This "Bow Tie" course is a no brainer. 3 laps. 11 turns, 6 one way, 5 the other, and some left and right surfing action through the waves. Surf back in 3 times left, 3 times right. You paddle back out "direct". Surely, this is the solution! ??
^ this is a 4.0km paddle course.
PS - Jacko, your course would get people lost


(too many turns / irregular shape)... This course is as simple as you can make it. A fun little "cross roads" bit in the middle too. Kind of like Slot Cars!
