Way beyond my scope to Mike, chuckling.... Sailing away from the storm would be my guess This is what Jim Brown said "with technology in weather forecasting you should never get caught out." my bit, " unless your a crab fishermen trying to make money."
I wouldn't go cruising in this design. Its intercoastal/coastal speed demon. Never getting more than 100 miles off shore more like stay around 50 miles close.
