Travelers are not class legal. Not to mention they don't give you much advantage either in most cases.
Downhaul or Cunningham allows no moving blocks.., only 8' of line.
The sail must measure in.
That is about it.
Don't know where you are located, but there a lot of venues going now for Wave racing. Upcoming really quick is the Midwinters East in Panama City, the last weekend of March. Should be a good one. We think we will have at least a dozen boats in the class.
