Difference between tubes shapes

We produce inflatable tubes with four different shapes. Using of the right shape provide of the best characteristics of your boat.

  • First shape is the most commonly used for motor pontoon boats. Lowered stern of the pontoon gets a course stability to you.
  • Second pontoon shape is better for sailboats or sail catamarans. Another reason of using this shape is longer deck with the same pontoon length. This shape is compromise between first shape and fourth shape.
  • Third shape used rarely for rafting catamarans. 
  • Fourth shape of inflatable tubes lets to make the biggest deck and used for building floating platforms.
