A series of industrial design illustrations and patent drawings for a product developed for the maritime shipping market.

Skills: Illustration, Adobe creative cloud

Harbor Telematics (HT), the marketing arm for St James Technologies (SJT), developed a product to measure a barge’s draft.

A barge’s draft is an expression of its storage capacity measured by the amount of water it displaces, quantified by the distance from a measuring line to the surface of the water.

Patents which I illustrated covering this system were applied for and granted by the United States Patent and Trademark Office.
