Interior design and layout
Despite her classic exterior look, the interior is anything but traditional. ‘We came to a certain styling in the previous boat and thatwas the starting point for the newboat,’ says the lead designer, Michiel de Vos of deVosdeVries design. ‘We elaborated on that and added
lots ofwooden details. All the exterior deck hardware has amatt finish, there’s no polished chrome and it’s similar inside. It’s a very nice boat towalk through because the styling is consistent throughout. There isn’t amajor difference between the guest and crew areas,we havemade it a bit simpler and more hardwearing in the crewarea but themain details are the same.’ When the decisionwasmade to build a smaller composite boat, fitting
Themaster suite is in the bow,with remarkably lownoise levels. Beneath the luxurious finish of its furnishings are lightweight composite structures
everything into theGAwas a challenge for de Vos. ‘Her lengthwas reduced by 17ft and her beamwas narrowed butwe havemanaged to deliver the same functionality,’ he says. Baltic Yachts made a virtual 3Dmodel of the interior,
with virtual reality headsets tomake it easy to visualise and check the size, shape and styling of the various spaces. Significantweight savingsweremade
in the interior, ‘but that’s not down to us,’ de Vos says. ‘We designed it and Balticmade itwork in a lightweightway. They are very good at that. For example In themaster cabin the bed frame is carbonwith awood veneer and the top part of the frame is finishedwith thin, removable leather. The double curved bottompiece is a composite structure.’ For de Vos, the stand-out interior
space is the side-by-side saloon and galley. ‘It’s conceived as a communal area and can be opened upwith a drop- down TV that serves as a partition, or it can be enclosed completely,’ he says. ‘For charter use, you can set up a buffet/ breakfast bar on the central island.’ In a boat designed for long-distance
ForMichiel de Vos,who designed the interior, the stand-out space is the side-by- side lower saloon and galley,which can be open plan or entirely separate
details,’ says Tommy Johansson, Baltic’s projectmanager for Perseverance. ‘The basic idea is to have a solid, stiff structure behind the wood. No shortcuts can be taken so we use top quality prepreg carbon sandwich construction. ‘For thick, solid-looking wood like cap
rails and bulwarks, several layers of teak are glued and bonded onto a lightweight core.Wood selection starts with the procurement and the final selection is down to the sharp eye of the carpenters.’ Quality control is strict and frequent checks aremade. On Perseverance, the deckhouses were finished with 8mmteak veneer.
80 SEAHORSE There isn’t enough freeboard for a
Pink Gin IV-style through-hull door to be practical on Perseverance – you’d have to crawl, rather than walk through it – so there’s a side boarding platforminstead, which folds out fromthe port topside with a boarding ladder that extends up to the deck. A carbon fibre beamruns along the bottomof the aperture in the hull skin tomaintain stiffness and the panel behind the fold-out platformis structural, fixed to the hull skin.
Hybrid propulsion Themain engine is a diesel-electric hybrid with two 129kWdiesel generators
voyaging, itmight seemstrange to have themaster cabin in the bowrather than further aftwhere the boat’smotion in a seawaywill bemore comfortable. However, itmakes a lot of sensewhen
charging a big bank of lithiumion batteries, powering an electricmotor that drives a Hundested controllable pitch propeller on a conventional straight shaft. ‘It’s a 128kw/h system,’ Johansson says. ‘Perseverance can run in silentmode for up to nine hours with everything running atmaximum capacity.’ The 600V systemis stepped up to 750V and distributed via a DC bus. This setup requires a dedicated technical cooling circuit with full dual redundancy built in. ‘Even the hydraulics are high- voltage, with two 50kWpumps the size of a small coffee table,’ Taylor says. ‘So we have 100kWon demand.'
