Abstract
A float boom for retaining a floatable material, such as hydrocarbons, floating upon a liquid surface. This float boom consists of separate and sequentially arranged buoyancy chambers having depending channels that are interconnected via a passageway such that an inflating medium is sequentially supplied to the buoyancy chambers. An automatic sealing system blocks access to each buoyancy chamber by closing the depending channel whenever the internal pressure within the channel is less than the external pressure upon the channel.
