These rafts consist of two independent inflatable buoyancy tubes placed one on top of the other, they are provided with a single floor and of an inflatable arch tube supporting the canopy.
Thanks to their essential structure and basic equipment, they stand out because of their lightness and reduced bulk and for these reasons they are much appreciated and required by the pleasure boaters.
These rafts may be taken aboard of boats flying the flag of those countries where there is no special national leisure regulation in force.
