Ghost ships in the Ocean

Ghost ships in the seas would be something like sunken ships, but still floating on the water. This could encourage ocean exploration a bit more, and since there are already flying ships in the End, the Minecraft ocean itself could have this type of structure. I also think they could have valuable loot but with a low chance of spawning, referencing the fact that these ships usually carried many valuable items, and since they are still floating, they could be better than sunken ships.
