I have a quick question for someone in the know, is my H-17 Sport with one up legal to sail in the Alter Cup qualifier or do I need to set it up as a uni-rig? I have heard that they don't allow modifiers so any help is welcome. My crew for my 20 is kind of sitting the fence as she sailed this past weekend and doesn't want to impose on grandma again.
Thanks in advance.
