This is classical type, cheap and light catamaran, which, depending on a form and size of tubes, can be used in a various trips. Frame is usually made from young trees on a river bank. However, if weight is not a limiting factor, a metal frame can also be carried and used. Bigger sized catamarans of this type are recently being widely used with motors, particularly in cases to reach highly distant places without cost–effectiveness to rent a helicopter or off–road vehicle. The average weight of tubes of our two–seater catamaran is 9 – 10 kg, four–seater tubes – 12 – 14 kg. Price depends on a tube size.
