The ruined perfect boating weekend

I am sure most of everyone that owns a boat has had a perfectly planned out weekend with all your friends and on your boat ruined by the weather.  I absolutely hate when that happens, because here you think you are going to have a perfect weekend/day out on the water with your friends or family.  I think it is one of those things that really grinds your gears.  Its those sudden storms that just kill the weekend, the ones that the weatherman doesn't predict.  Yeah those, those stupid storms or  fronts that cause an unexpected storm to brew or a windy cloudy  day.  One time this happened to me a couple of years ago and from now on i really don't trust the weather sometimes.
