Your post has absolutely NO DETAILS, so generallities is all you will get. Do you have any idea what it costs to move a boat? What size boat are we even talking about? I sold a fresh water boat that in hind sight I wish I had moved to salt, but I also bought a salt water boat and moved it back to the same fresh water I had left. Details will get you a much more meaningful response. Generally, a fresh water boat will be in better condition, ALL variables the same, than a salt water boat.
