Heesen is delighted to report that the construction of their largest steel motoryacht, the 67-metre Project Sparta, continues to proceed on schedule. On April 29, the completed hull was turned right way up to allow engineering fit-out to begin.
Konstantin Kolpakov of Arcon Yachts said: “The combination of Heesen’s excellent Dutch quality with the beauty of the lines from Winch Design, and our own expertise, will deliver a magnificent result.”
With both her exterior and interior by Winch, Project Sparta is a wonderful example of how experienced clients in partnership with leading designers can work alongside Heesen’s 1,000-strong team of dedicated specialists to create a truly world-class custom yacht.
Sparta’s quietly assertive yet sporty profile incorporates a raised pilot-house, with an elegantly understated reverse sheer connecting a powerful bow and a stepped aft deck area with a 6.5-metre infinity pool. Indoor and outdoor spaces connect harmoniously and create a perfect haven for family life and relaxation.

“The turning of the hull marks a special moment in the construction of this exceptional project, and brings with it a great sense of pride and accomplishment to all involved,” said Jim Dixon, director of Yachts & Aviation at Winch. “It is always a pleasure to watch our designs turn into reality, and we look forward to following the next stage of her development in Heesen’s capable hands.”
With a huge internal volume of approximately 1,200 GT, Project Sparta is the world’s largest steel Fast Displacement Hull Form motoryacht currently in build.
Given her plumb bow design, hull designers Van Oossanen and Heesen’s own naval architects researched numerous spray rail options to keep the deck dry in all conditions, with computational fluid dynamics simulations complemented by tank testing at the Wolfson Unit in Southampton.
