Re: Tornadoes and boats...
Interesting question. There are just so many variables. Are you talking about a small water spout or a monster F3 or F4 tornado? What kind of straight line winds are associated with it?
Looking at the damage photos from out west I would think a direct hit would tear apart a fiberglass boat - after all they take down brick/block buildings. But I have to wonder about the boats ability to move. Palm trees do better in wind storms than oaks because of their greater ability to bend and move with the wind and their lower windage. A boat can bob and heel, a brick building can't, and there's a lot less windage on a boat than a building.
I wonder if any Sailnetters have experienced a tornado going through a marina?
