JOLE2 - 2017 42' BRENTA B42
Palma Spain €450,000 EUR
The B42 has been conceived as a 24 hours boat opposed to the 12 hours B38. Similar cockpit spaces as the 38, larger interiors with a separate full standing head and double berth up forward.
All the rest follows the general design philosophy of her predecessor, featuring the controls at the steering systems and, amongst the option the use of composite rigging that improves stability and reduce acceleration improving sailing comfort”

Extra pairs of hands are not required once underway, either, because the boat is set up with push-button controls for hidden hydraulic systems controlling the mainsheet and traveller, boom vang and jib sheet tension. For each of these functions there is a pair of buttons, one to apply tension and the other to release it. All but the jib sheet are positioned on a console at both steering stations, while the jib controls are also within easy reach, so the person at the helm can operate the yacht without any assistance. That could mean solo sailing, but equally it could cover a boatload of family and friends, none of whom know much if anything about sailing.
Controlling the sail trim completely by button-power is a novel experience and a little unnerving when you are trying to remember which one does what (the hydraulics' response to a command is fast enough to allow you to apply a quick touch of trial and error), but this is an aspect of push-button sailing that would soon become second nature when you spend enough time sailing the boat. And "One of the objectives is trying to minimise the time it takes to go sailing," said Lorenzo Argento, co-founder of the Italian company Luca Brenta Yacht Design, while visiting Sydney for the initial sea trials of the two new B42s.
The B-Yacht Mission:
If the B42's Italian dayboat looks and minimalist setup make you think "Wally Yachts", perhaps it will come as no surprise that the B42's designers were involved in the ground breaking early days of those bigger craft.
Brenta Yacht Design specialises in large custom craft for wealthy private owners, like Ghost, a 122ft Wally B, but over the past few years it has gone into production with the B-yacht range of semi-custom performance cruising boats, from 30 to 60ft LOA.
"High performance, easy to use, semi-custom-built boats blending past experience of large custom projects solutions into something new," says the brochure, also defining the mission as: "High weight stability, very generous sail plan, great cockpit comfort and pure sailing pleasure mixed with style."
"We decided to go for a highly ballasted boat and made it as narrow as we could, while still with accommodation and deck space," Argento explains. "We wanted a very balanced hull shape, because it has to be easy to drive and particularly because such a powerful boat will heel considerably, you really like to have a symmetrical hull shape so it doesn't go ‘funny' when it heels over, which is what more dedicated downwind boats do when they sail upwind.
"We don't have people who sit on the rail, so you need high stability if you want sail area and power."
The B42's ratio of sail area to displacement is quoted as 29.9, while the displacement to waterline length figure is 108.
"The boat is not a downwind flyer as such because there is weight there," says Argento. "We feel that people enjoy the upwind bit and if they want to sail downwind and have fun you really need to set a spinnaker and then you need people." [The B42 does have a fractional gennaker, set from a retractable carbon bowsprit pole.]
"But here you have all these races for white sails; this is something that we don't have in Italy. There the racing is always very serious, while here you have the serious side but also a lot of more relaxed [no-extras] racing. I think this boat is perfect for that, or just to cruise around; whatever opportunity you have."
Lorenzo Argento says he and his design partners decided to set up production of the B-yachts only after they unsuccessfully sought a builder. "We were strong believers in this concept but nobody wanted to build these boats, so we found ourselves right in the middle of it.
"We found a builder to make the tooling and 48 boats later... nobody's become rich but it's a very good group of people; we have boats in Long Island [USA], boats here in Australia, in the Med, up in Denmark, Moscow, Stockholm...The owners are very specific in what they want, very demanding but also ready to pick up the technology of this boat."
The hull is infused carbon fibre and E-glass epoxy over a Corecell foam core. "We lay all the dry fibres and then we apply the vacuum bag and by sucking the air out and the epoxy resin in, have control of the amount of resin and the weight differences between the boats is minimised," says Argento. Built in female moulds, the use of the infusion process allows the boats to be spray painted rather than gel coated.
The composites company High Modulus was enlisted in the challenge to maximise the usable interior volume, resulting in a single moulding keel and mast support structure. To achieve this, a finite element model of the hull, deck and internal structure was built and subjected to a variety of loads for detailed analysis.
Ballast is provided by a lead bulb on a fabricated steel blade keel.”
