Offshore powerboat racing

Porta Performance has used 3D Scanning and other advanced technologies to devlop the most advanced race boat designs both hydrodynamically and aerodynamically.

Scott Porta of Porta Performance undertook the challenge to solve the “unsolvable problem” which comes from an offshore racing dynamic. What happens at 100+ MPH when a catamaran converts from a boat to an airplane without wings?

Porta stated, “Here’s the dynamic, the engines are supported by a plane of hard water coming from the hull on the bottom of the gear cases … only until the boat launches and flies. At that point, the engines become a thousand pounds of dead weight, the centre of gravity shifts, the bow elevates, and the rest is history.”

Porta Performance’s scanning partner were able to provide results that did not compromise the physical size of the job, the accuracy over that volume, any line of sight challenges caused by the size and shape of the subject matter and the resolution required to adequately capture the complex surfaces.

With the 3D scanning complete, the case study/proof of concept moves to file assembly, computational fluid dynamics (CFD), 3D printed model and the wind tunnel for design validation prior to creating the tooling and moulds. Upon completion, the intent of the project is to build a full sized, race ready version of the new cat design. Once complete, this boat is slated to compete for a World Championship in the OPA (Offshore Powerboat Association) series in 2020.

Ed Smith, OPA CEO/Principal stated, “In the automotive industry all new cars are tested on the track before production. For us, OPA is proud to be slated as the primary real time test tool for this new technology. With our variety of wind, water and weather conditions, we are the logical choice. We see this as a new marine design solving old school problems.”

The result is simple: Produce vessel designs with both hydrodynamic and aerodynamic integrated technology.
