You have been given some good advise. Just attempt to stop the pounding.
I also agree with Siamese.....you don't want to find 8' to 10' ers on L. Michigan. However, if you do, don't forget to look back when you start up the next wave. That wall of water looks like it is 20' and coming to get you. Don't stop!
5' waves are relatively calm. It feels like 8' is double 5' and 10' is just huge. On rare occassions the lake can stir up some really big stuff of 15'+ but that is far more than small craft warnings and you have plenty of notice. The freighters are hiding behind something for those mothers.
Your boat should handle 8-10', as mine can, but I try not to get into that position as I don't handle it nearly as well as the boat. Almost lost a wife a couple of years ago in 8's, and it was not because she was going over board. The only reason she would be standing up would have been to kill me for putting her there. We survived it, but now SHE checks the weather forecasts on the rare day she sails with me.
