Boat closest of the mark : Jiel
second boat closest : Samuel
Next mark direction is deduced by the Flow's course at the bottom of the image
Jiel is entilted to mark-room from rule 18
Mark-room is : room to round the mark as necessary to sail the course
Room must allow : manoeuvring promptly in a seamanlike way
Samuel didnt give that room because our boats hitted.
