Flexible watertanks for fresh water

High resistance flexible water tanks : a reliable, practical and low cost solution to the storage of fresh water on board. They are flexible, light and form-fitting, and can therefore be installed where it would not be possible to install a rigid water tank, due to the shape of the boat or difficult access.
