Construction of Load Path Sails

This construction starts out with cross cut panels using one of the newer laminates that have been designed just for cross cut sails. The sail is assembled using a laminate that is lighter than is needed for a pure cross cut sail, and then the load path yarns are laminated on top of it to provide the strength needed in different areas of the sail.

The advantages of this type of sail are that it is lighter than a cross cut sail, has continuous yarns running from corner to corner and corner to edge to fully support the membrane and take care of all seam loading, and is much more cost effective than either a triradial or pure string sail. They are slightly heavier than the pure string sails because of the extra layer of Mylar that the load path yarns are laminated with, but are coming in about the same weight as a triradial sail.
