Three to four months of preparation go into transporting the boats to the sea because of the large number of permits and certificates required.
Arthur Brouwer, the CEO of Heesen, said: “Building large and complex superyachts is exciting, both from an engineering and construction perspective.
“We also managed to keep the construction of Project Cosmos, now known as MY Galactica, on schedule – which was no mean feat.
“Cosmos is the ultimate expression of our ability to build daring projects that stretch the imagination of its engineers and craftspeople.”
