A portable floatation assembly 10 which selectively elevates a watercraft 20 above a water line. The portable floatation assembly 10 includes a plurality of generally hollow body portions 12 having a plurality of boat reception grooves 32 and a plurality of apertures 30 which selectively couples to a plurality of apertures 26 disposed along the periphery of generally flat base members 14 which contain a central aperture 22. Each generally hollow body member 12 and a unique one of the base members 14 cooperates to form a generally hollow cavity 60 within the cooperatively formed floatation devices 44. Portable floatation assembly 10 further includes a plurality of conduits 16 which are coupled to both a pump 18 and the floatation devices 44 through central aperture 22, effective to displace a volume of air within cavity 60 of floatation devices 44, which is effective to selectively and conveniently elevate a watercraft 20 above a water line.
