Ya, my limit is being able to see the horizon in the troughs. Was a strong wind warning issued for the north channel, forty miles North of where I was. The biggest and steepest was coming out of an inlet, but after that got turned and ran parallel to them making it not so bad. I found it got a bit squirrelly running with the waves and less tab helped. Needed a bit more power to climb the waves when running with them also. Biggest test was my wife. Never been in big stuff before. Aside from work boats my experience has been with a 36 cigarette, our family boat years ago. Was impressed with how the Grady handled the longer term driving in the ups and downs. Despite normally going much faster, you did not sit in the cigarette. Although much slower, I never was out of my seat in the Grady. At the end was running in some threes and was up to 37 mph or so. Loving that bow spray!
