The skin is supported by the spine at at least three points including an adjustable point. The skin is substantially more flexible than the spine. The spine has a plurality of suspension points that define a longitudinal axis. The plurality of alignment sights are connected to the skin along an axis defining a leveling axis. The leveling axis is substantially parallel to and offset from the longitudinal axis.
