Heesen has delivered YN 18750 Masa, formerly known as Project Aster.
The 5000 aluminum class, 164-foot (50m) semi-displacement motor yacht was launched in April.
Frank Laupman of Omega Architects designed the exterior, while Cristiano Gatto designed the interior.
During a two-day sea trial in the North Sea, Masa’s two MTU 16V 4000 diesel engines exceeded the contractual speed of 23 knots, according to Heesen. Interior volume is below 500 GT.
