The problem here is the fixed keel. Most sail boats like that have a very heavy keel, some with concrete or even lead in them to keep the keel down. Keel facing skyward is not a good thing. Just attaching a large boat to pull, or an excavator to push will make the keel dig into the sand and then it's not going anywhere. I think they had the right idea with the barrel weights on top of the mast pulling the boat over so the keel was out of the sand. That had to cause a huge amount of stress on the mast and rigging opposite the barrels, so maybe they are waiting for a tug boat and then try that again with the barrels and rolling it so the keel is out of the sand.
