Abstract

A sail includes at least two layers of durable sailcloth material, a scrim of load bearing yarns arranged in predetermined load path orientations, and at least one heat-activated adhesive layer securing the layers of material to the scrim, such that the scrim is positioned between the layers of material. An opaque layer may be included between the two outer layers of material to prevent the passage of light through the sail. Alternatively, the adhesive layer or layers may be dyed or otherwise colored to effectuate an opaque layer. The sail is preferably manufactured using a high temperature, vacuum lamination process to mitigate the quantity of voids between the layers of material and to transfer visible content from one or more image transfer mediums to the outside surface(s) of the layer(s) of material using dye sublimation to provide durable imaging. After lamination, the image transfer medium or media may be discarded.
