PLATING
DEVELOPABLE SURFACES

PLATING DEVELOPABLE SURFACES

The hull surfaces above and below the Bezier surface at the turn of the chine are developable surfaces. Plating the developable sections of the Bezier 28 is the same as plating a hard chine boat.

Eight to ten foot sheets of thin plywood pre-cut strips, four to six inches in width, are used to scribe full size hull plating patterns.

Using the pre-cut strips overlapping the longitudinal framework, by approximately one inch. Make sure that the template strips are laying flat and even with the framework. Hold the templates in place with tie wires and other clamping devices. Adding corner pieces ties the patterns together. Secure the corner pieces with self-tapping screws.

With the templates secured in place, mark locations for later reference when positioning the actual plating. On the backside of the template, carefully trace - scribe around the perimeter of the framework.

Move the template to a sheet of hull material. The template will lie flat on the sheet material because it is a developable surface. Transfer the template to the hull material along with the reference points. Cut out the hull material.

Align reference marks near the center of the plating along its length to their location on the framework and tack weld here first. With the plating held in position it can now be worked in either direction without excessive force to the framework. Other reference points must fall into place. If the references do not align, look for the reason and correct.
