Whatever the type or size of vessel Stone Marine Propulsion can design and manufacture the most efficient propeller for that vessel. This ability is the result of a company that is continually researching how best to incorporate the latest design innovations and manufacturing materials into the propellers it produces.
Our latest design is the NPT propeller; NPT standing for New Profile Technology. This outstanding propeller is fully proven in service on the many new builds it is now propelling and on the ships to which it has been retrofitted which required improvements in their performance and efficiency. More details on the NPT can be found here.
