Indeed yes. Density is defined as mass per unit volume. If all the mass were concentrated in one lump, your boat would no longer float. If the metal walls of the boat were a little thinner, you'd have more boat volume, and lower density.
Density is mass divided by volume: Changing the shape (say by bending it) changes neither.
no, because it is the same throughout, except if the temperature and pressure is changing
No, size doesn't affect an object's shape because it's the same unit and material.
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.

simplee yep
water has the affect on wood that the water is absorbed into the wood sometimes changing the shape or density
Nothing whatsoever.

It doesn't.
It does not matter because the density only matters on the mass and volume.
