hardware needed, not only to handle lines under load, but to also route many of these under deck to give the yacht that stylish clean deck look. There are numerous examples of this innovation aboard Nacira 69, with both custom and production solutions put to use in a clever deck layout that has been also optimised for short-handed sailing. The criteria used in the selections were not only strength for weight, but also durability, versatility and clever design that would minimise friction and chafe wherever possible. These blocks include:
l anodised alloy blocks within the mast to handle halyards and other control lines l 100mm Titanium backstay blocks, three per side, with 7.5 ton working load limits l 120mm gennaker sheet blocks with five-ton working load limits l the downhaul system has 55mm Extreme blocks with five-ton working load limits l wide-sheave ‘tulip’ blocks custom- built to deflect runner tails to the main cockpit winches
Above: the hardware supplied by UBI Maior includes
a new design of headsail furler, custom fairleads and deck cleats, gennaker sheet blocks, 8-ton turning blocks for halyards, a downhaul system, jib sheet inhaul and outhaul, wide-sheave tulip blocks for runners, and a 1:4 hydraulic mainsheet system mounted inside the boom
l at the mast base are 70mm Extreme blocks mounted on soft pads that have eight-ton working loads l on the mainsheet is a hydraulic 1:4 system that is mounted internal to the boom l the jib sheet inhaul and outhaul systems are 55mm Extreme five-ton blocks
To route many of these lines under deck required careful planning of the angles and bury depths so that lines entered and exited their tubes with minimal chafe and friction, assisted by custom blocks installed to handle the turns. Special through-deck plates and line guides were also designed and fabricated to handle these lines, as well as the halyard block mounts at the mast partners. UBI Maior also fashioned the clever retractable bow cleats that fit the aesthetic yet functional profile of the boat. It was here, with the hardware placement, that the team at UBI Maior had to work in close cooperation with Vismara to ensure the layout was perfect during deck construction and there were no delays in the build process, which
took about one year: from January 2018 to January 2019. ‘Nacira 69 has been a particularly challenging project due to the owner’s requirements to have a very complete and versatile boat,’ said Laura Cappelletti of Vismara. ‘The guys at UBI Maior have been really great, helping us going through the different challenges. They supported us all along the way, from the conception to the installation and after-sales service.
‘They have been particularly valuable in anticipating the different issues regarding the hardware and coming up with new and innovative solutions every time. There has been a great collaboration between all the different parties on this project and the team at UBI Maior has been able to take into consideration not only our requirements but also the ones of our other suppliers involved.’ Vismara have been so pleased in working with UBI Maior on this project that they want to try this relationship again on a new Vismara 68 project coming soon.
