Hi Mugrace,
My Wave has a main and a jib. I turn downwind gently until the Jib moves over to the other side but the Mainsail stays on the other side. I have to be careful not to turn too far otherwise I end up Jybing.
Regards, Tim
OK now that makes sense. Actually, mine came with a jib but I have never used it.
I should give it a try.
