Wish I could be more help
Mike,
There is nothing that I am aware of other than marina slips. And there may not be a lot of them. Most that are back up and operating are pretty full. Far as I know there is no help from the gummit, or any other entity. You are pretty much on your own far as I know. TonyB may have some info on this also, as he was here during Katrina and lost his boat. Other than the marinas, there are lots of homes here where I live, that have docks and no boat. Might be possible to tie up to some of them, for a very small fee, but it would almost take a door to door inquiry to find them. Might place a small add in the local paper, and ask. I could do this if you would like, and see if there is any response. Other than that I don't know of anything else. There are only two travel lifts that I am aware of operating on the north shore. If there is anything more I can do, just let me know.
