side of the boat. The unique Base Assembly of the Monster Tower includes: a base
fastened to the boat, and a base swivel that allows the base to mount on the top,
outside or angle of the side of the boat. The Heim joint has three purposes. First, it
allows the base to mount if your boat has a slight angle at the mounting areas. Second,
it allows the rear legs to rotate so the tower can fold down for storage. Third, the Heim
joint prevents any of the lateral (side to side) movement of the tower from causing
stress to the boat. You are now an expert on the Parts of the Monster Tower and we will
use the terminology of the Parts List throughout this document. Note that Parts refer to
components of the tower and Items refer to hardware, tools and accessories.
