A Belgium-based startup has developed a $1,110 boat called 'Onak' that folds up as a suitcase and unfolds in 10 minutes. Made from the startup's patented Honeycomb Curv Polypropylene material, the boat can stay afloat even when it is entirely flooded with water. The 183-inch long and 33.5-inch wide boat accepts weights between 200-250 kg.
