Course 1 was 1.8 and course 2 was 2.7.
Lengths printed on the description sheet are short. If you have a description sheet that was not manually (pen) corrected, add 50% to the length. Eg course1 printed said 1.2; it was really 1.8. Course 2 said 1.8; it was really 2.7.
Also, those (corrected) distances were straight line - not the IOF sprint standard of shortest passable route. So by IOF standards they should be even a little bit longer.
