Believable?

Certainly. My father is in the sea shipping business and for years had a picture of one their vessels on the wall. Once I asked him what was the the deal with that particular picture. He told me that it had went down at sea with all hands lost. An investigation into the disappearance concluded that either a giant wave had lifted the ship in the middle of the bow and it broke in half or that two large waves lifted the ship up at the ends and broke it in half.

Recall a story about the QE2 being hit bow on one night by a wave created by a hurricane hundreds of miles away. I think they said the height was 90 feet, given the fact that it hit the bridge.
