Also, you can make the boat heavier by filling the hulls with water, about half way or so, then after the storm you just pull the drain plugs. I put my Inter 20 on trailer, with the tongue on the ground, up against the lee side of the house last year and it didn't move in three storms.
My P19 survived a direct hit from Andrew about 13 yrs ago this week by this method. I was afraid of the point loading on the hull so I took the boat off the trailer first, though I'm not sure that was neccessary. Put the mast on the ground right next to a structure if you can't get it inside.
