> "Small boats" manufactured in industrialized nations have flotation built into the hull. You can get them underwater by knocking out a hole, but they won't go to the bottom without significant damage. Guess it depends upon you definition of "Small Boat". Certainly your standard mono hulled yacht will sink rapidly if you fill it with water (which is purposefully done on occasion, if sailing across an ocean and major damage forces you to abandon ship to another vessel the insurance company may ask you to sink the boat. It's not worth the costs required to salvage and is a danger shipping if left afloat).
