Inflatable floatable liferaft for marine rescue
First Claim
1. An inflatable floatable liferaft for marine rescue which in its deflated state is capable of being stored in a container on board a ship, vessel or sea installation, and which is inflatable when deployed into the water, the fully inflatable floatable liferaft extending in a longitudinal direction and comprising a non-rigid bottom element having a water side and an air side, wherein the inflatable floatable liferaft further comprises a plurality of non-rigid floatation tubes arranged beneath the non-rigid bottom element, the non-rigid floatation tubes extending in the longitudinal direction and being arranged with an intermediate distance between neighboring non-rigid floatation tubes, and wherein the inflatable floatable liferaft further comprises a propeller-driven propulsion device.

Abstract
The present invention relates to an inflatable floatable liferaft (1) for marine rescue which in its deflated state is capable of being stored in a container on board a ship, vessel or sea installation, and which is inflatable when deployed into the water, the fully inflatable floatable liferaft (1) extending in a longitudinal direction and comprising a non-rigid bottom element (2) having a water side (2a) and an air side (2b). 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 neighboring non-rigid floatation tubes (3). The present invention further more relates to improved propulsion through the water of such an inflatable liferaft (1).
