Patent ID: 7650845

Claim:
A boat hull protection device comprising: an inflatable element having an inflated state and a deflated state and configured so as to be positionable both inside a hull and outside the hull in the deflated state and positionable entirely outside the hull in the inflated state; an air supply/evacuation conduit connecting said inflatable element to an inflation/deflation circuit, the air supply/evacuation conduit being configured to convey air from the inflation/deflation circuit into the inflatable element so as to inflate the inflatable element to the inflated state, and to convey air out of the inflatable element so as to deflate the inflatable element to the deflated state; and a translational control device connected to said inflatable element by the air supply/evacuation conduit, the translational control device being configured to move the inflatable element in the deflated state between a first position inside the hull and a second position outside the hull by displacing the air supply/evacuation conduit.
