Could Majestic-class ships have changed 1898?

Would three Majestic-class battleships have allowed Spain to win the Spanish-American War?

They would have improved Spain's chances, but only if paired with crews and leadership capable of using them effectively.

Three Majestic-class battleships would have made Spain's naval position in 1898 substantially less hopeless. Their modern heavy guns and protection could have forced the United States to approach the campaign differently. The counterfactual still requires crews able to operate the ships effectively. The concern falls on parts of the Spanish officer corps rather than every sailor. Imported hardware could improve combat power only when training, leadership, and institutional culture allowed crews to use it.
