There's a question about this in the FAQ

/u/Vampire_Seraphin gave a good answer.

We don't know. References to the 'sea people' are fleeting and vague. There were enough of them to make Egypt go to war with them, but how big that conflict was is unclear.

There is not much written material about them and even if we found one of their ships we might not know it. To my (limited) knowledge no description of their vessels exists. Added to this, the nature of wrecks in the Med is that they tend t be layered one on top of the other.

tl;dr Past hazy, try again later :)
