Hi Mimi,
Actually, they screwed it up. Despite my giving them a diagram and exactly how to set the marks, they still managed to give us two downwind legs.
Luckily, with the wind we had the downwinds were still exciting. Otherwise they would not have been.
The class calls for the reaching mark to be 125% of the weather leg distance, out on a beam reach, either from the weather mark or the leeward mark. This allows for two pretty hot reaches. So you have two weather legs, two reaching legs, and only one downwind leg -- perfect for the Wave.
They set the mark at closer to 25%
Next year my brother-in-law, Dick BLiss, is opting to be on the mark boat to get it right.
The best course is to have the deepest reach first, and the beam reach second
