Add flotation material to it, like sprayed polyurethane foam.
by making a boat and that way a boat can float anytime in water
Yes, if it makes the water denser, the boat will float easier. For example, it is easier to float in salty water.
anything you want that can float. You can be creative.

The Boat displaces a volume of water and if the weight of the displaced water is less than the weight of the boat, the boat will float.

fowlled it into a sail boat.
make it into shape of a boat
gravity bouyancy
with proper engineering, anything is possible.
Yes the boat will float on liquid soap
