Is Theseus' ship still the original one?

Yes According to Baidu Encyclopedia, the material of Theseus' ship has changed, but the design of the ship has not changed. From this point of view, the river problem in Heraclitus has entered the same river twice, and the shape of the river has not changed. The original material composition of theseus ship is only the material reason, while the design and modeling are the formal reasons. As a transport ship, even if all the materials are replaced, it still retains its original transport capacity and similar appearance.
