Overland hauling not a big issue here, where maybe 20% of the roads in the entire nation are paved. Besides, just about the longest trip one can make by road is less than 20 miles.
Your post made me think, though about beam. There is ONE travel-lift here, and I called them, and they THINK they could maybe squeeze 20 ft. beam into the slings and up thru the pilings.... No thanks.
I have been reading about suriviving hurricanes, and the concept of running her nose into a mangrove swamp, sitting on the sand at low tide, and tying her to bushes with stern anchors out....that makes sense. And we have lots and lots of mangrove swamps here. Home-made hurricane holes?
