What Sea tactics in the battle of thermopylae?

Answer:
Themistocles used 300 or so war ships to stop the Persians from coming in through the Artemisum Straight so they couldn't get behind the geek lines. The Persians realized that they could sail along the length of the island to get around the blockade, but Themistocles had anticipated tis and had a blockade there also.
