Re: Miss Liberty vs the landlubbing haters!
If you get the boat moved, what will you do with it then? If it does not receive significant repair (at some significant expense and if it is repairable or worth repairing), you'll have the same problem again in a different location. And if it is repairable and you intend to do it, why not earlier and how could you let it get into current condition (before it was stripped)?
If you can get the bottom area around the keel cleared away so that the bottom is not restricting the heeling, you might get a large horsepower motorboat to connect to the top of mast (i.e. halyard or similar) and while the motor boat gently pulls very hard at roughly ninety degrees to direction that you want to move your boat, you might be able to heel the boat over sufficiently at high tide to work it towards deeper water. Assuming your engine isn't working at this point, you'll need a boat on the bow to pull your boat while the other power boat is heeling your boat. All this assumes that the standing and running rigging are up to the task. Also, moving ballast (anything heavy) to one side can help achieve the heeling.
The 500 gallon stainless steel tank....why that size, how was it installed, and how was it removed? Really 500 gallons? 1 gal/hr x 5 mph = 2500 miles.
