You can read about the ship’s maiden voyage on pages 24-27. In the commercial market, the rapid pace of digital developments continues. In the summer, you may have seen that, together with global towage operator Svitzer, we successfully demonstrated the world’s first remote control tug. That was a clear indication of just how real the future opportunity is for remote and potentially autonomous operation. We continue to push forward in our ship intelligence innovations, and most recently we’ve been looking at the potential crossover into naval markets. While commercial opportunities are initially focused on remote operations, the interesting message we’re getting from naval customers is that autonomous operation is their priority, so we’re sharing some of our concepts with you in this issue.

The Boat Builder and Manufacturer Collaborative Solution Award for 2016 was presented by IBI magazine and METS exhibition to Azimut Benetti. The jury rewarded “the carbon fibre propeller system Azipull Carbon C65 developed by the Group in collaboration with Rolls-Royce, recognising the system’s innovative nature as well as the advantages it can provide.

Benetti Vivace 125 M/Y Iron Man has been the first yacht to be equipped with this new system.
