There is a question in the Facebook site about WindPaddles. WindPaddles can be used in Class 1 but it depends on the size and whether you are in a single or double. Class 1 allows 12 square feet per paddler. So a single paddler can have up to 12 sq feet and a double can have one or two sails that total up to 24 sq feet.
Note that some of the WindPaddles are slightly larger than 12 square feet. But we only use 2 significant figures so 12.04 is considered 12 sq feet for our purposes.
If you get sails larger than 12 sq feet per paddler, then you have to go into class 3 and I would strongly suggest amas.
