The Naval Architect July 2010 - Optimisation of Superyacht Hulls
James Roy, yacht design director at BMT Nigel Gee and naval architect Rob Sime, draw on their combined superyacht design and commercial vessel experience to explore the practical limitations of optimising superyacht hulls. View »

Boat International 02/07 - ShadowCAT
Two companies in the south of England are sharing their knowledge and experience to create what may become the ideal yacht support vessel. Bjorn Johansson Design, of Bembridge on the Isle of Wight, believes that oweners will gain more freedom by using a support ship whose mission package is superior to that of the mother ship, rather than a converted oil-rig supply craft as is often the case with present day support vessels.

The Yacht Report 108 10/09 - Shadow Yachts
One disctionary definition of the word Shadow is a “constant companion”. It is fairly obvious therefore what a shadow yacht should be: a constant companion to your superyacht. But why would you need such a vessel? View »

Lloyds Register Yacht Focus 09/09 - Company Feature
Founded in 1986, Nigel Gee & Associates began life as a small naval architecture practice based in Southampton. From there our company has developed into a leading independent naval architecture and marine engineering design group. View »

The Yacht Report 114 06/10 - Catamaran Vs Monohull
Two are better than one... Whether that is true for hulls is a matter of a number of complex balance of factors such as use type, speed and the type of conditions anticipated. Here James Roy and Alex Meredith Hardy of BMT Nigel Gee Ltd look back over 20 years of design to try to answer that question. View »

Detailed Design and Engineering
It is our pleasure to present the 2010 edition of the BMT Nigel Gee detailed design and engineering newsletter presenting a summary of the many projects we have been involved with over the last 12 months. We are fortunate to be supporting many shipyards, stylists and naval architects across a wide variety of projects – spanning highly specialised lifeboat tenders, to large superyachts, fast military projects and commercial designs our portfolio is the showcase for our breadth and depth of experience. From concept development to provision of fully integrated shop floor engineering, BMT is working with yards to develop intelligent production designs – practical and production friendly, high quality solutions that can help provide greater efficiency. We deliver fully integrated engineering for steel, lightweight aluminium and advanced composite together with 3D mechanical, systems and outfit design. View »

Composite Engineering
In addition to our design services in naval architecture and marine engineering BMT Nigel Gee provide extensive composite engineering capability based on 23 years experience in the design of performance structures. Arising from our involvement in the engineering of numerous production and custom structures we provide insight into the design of larger yachts, optimising for global strength, weight and production requirements. Our services include management of the design to full Class Approval and provision of shop floor production drawings including design for CE certification. Whether you require a design for low production cost or a performance structure with strict weight constraints we can deliver a reliable solution, independent of material supplier. View »

2009 - RINA Design, Operation and Maintenance of Superyachts
The Shadow Yacht - Toy Box of The Sea Despite the ever increasing size of large yachts, space is always at a premium. The seemingly endless list of equipment that these vessels are required to carry rapidly turns even the largest vessel into a spatial design challenge – from jetskis, speedboats and sports cars to hidden helicopter garages and mini submarines launching beneath the hull. Given that the cost per square foot for this vessel type is at an extreme premium, it is becoming increasingly common for owners to adopt the use of a shadow yacht to carry their ‘toys’ and free-up valuable space on board the mother ship. This paper will discuss the ideal technical requirements for such a vessel and will present a number of possible design solutions. View »

2008 - 20th HISWA Symposium
Longitudinal Vs Transversely Framed Structures For Large Displacement Motor Yachts The selection of a structural framing system in any vessel must be made from a consideration of weight, production matters, suitability to resist global loads and vibration. Vessels can principally be either transversely or longitudinally framed although hybrid systems are also in use. However the choice of which framing system is best can be the cause of considerable debate between designers and builders with the advantages and disadvantages of each system often being debated but rarely quantified. This paper explores the structural design of an 80m displacement motor yacht utilising both transversely and longitudinally framed systems, with the aim of quantifying the weight, structural benefits, and production differences between the two. In the development of the basic structural design, rule minimum local scantlings are considered and then suitably increased to account for practical constraints, production aspects and global loads. Following analysis of the results the Authors have assessed a hybrid framing system which is considered to combine most of the advantages of other systems. View »
