The story of a refit on the Lady Jade, now a 40-meter yacht
The complex design also allowed the yacht to be lengthened by 20% at the Turkish shipyard Alia Yachts; particular attention was paid to the structural calculations for the modifications to the steel hull and the aluminium superstructure.
Lady Jade is a superyacht built by the Brazilian shipyard Inace in 2008. Originally a 30-meter waterline length, she underwent a complex refit in 2017 to lengthen her hull by approximately 6 meters and install a structural bimini on her upper deck. After a major refit, she was returned to her owner by the Lusben shipyard.
Francesco Rogantin's Names (Naval Architecture & Marine Engineering Studio) followed all phases of Lady Jade's renovation, starting from the conception, moving on to the design and finally to the construction at the Turkish shipyard Alia Yachts.
"The owner had fallen in love with the classic lines of this yacht," explains Francesco Rogantin, "but he was also drawn to a sistership that had had its stern lengthened. This was therefore the initial input we, like other design firms, received. When the choice fell on Names, we immediately began the detailed design of the structures and naval architecture, which needed to be thoroughly revised to meet the requirements: a lengthening of a full six meters with a complete overhaul of both the hull, including a recalculation of weight distribution, and a verification of the strength of the existing structure to withstand such a radical renovation."
This work was made possible thanks in part to the experience Names has acquired in naval architecture, with in-depth knowledge of hydrodynamics, materials, and various propulsion systems. Its team of experts guaranteed full support throughout every phase of the project, from feasibility analysis to detailed weight, stability, and performance forecasts prior to the final design.
Using CFD (Computational Fluid Dynamics) techniques, a method that uses numerical analysis and algorithms to analyze fluid dynamics problems, comparative tests were performed before starting any intervention – the study informs – only in this way could they be certain that the six-meter lengthening, which would have brought the waterline length from 30 to 36 meters, would not affect seakeeping, therefore by verifying the wave field and the resistance and trim values following the modification.
“The lengthening of the stern was functional to a complete redesign of the vessel, also in terms of usability, in accordance with a very specific desire of the owner who wanted it more open towards the sea, but also with a revision of the lower deck where, in addition to technical spaces, a sauna was created” recalls Francesco Rogantin.
Designer Stefano Pastrovich has also overhauled the yacht's three decks, increasing the covered space, particularly by adding a structural bimini top on the upper deck. The interiors have also been renovated, offering six cabins for six couples, including the owner, and four crew cabins for the captain and five sailors.
