Called E-Vang, it has just been unveiled by Bamar at MetsTrade in Amsterdam and is the first electronic vang ever manufactured in the world.
E-Vang is a game-changing innovation, a patented product destined to completely change the way sailboats are rigged, which, until now, were forced to use complex hydraulic systems to handle the heaviest rigging. Bamar on the other hand is not new to this principle, suggesting clearly that this is just the latest step in making possible the total elimination of hydraulic systems on board. In fact, all-electric furlers, boom furlers and pad eyes are already available in the product range.
This innovation has many positive aspects that go far beyond the elimination of the hydraulic system itself, such as the ease of installation, which, it seems clear, only requires connection to the on-board power supply.
Safety is another decidedly important factor; E-Vang is in fact equipped with a dynamometric pin that “reads” the external compression loads and causes the vang to automatically adapt to the adjustment requirements. This avoids the possibility of incorrect maneuvers that can cause breakage or overloading.
“It is an epoch-making evolution that E-Vang introduces to the sailing world – Francesco Tamburini tells us – With this product, Bamar’s owners, the Zattini family, wanted to move electrically what until yesterday could only be moved hydraulically. Bamar has been producing innovation for almost 50 years, and it is certainly no coincidence that the world’s largest superyachts, such as Mirabella or Superyacht A, are equipped with our products”.
The new Bamar E-Vang in detail
In order to achieve the highest performance, Bamar starts with whole bars of certified material that are then processed with computerized numerically controlled machines. This process allows the bodies to be made of anodized aluminum alloy, while other components are made of a special steel specifically for their use.
The electric motors that the E-Vang is equipped with rely on planetary gearboxes to be able to achieve maximum efficiency with minimum absorption, as demonstrated by the model presented at MetsTrade, which, despite being sized for 50- to 65-foot boats, has a 600W motor that develops a pulling power of as much as 11,000 kilograms.
Also important is the contribution made by connectivity that allows Bamar’s electronic vang to be connected to the now ubiquitous monitoring systems on board. This way you will have readings of absorption, load cells and end-of-stroke sensors at our fingertips.
Another fundamental adjustment is that relating to the memorization of a fixed boom position; the increasing popularity of sailboats that now have a mainsail furler makes this function indispensable for the proper furling of the sail and averts blockages and sail breakage.
Complementing this outstanding product are the “emergency quick release” functions that allow the vang to be stretched very quickly and the manual operation that, in the event of an electrical blackout, allows the product to be handled with a simple handle or more simply with a battery-powered drill.
