There was a ship made entirely of ice - Apparently.
The SS Baychimo, a Norwegian cargo ship, was built in 1914 and used for Arctic trade. After being abandoned and drifting for decades, it became stuck in the Arctic ice and broke apart. Miraculously, the ship's wooden frame was still intact, but the wooden hull had completely disintegrated, leaving only the metal framework and a few wooden planks. The ship's remains were later found in 1969, still floating in the Arctic ice, a testament to the region's extreme conditions.
