The following video shows of what could possibly be the world?s largest yacht by gross tonnage, the 156 metre project Omar, carrying out maneuvering tests on the North Sea during a recent sea trial. She was launched at L?rssen?s facility in Bremen, Germany in November 2015, of which you can view exclusive SuperYacht Times material here. Her all-cream paint job is not unlike previous L?rssen's we have seen before, but her exterior certainly has a few unique features, such as the large slit in the hull on the upper deck and tapered rectangular shaped windows on main deck.
