In this section we offer foam-filled pontoon-style pedal boats. These boats are designed to keep operating if there is a hole or leak. Foam-filled means there are no air gaps for water to get trapped in the pontoons anywhere. If you want to keep operating because you have sharp objects in your waterway, you're in the right section. Foam still absorbs water slowly over time, so the ultimate as far as the safest no-maintenance boat is a self-bailing deck with sealed and foam-filled pontoons.
