Hakvoort 45-meter Project 'Adur' Progress Dutch yacht builder Hakvoort Yachts has been working on their 45-meter yacht known under project name 'Adur'. The last time YF wrote an article on this project was back in 2018 and now we can report back to with actual construction progress. The all-aluminium yacht is built on a hull designed by Van Ossanen which features a HULL VANE designed to increase fuel efficiency. This is an appendage we have seen before on one of Heesen's previous builds. The exterior design is by Frank Laupman of Omega Architects.
