This all depends on buoyancy of the liquid the boat is in, and the density (therefore the mass and volume) of the concrete boat.

Why does concrete float?
it displaces water
Why stone sink into water?
A stone is more dense and heavier than water, so it sinks. If you were to hollow out the top of the stone into a shape like a bowl, it would then be mostly filled with air, and might float. That is the same idea as with boats - even steel boats float if they are hollowed out to where they are light enough. I have even seen competitions to see who can build the best concrete boat.
Why do boats float and ships sink?
Provided the boats and the ships displace their weight in water without the water coming inboard, they will float and not sink. A boat made of wood is likely to float even when full of water because wood tends to float. It is all to do with displacement and freeboard.
Would Blocks sink or float?
Wooden blocks will (usually) float. Concrete blocks sink.
Will concrete sink in water?
If the weight of the object is greater than that of an equal volume of water, it'll sink. People build boats out of concrete - it's a common assignment in civil engineering classes. If the boat will displace 1000 gallons of water but it weighs less than 8000 pounds...it'll float.
Can a plactic boat float?

What makes boats float on water?
Bouyancy is what makes a boat float
Why are boats hollow?
So that they float.
What things won't float?
Every rock (minding bedrock) bricks, ships or boats if they get water in them, concrete, cement, televisions, stereos, ....etc. Things more dense that water
