ONYX Marine | South African Built Catamarans

Introducing the ONYX 10.5

Designed to discover the world

With its reduced length and its 42HP Vetus diesel engine which not only lowers the overall weight, but allows for easier maintenance due to its zero fallible gearboxes, the ONYX 10.5 Catamaran is an easy-to-handle alternative to traditional models. This, coupled with its forward mounted under water computer controlled stabilizing winglets, allow for an unparalleled sea-faring experience.
