Cool Water Sailing

I'm going sailing on Lake Michigan on a Hobie Cat on Tuesday. I am praying that my sailing knowledge is still sound even though I have not sailed in years. I do not want to turn this boat over. The water in Lake Michigan is too cold for this Florida boy.  I keep trying to remind myself not to Jibe if the wind is too strong. Nothing wrong with a chicken jibe. Once I get used to the rigging I will feel more confident.
