Hull 4012 Launches At Westport Yachts The latest 130-footer from American builder Westport Yachts has been launched. She now represents the 12th hull in that series to come from the yard. The high performance tri-deck motoryacht will take her owner along at a quick zip thanks to her pair of MTU 12V 4000 M90 marine engines. We can expect a top speed of 24-knots from this proven hull and the particular engine set-up. With full fuel tankage for around 37,500 LTs, it should be enough for coastal runs or island-hopping like in the Caribbean, for example.
