Abstract
A reinforcing system for a vessel that can contain water. The system includes a shell for containing water, the shell having one or more jets extending therethrough from an inside of the shell to an outside of the shell, and a structural support layer on an underside of the shell. The structural support layer can include: an inner layer of rigidizer applied to the underside of the shell, a central low density core, and an outer layer of rigidizer applied to the central low-density core. The structural support layer can extend from a bottom side of the underside of the shell, across at least one sidewall of the underside of the shell, and form at least one rib along the sidewall of the underside of the shell.
