In between of the steel there are other materials - like air. What counts is the average density of the ship (including empty spaces in between), not the density of its densest component.
The ship has enough gas in it to keep it afloat.
Steel ships float on water because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, causing the ship to float. The shape of the ship also plays a role in its ability to displace water and stay afloat.

A steel ship floats because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, allowing it to stay afloat.
An object will float if it has a density that is less than that of water. Or whatever liquid it is placed on. In the case of a ship, that includes not just the steel, but the entire ship - including air trapped inside the ship.
Steel ships float on water because their shape is designed to displace enough water to create a buoyant force that is greater than the weight of the ship. This buoyant force allows the ship to float despite the steel being denser than water.
A steel ship floats in water because of a principle called buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, allowing it to stay afloat. The shape of the ship's hull also helps distribute the weight evenly, helping it to float.

What matters when you consider the ability of something to float is the mass of water it can displace. This needs to be greater than the mass of the ship. A steel ship is not steel all the way through, a lot of the inside is air, so the effective density is much smaller than if it were all steel.
The steel has a density greater than water; but the ship does not. To calculate density, you divide mass by volume. This includes the mass - and the volume - of any air trapped inside the ship.
The clay boat (like a steel ship) displaces its own weight in the water. So, as long as the sides of the clay boat (or steel ship) is above the water level, it will float. A solid piece of clay will (like a stone) sink immediately.
