All Hobies come with floatation inside the hull and will not sink unless you have negative buoyancy attached in excess of the weight of the hull plus 10%. It's a European spec I don't know if any other kayak companies comply with and I believe is also one of the reasons Hobies were the only NMMA certified kayak on the market.
All that being said, still better off checking all your stuff frequently and having a hand or electric pump on board cause you aren't gonna be staying upright or moving along too easy with your boat flooded if you don't secure you hatches/plug.
