Whether or not something floats, has to do with its density, not just its 
mass. Density is the mass to volume ratio. Any substance(immiscible), or 
structure with a density less than that of water, will float in water. 
So a 1000000 boat, with the correct volume, would be able to float.

As to if you can find something weighing 1000000 pounds, which is also 
small enough to fit into the space that 100 pounds of water, is another 
issue, but strictly speaking, it is possible.

I hope this helps

[note added by MadSci Admin: Think about a boat that is shaped
like a flat cookie tin, but very much larger in area.  That
could, in principle, be floated on a large but thin lake.]
