It's already been said about the boat being light and the seas stopping their forward motion, however, if you keep the
jib sheeted in it will back wind and help bring the bow around. Also if you move some weight forward in the boat in these conditions it will come about better. I sail Lake Michigan all the time and we get some wind up here. As far as a storm
jib goes, you can make a small one yourself. It will be flat, with very little drive, but you want it mostly for balance, not drive. I just used 3 yards of cotton canvas to make mine. Bought the hanks, put a good heavy hem around it and used the material I had cut off to double around the tack, head and clew. I did a button stitch around the holes where I put the grommets, then some sewing glue then the brass grommets. Same at where my 5 hanks went in. Cost about $70. It would be a lot less if you can find some used hanks. Adding some weight down low and forward will make her sail much better in these conditions. Just bring another cooler of beer along, and stick it up by the vee berth.
