ABSTRACT:
The present invention relates to a floatable vessel lift comprising: at least two pontoon chambers, where each of the at least two pontoon chambers includes a top housing and a base. The pontoon's top housing has an arcuate longitudinal surface and the base side is substantially flat. Support members horizontally join the at least two pontoon chambers to support a vessel during the lifting process. A user varies the submersion of the vessel lift during use by using a single air infusion device that introduces an air flow into the at least two pontoon chambers simultaneously.
