The inflatable floatable liferaft (1) further comprises a plurality of non-rigid floatation tubes (3) arranged beneath the non-rigid bottom element (2), the non-rigid bottom element (2) extending in the longitudinal direction and being arranged with an intermediate distance (ID1) between neighbouring non-rigid floatation tubes (3). The present invention further more relates to improved propulsion through the water of such an inflatable liferaft (1).
