Abstract: A tool for aligning modular flotation platform sections is lightweight and portable. Its principal components are a fulcrum lever arm, a link rod, and two adapters for gripping coupling means on adjacent flotation platforms. The fulcrum lever arm has a handle portion and a slotted head portion. The link rod is secured at one end in the slotted head portion by means which enable it to move pivotally and translationally in the slots. To the other end of the link rod and the end of the head portion of the fulcrum lever arm are secured the two gripping adapters. They are secured in such a way that they may pivot on the securing means. The adapters may be fabricated to mate with standard coupling means with which standardized flotation platform components are typically equipped.
