Setec provides the yachting world with ‘tailor-made suits’: custom electromechanical systems that include solutions to manage tender and water toy, telescopic masts for navigation lights, and patented, evolving, user-friendly and energy park systems.

Headquartered in Borgaro Torinese, Setec can count on its 50-strong team at a facility spanning 10,000 sq. m (of which 6,500 covered) accommodating the Group’s general management team, engineering, production, central warehouses, general administrative offices, and part of the sales department. This facility is complemented by three additional branches in Milan, Bologna, and Florence; the company’s international presence is ensured by an extensive and organized distribution network.

Setec’s centre of excellence in Nautical Precision Mechanics and applied mechatronics is committed not only to making products but to finding solutions and providing systems.

The Group has an in-house applied mechatronics centre, a sophisticated measuring room (with thermo-hygrometric dust control), and dedicated and certified measuring benches (the 2-axes measuring bench is 7 m long and equipped for centesimal measurements on guides and ballscrews).

THE MAIN PRODUCTS

For over 40 years, Setec has specialised in motion control systems, linear systems, and automation components, designing and manufacturing mechanical jacks, electromechanical linear actuators of various types, linear units, and single/multi-axis servo systems equipped with electronics.

In addition to its catalogue items, Setec designs and manufactures Custom Marine Automation Systems and products for the industrial and automation sector in general, including the boating sector.
It has been supplying 5000/6000 N actuators for small, mainly internal movement systems, such as door-opening mechanisms, lifting televisions, or opening cockpits on fly-bys. However, its quantum leap is in the boating sector – and more specifically in the superyacht sector, which began in 2017 with a very specific product: the Electromast, a telescopic electromechanical mast that hoists the legally required navigation lights on the bow of ships over 50 m long.

This was followed by:

  • the Electrotraslo, a system that in the Aero version combines dinghy handling and hatch-opening in garages;
  • the Electroforce, electrocylinders used to open and close hatches, stern/bow platforms, and balconies available wholly in stainless steel or specific steel-treated paints.

A MAST CUSTOMISABLE FOR INDIVIDUAL INSTALLATIONS

Made of carbon and aluminium, Electromast – a telescopic mast for electromechanically operated bow lights – consists mainly of 3 extension elements and is driven by a self-braking 3-phase electric motor, with a release lever, which can be moved manually in the event of a power failure, and a limit switch unit in the standard version or an encoder and inverter integrated in the motor for the EVO1 version.

It is a product that starts from a standard basis and can be customized for individual installations. It has evolved in recent years, on the one hand to increase strength and durability, and on the other hand to meet customer demands for an increasingly equipped supply.

From the delivery of the first pole in 2017, the company is now delivering the pole with, for example:

  • the upper and intermediate counterflanges to be welded to the hull, customized to the site’s design and often in specific materials;
  • the cable winch that integrates the light supply cable and the relative roller that guides it;
  • the end plate for the flush deck version with the light support integrated in the optics;
  • accessories such as the stay attachment flange to be connected to the second stringer and the relative stays with the hull attachments.

ALTERNATIVE VERSIONS

An Evo 1 version of Electromast has been developed with a motor that is still 3-phase but with motoinverter and the Controlmast PLC control panel conversing with the dashboard. Unlike the standard version, and in addition to the bridge integration, with Evo 1 it is possible to set programmed cycles: for example, you can have it stop in the right position for the stay attachment and then restart it, rather than receive maintenance messages.

The Evo 2 version is ready and tested: instead of a three-phase motor, it has a brushless synchronous permanent-magnet servo motor with an integrated position sensor and brake, with protection class IP65 and with electronic servo drive integrated in the control cabinet. The features are the same as the Evo 1 version but with a brushless motor, so it is smaller, lighter, and more controllable.

HOW DO I MOVE THE TENDER?

Electrotraslo is a system for electromechanical movement of tenders and water toys from the superyacht garage to the water and vice versa. The most popular version, the Aerostraslo, is ceiling-mounted and manages tenders up to about 9 m in length; alternatively, there is a wall-mounted version, Walltraslo, suitable for smaller boats about 5 m long.

Designed according to the different garage sizes, it is suitable for solving problems regarding limited garage height; it is a compact system, custom-made from aluminium and steel; a fixed C-shaped structure is bolted to the ceiling, one or two telescopic arms slide out from the fixed part with a movable hoist inside them. Both the arms and the hoists move on recirculating guides that need the correct sizes to function effectively, thus imposing very tight manufacturing tolerances on the structures. A feature of the Aerostraslo is that in addition to moving the tender, at the same time it also opens the garage door by rotating it upward, simplifying the overall architecture of handling systems in garages.

The first version was complemented by a second one designed with the same guidance systems but different structural elements. The translation systems are also different; instead of rack and pinion, trapezoidal threaded screw and nut marine alloy systems are used, allowing the system to be operated manually from inside the ship in case of electrical problems. It is a cheaper but equally efficient solution.
