On October 28, Persico Marine (Nembro, Bergamo, Italy), made up of a team of experienced builders and engineers of carbon fiber racing yachts, from coastal / offshore yacht designer Carkeek Design Partners (Palma de Mallorca, Spain) and Pininfarina Nautical (Turin, Italy) revealed the concept of its Persico F70 “hyperbateau” project.
The Persico F70 is a super-fast, lightweight, sheet-assisted carbon fiber composite day racer and runner designed to deliver unparalleled performance with style and comfort. Said to incorporate the latest research and development (R&D) and cutting edge technology, the F70 series is Carkeek’s answer for a dual purpose foil yacht, with the aim of offering owners a smooth transition from sailing to day and regatta racing modes.
âSeventy feet was deliberately chosen as the best midrange starting size to provide an optimal overall solution,â Carkeek explained in a previous announcement regarding the project. âIt takes into account low crewing requirements, dual use, racing and lifestyle demands, while keeping an eye on costs and the bigger picture. “
Pininfarina Nautical has collaborated with Carkeek Design Partners on the exterior and interior design and all composite components will be built in-house at the Persico Marine shipyard, incorporating the use of robotic technology recently developed by the company.
âThe F70 will be an unprecedented boat,â says Shawn Carkeek, chief designer of Carkeek Design Partners. “The foils, derived from those of IMOCA60 [monohull sailing yacht], will be helped by elevators on the rudder, just like those of the AC75 [racing yachts]. This way the boat can reach full flight mode with only 10 knots of wind, without resting on the leeward side of the hull. In addition, the foils will be fully retractable to allow the F70 to dock easily, and the project will rely on the same CFD and VPP software used on both the IMOCAs and the AC75s.
To make this a reality, an aerodynamic study was previously carried out to guarantee exceptional performance, drawing on the hydrodynamic expertise of Carkeek and the know-how of Pininfarina Nautical developed over the last 50 years on its wind tunnel.
Materials & Processes: Composite fibers and resins
Compared to traditional materials like steel, aluminum, iron and titanium, composites are still maturing and only now are they better understood by design and manufacturing engineers. However, the physical properties of composites, combined with unbeatable lightness, make them undeniably attractive.
Materials & Processes: Fibers for composites
The structural properties of composite materials come mainly from the reinforcement of fibers. The types of fibers, their manufacture, uses and end market applications in which they find the most use are described.
