Van Oossanen is set to present three new hull concepts at the Monaco Yacht Show 2016. The new designs share an increased interior space, a far greater exterior area, high-speed potential and shallow draft, the Dutch naval architecture firm explains.

Van Oossanen, the Dutch naval architecture firm in the Netherlands, has released three new hull concepts: Fast Displacement XL, Gran Displacement and Be-3.

All these designs, the company explains, share an increased interior space, a far greater exterior area, high-speed potential and shallow draft.

These concepts follow on from the firm’s patented Fast Displacement Hull Form (FDHF) that has been the foundation of many yacht designs including Heesen’s 65m Galactica Star and 70m Galactica Super Nova.

The Beach series by Jetten Shipyard, a line of motoryachts ranging from 13m-22m (45ft-75ft), has also been developed based on its FDHF.

Fast Displacement XL

The patent-pending Fast Displacement XL aims to maximise the length of the FDHF concept without increasing the gross tonnage.

“The main advantage of the Fast Displacement XL is the possibility to create the longest yachts ever at the traditional gross tonnage boundaries of 200, 300, and especially 500gt,” the company explains in a statement.

“It is now possible to design a 60m-plus (200ft), three-deck yacht, with a maximum speed of 30ks staying below a 7ft draft, while staying below 500gt. This avoids the additional crew, complexity and especially costs that come with yachts of over 500gt,” reads the statement.

Also developed are designs of 199gt at about 35m in length and 299gt of over 45m in length.

Van Oossanen has also revealed that discussions with various shipyards, as well as private clients, are far advanced.

Gran Displacement

Commenting on the Gran Displacement hull form, Van Oossanen says that it allows 30% to 40% more interior volume within the same length than a traditional yacht.

The idea behind the Gran Displacement concept was to create maximum interior volume within a given length, without sacrificing comfort, high speed potential or the other performance characteristics of the FDHF.

This hull form is optionally equipped with the newly developed Assisted Hull Vane, a pair of hydrofoils positioned fore and aft under the hull that will create hydrodynamic lift and thereby reduce the required ship’s power and increase comfort by dampening up to 40% of the hull’s vertical accelerations.


The Be-3 is a tri-hulled yacht design that features a FDHF hull with two additional outriggers.

Opposite to other recent multihull motoryachts, Van Oossanen used the extra beam provided by the outriggers to place its Hull Vane, allowing the main deck to be extended over the full beam.

Managing directors Perry van Oossanen and Niels Moerke will introduce these new hull concepts to the global yachting industry at the Monaco Yacht Show 2016.
