Multiple challenges
Redefining the concept of a superyacht - the introduction of Dynamic Stability System (DSS), Cl Ellipse rigging from Carbo-Link and spars from Rondal - and suddenly life’s even more full-on
When Baltic Yachts set out to build the world’s first DSS-foiling superyacht for a visionary client, it was a journey into the unknown. DSS had never been used on a yacht of anywhere near this size, or power. With a host of complex engineering challenges to overcome, the owner’s project manager Mattia Belleri of Fluidsailing and Baltic’s project team assembled a world class design loop including Farr Yacht Design, Infiniti Yachts, Lucio Micheletti, Gurit, BAR Technologies, Isotop, North Sails, Rondal and Carbo-Link. The yacht had to be fast and supremely comfortable but also safe, responsive and easy to sail, even with a short-handed crew in the Southern Ocean – but the client’s brief set no defined boundaries. Instead the design team was directed to seriously consider every possible option to achieve the owner’s vision. The resulting yacht, the Baltic 142
Canova, is a genuine game-changer in terms of both performance and comfort. Aptly described in a recent issue of Seahorse as “a full-scale expedition into the future”, it fundamentally redefines the concept of the high-performance sailing superyacht for years to come. Carbo-Link and Rondal were selected to deliver Canova’s full-

carbon rig package on the strength of their previous collaborations, which include iconic superyachts such as Ngoni, Aquarius, Badis and the second-largest yacht built by Baltic to date, the 53.9m (177ft) Pink Gin, whose 68m sloop rig is a full 16m taller than a J Class.
Rondal’s Performance Boom, which enables very precise control of mainsail foot tension in all reef positions as well as at full hoist and can also be “styled to order” to suit a yacht’s overall design scheme, was also a key factor in the company’s selection for this project. In addition to the spars, Rondal also supplied carbon electric captive winches. Canova’s nine-metre transverse sliding DSS foil is designed to achieve a big reduction in heel angle and pitching motion to deliver a more comfortable ride, while effectively reducing the yacht’s displacement by 15 to 20 per cent and boosting its performance. The foil is still being sea-trialed at the time of writing but a case study published by Gurit predicts that it will generate more than 40 tonnes of steady state lift and a peak dynamic lift of well over 60 tonnes.
The brunt of these additional loads are borne by the rig, so Baltic’s project management team, Farr
Above: this is what the future looks like. The Baltic 142 Canova,
pictured here during early sea trials off the coast of Finland, completely redefines the concept of the high-
performance sailing
superyacht. The nine- metre sliding DSS foil can generate a peak dynamic lift of more than 60 tonnes –
most of which is borne by the rig, which had to be engineered and built accordingly
Yacht Design, Infiniti Yachts, North Sails, and Gurit worked closely with Rondal and Carbo-Link to define the load cases and rig layout. To avoid over-specifying rigging components and structures, they had to consider the yacht’s speed-dependent, dynamic righting moment and make an accurate assessment of real-life operational constraints, drawing on their combined experience in engineering grand prix rigs. A further consideration was the owner’s requirement for the yacht to be self-sufficient in remote cruising grounds and for its rig to handle all types of use. Unlike most superyachts, which rely on a large shore crew and spend several days in a marina transitioning the rig between performance and delivery modes, this had to be done on the fly with a short-handed crew, quickly and in any location.
Managing weight was crucial, due to the knock-on effect of any extra weight on the effectiveness of the DSS foil. ‘Working with Farr, North Sails and Baltic Yachts, we presented a wide range of different load cases to determine optimum sailplans and rig setup across numerous modes,’ Rondal’s Friso Hylkema explains, ‘and that in turn defined the rig and rigging loads.’
