Construction and Technology
The eXtreme rib is constructed entirely from prepreg carbon using Formula 1 autoclave technology, resulting in a hull that is as strong as 6mm steel but much lighter. This technology ensures an optimal carbon-epoxy ratio, making the rib very light yet extremely strong.

Performance and Efficiency
The rib's design offers the best strength-to-weight ratio, with a concave hull that provides extra lift and improved maneuverability. It is more efficient, performs better, and has a longer lifespan compared to other ribs. Its lightweight nature allows for easier transportation, making it an ideal tender.
