The mission was to bring a mainsail furling system already present in maxi yachts and small and medium tonnage boats with proportional weight, price and installation characteristics. The challenge was not easy due to the budget of the latter, certainly lower than the luxurious alms of the sea. All this was possible thanks to the versatility of the composite materials and the design of the mechanical parts that make the system extremely simple and effective.
However, all this would not have been enough, because in addition to needing the best design skills for the realization of what would later be our boom, the true purpose of the system still remains, namely the mainsail!
It is only thanks to the skills and experience of a professional sailmaker that it was possible to create a sail capable of maintaining the same performance as a "classic" mainsail. The merit is that of its fence and its extension.
Moving on to the figures, as mentioned, composite materials can be laminated with different thicknesses and weights, taking as a reference a 40-footer with a boom of 5 meters length. The total weight of the finished structure including mechanics is around 50kg, just over the old boom, without considering all the maneuvers that would be supplanted by the new system.
The price, for a 40-footer, is around 4,500 euros and it is also necessary to add the installation and possible modification of the mainsail, which varies depending on where the boat is and its characteristics.
As for the installation, a first visit on board is necessary to check the measurements before the construction of the boom. After this, the installation requires a day of work and can be done easily from your berth without having to dismast the mast or wing the boat. There is then a outing performed to test the entire system.
