"As we have never shown an interest in, let alone found money to preserve warships as Museums, this is the inevitable fate for most."
Slightly harsh (and untrue) - there are plenty of warship museums in the UK, and worldwide. The main problem they have though is finding the money to keep them going as a long term asset.
It is phenomenally expensive to keep a warship (or any ship) going as a museum ship due to the need to keep the hull maintained. The US is on the verge of scrapping the USS Olympia (a very old 1890s historic cruiser) as the lack of money available to run her means her hull is litterally paper thin in places, and she is in danger of sinking. Other US museum ships are being put into permanent dry dock to stop the hulls breaking.
Most museum ships are a real struggle to run succesfully as a business - HMS CAVALIER (last WW2 RN destroyer) took nearly 30 years to find a succesful home where she is loved - and shes a fraction of the size of Vince. Similarly, other museums, such as the HMS PLYMOUTH trust and other places struggle for funding. Outside of a couple of core locations such as Portsmouth and Chatham, there is no real location where you can moor a ship permanently, maintain her and keep sufficient people as passing trade to make money.
Ultimately I'd like to see a cold war escort preserved as part of the national historic register, but I don't think a CVS is a credible vessel to do this.
