writing an App to do race course design. It is able to handle standard or random courses,  and it is very flexible. Any mark,start,finish or gate can be moved, rotated etc Standard courses can be loaded, scaled, rotated. It calculates the course length a race time depending on the wind speed. (For a Laser)  It can also use GPS to help place the marks correctly. I intend to leave this a Free App open to all.....

Please try it out.   https://ood-online.com/CourseDesign.html  

Any comments would be appreciated.....
If anyone has any ideas I could incorporate, I will always add acknowledgements.

Looks good.
My club uses 7 fixed buoys and a movable 'X' buoy (to set the start gate), 90% of the time the prevailing wind is a south westerly, first leg is a beat, first turn is always to port, second turn is again to port, these 2 buoys (number 4 and 3, start between 7 and the 'X' buoy) are very close together, the zones are almost touching, you go from a beat to a broad reach and a gybe onto a run, this causes loads of errors in a blow, water a boats width to starboard also shallows very rapidly so takes a brave helm to attempt a overtake, from Buoy 3 you run to 6, which is a starboard turn, (very close to the bank and overhanging trees) most of the buoys have issues.
Will your app work with a course like this?

Nothing will work with a course like that!

Can't see any reason why not.  You can fix the position of any of the Marks.  Port/Starboard is automatically assigned unless you specify the mark as always port or starboard..  You are also able to name the marks  to meet you local names...  Eg The X bouy will be named 'X' and be able to be moved around. You can put the X buoy at one end of the startline and 7 at the other end.

It just needs a map image of your venue in the  background to make sense.

Need to make our course technical, longest leg is only 600 metres, we use every buoy, boats are crisscrossing, adds to the excitement.

How complicated do you need?  There are no limits to the number of marks,  where they are placed, or the number of times you can go round.  You can even have a mark you go round to port and starboard on different legs  You can have a separate start & finish and a port starboard gate...

Bouys are clockwise from jetty, 1 to 7, 1 and 7 are at opposite ends of the jetty, 1 is about 300 metres away and 7 about 30 metres away, longest legs are 1 to 5,approx' 600 metres, second longest 1 to 4 about 400 metres, closest together 3 and 4, zones are almost touching, Bouys are in numerical order clockwise in a rough oval, pool about 20 acres.
Course for a south westerly, Start between 7 and the 'X' buoy, beat up to 4, port turn to 3 (Broad reach) , port turn to 6 (run), starboard turn to 2 (reach), port turn to 1(Broad reach), port turn to 5(reach) port rounding to 7(broad reach), end of lap. Number 1 buoy only one with plenty of room round it, 5 buoy is in a 90 degree corner wind shadowed by large trees, very tricky.
