Project update - hull and superstructure joined on Heesen 55m FDHF superyacht

New photos from Heesen Yachts show its new 55m Fast Displacement Hull Form (FDHF) superyacht, project YN 17255, having its hull and superstructure joined together at the Heesen facility in Oss, The Netherlands.

In the picture above, the aluminium superstructure of Heesen's YN 17255 superyacht is lowered onto her steel hull. The first 55m FDHF superyacht from the Dutch builder, Heesen YN 17255 was sold by Heesen in February 2013 in collaboration with Bilderlings Wealth, which both represents the client and manages the project. YN 17255 is the first steel yacht larger than 50 metres LOA with a fast displacement hull – the 65m FDHF superyacht Galactica Star is all-aluminium. Galactica Star will soon be surpassed in the builder's lineup by the new custom Heesen 70m sold last December.

The innovative Fast Displacement Hull Form for the new 55m yacht was developed by Van Oossanen Naval Architects in collaboration with Heesen Yachts in house naval architects while the exterior styling is by Frank Laupman from Omega Architects. The Heesen 55m FDHF superyacht is predicted to reach a top speed of 16.5 knots and achieve a range of 4,5000 nautical miles when cruising at 13 knots.

'This 55m marks the 10th Heesen for which Van Oossanen Naval Architects have provided the naval architecture package, and the fourth based on the successful Fast Displacement Hull Form (FDHF),' says Perry van Oossanen. 'At Van Oossanen Naval Architects we believe the 55m will set a benchmark in terms of efficiency: propelling around 600 tonnes of steel and aluminum at 15 knots with only half of the power installed (1,300kW) is quite remarkable!'

The new yacht will boast extensive outdoor living spaces, ranging from a 110 square metre sun deck to a 70 square metre private owner's terrace. A forward garage will house tenders and toys, to be launched from gull-wing doors on either side. This frees up the lazarette area to be used solely as a beach club, gym and spacious swim platform.

Dutch designer Sinot has signed on to design the interior, which will boast an elegant motif and accommodate 12 guests in six staterooms, including a main deck master, featuring a recessed balcony. Further accommodations are found on the lower deck with a full beam VIP and two twin and two double staterooms.

Heesen will deliver superyacht YN 17255 to her owners in Summer 2015 after intensive sea trials in the North Sea.
