The Texas belongs to the State of Texas but the actual brains of the Texas preservation effort is the Battleship Texas Foundation.

I know that there is about 25 million dollars (from a bond I believe) that is currently on hold as the intent is to build an infrastructure around the Texas....it's my understanding that the dilemma is for The BTF is that they have literally a sinking ship on their hands and if they can use all the money for the Texas's hull, it will probably take it all, they will not have enough for anything else. So part of the issue is to make the decision that the Texas has reached a point of no return if the hull repairs are not prioritized. Of course new funding sources will help...so the best thing people can do is contact the BTF and go from there. My expertise is not the Texas, but an even more urgent problem with the USS Olympia of 1898 (I am tied in with the main folks trying to save the Olympia from a national perspective--my book got me in with them=--but we are literally re-inventing the wheel and time is running out fast. The Olympia is an orphan, and as a result there is no money, but a lot of ignorance and apathy. The museum currently having the Olympia in it's trust is only doing emergency repairs trying to hold the Olympia afloat until someone else picks up the ship. Four entities are vying for it but they have no real funds and because the Olympia's plight was only recently publicized they are behind the curve. Folks supporting the Texas should be encouraged that there is infrastructure in terms of organization for the Texas, so it's just a matter of pitching in with the existing effort but also raising awareness, putting the pressure on so to speak. The Olympia and Texas are very similar in one way, they can no longer be taken out of their slips as they are not at all seaworthy, they need major repairs in situ. Both these great ships can still be saved, but time is running out.
