Maybe it's not the weight of the ship itself, but the amount of weight it can carry.

From the English link;

His model, if one may still call it so, has become a real masterpiece whose structure weighs 70 tons, out of a total weight of 90 tons.

It also mentions;

You've got to think about how to pass under bridges or into tunnels.
The boat is too tall to pass under the bridge. What can you do to lower the boat ?
Easy for François : the radar mast, the funnel and the guardrail of the sun-deck are removable and there is a second hold you can fill with water.
The boat is now 22 tons heavier and thus, lower.

But that may just confuse the issue.
