The primary impression on stepping aboard for our Silent 60 sea trial is how mild, ethereal and spacious the whole lot feels – extra such as you’ve entered a big, luxe seaside home slightly than boarded a vessel that’s going to take you out alongside the water.
The wrap round home windows present the panoramic view, and with the fore and aft sliding doorways open a delicate breeze drifts by way of the primary deck salon, finishing the phantasm that you’re solely out within the open air.
The temperature right here in Fort Lauderdale is within the low 80s F (mid 20s C) and the clear blue sky is speckled with the sorts of clouds that impressed Joni Mitchell’s ‘ice cream castles within the air’ lyric.
The Silent 60 we shall be taking out right now is their not too long ago launched entrance exit mannequin. This vessel was constructed within the firm’s Thailand shipyard (they also have facilities in Austria, Italy and Turkey) and can shortly be making her approach up the US coastal waterways to her new dwelling and proprietor within the New England space.
Captain Kyle Miller shall be piloting that journey, however right now he takes 12 of us out for a cruise on the Intracoastal Waterway, accompanied by Silent Yachts in-house Designer Juliana Miguel and US Gross sales Director Philip Bell. They’re all keen to point out off what the Silent 60 can do. And we’re all wanting to expertise it.
Photo voltaic electrical yachts pioneer
Silent Yachts is a pioneer in photo voltaic electrical boating. Based in 2004 by professional sailors and avid environmentalists Heike and Michael Köhler, they spent the following 5 years measuring the manufacturing and consumption of power on each journey – lengthy or quick – figuring out how one can mix electrical propulsion with a completely onboard power provide.
After 15,000 nautical miles of analysis they have been able to construct their first self-sufficient and purely photo voltaic powered bluewater catamaran, the Solarwave 46. Then it was time to check that boat for an additional 5 years, on the rivers of Europe, the Black Sea, Aegean and legendary Mediterranean.
Subsequent got here the problem of how one can add and repair the power load required to host 8 passengers with a water maker, electrically ready meals and different facilities like ship-wide heating and cooling.
By 2016 they have been prepared with the Silent 64, the primary serial manufacturing photo voltaic powered yacht on this planet, and in 2018 the 64 crossed the Atlantic Ocean, travelling from Cap Verde to Barbados in 16 days, with a mean velocity of 6 knots.
The Silent 60 line we’re on right now was launched in 2021 with extra highly effective electrical motors, bigger battery banks and the newest photo voltaic panel expertise. She has gained quite a few awards, together with the 2021 German Design Awards and Gustave Trouvé Awards for Excellence in Electric Boats and Boating.
Twin 250 kW motors, 225 kWh battery storage
Captain Miller has helmed a couple of iterations of Silent-Yachts catamarans, the primary in early 2019 when he sailed a Silent 64 from the Bahamas to Florida. His on-the-water expertise helps information the corporate’s design advances.
“Each boat since that 64, you possibly can simply see and really feel the enhancements” he says. “In my view that is the most effective boat Silent-Yachts has constructed, definitely the most effective I’ve captained.”
The massive change, he says, is the upper energy motors. The Silent 60 is offered with quite a lot of motor and battery programs, right now’s boat has twin 250kW motors (≈340 HP every) and lithium ion battery packs with a mixed 225 kiloWatt hours of electrical energy storage.
This offers the Silent 60 the power to up its cruise velocity from 6 to eight knots, however Kyle says the rise in energy can also be appreciated when docking or in tight quarters.
“You might have much more management” he says, proving his level by easing off a aspect slip within the slender canal the place the boat is moored, then executing a good flip to get us out on to the Intracoastal.
After a couple of minutes of cruising alongside the primary waterway, it’s obvious that Silent Yachts lives as much as its identify. At a leisurely 4 knots, you possibly can barely discover a slight hum, after which solely when listening intently. That hum instantly stops although – however with no change within the boat’s velocity.
“That was the air conditioner” says Miller, “I turned off the blowers for the salon.” Apparently that refreshing breeze we seen earlier coming from the sliding door on the bow finish of the salon has a really sensible objective.
Air con is among the main energy hundreds on any yacht. The Köhlers knew that from their years and miles of analysis and have made certain that the items on all Silent-Yachts fashions are among the many best anyplace.
Nonetheless, they’ll draw as a lot as 8 kiloWatts of energy when working at full blast, and we are able to see from the simply understood display of the power displays that’s about the identical draw because the motors at our present velocity.
The corporate’s first photo voltaic electrical catamarans didn’t have the entrance exit possibility, but it surely’s cooling impact is an enormous bonus.“If you may get snug with out the air-con on, you possibly can successfully double your vary.” says Miller.
The opposite advantage of the entrance exit is with the ability to simply entry the sundecks at both finish of the spacious salon. Each are excellent locations to take pleasure in a cool drink of your alternative, and have a quiet dialog with out the rumble of motors beneath you.
Catamaran platform makes for big open house

The impression of airiness we received on first stepping aboard solely will get stronger as we spend extra time on the Silent 60. The catamaran format supplies an enormous platform for the entire dwelling and enjoyable areas, and even with 12 on board you possibly can simply discover your personal little spot to curve up with a guide or do no matter else you prefer to with out working into the opposite visitors.
The entrance lounge off the primary salon has an L-shaped seating space on one aspect of the entrance exit door, a double dimension day mattress on the opposite and a big deck with space for storing and hatches.
The strict lounge is a multipurpose space the place 6 visitors may sprawl out on cushions or all might be accommodated for a meal on the eating desk.
Stairways on both aspect lead right down to swimming platforms and between them is the hydraulic platform/raise that may carry a 4 metre (13 ft) tender/dinghy or jetski (ideally electrical). The draft of the 60 is below 1 metre (39”) so it might probably entry even the shallowest swimming areas and bays.
There may be one other sizeable lounge space on the flybridge (to benefit from the ocean breeze in all its glory) the place 8 individuals can comfortably sit and chat and in the event you actually need to be alone, there are at all times the cabins within the decrease deck and pontoons. There are 4 in complete, all with ensuite loos: the total width grasp (20 Sq m) VIP cabin, and a couple of beneficiant visitor cabins, 1 with a double mattress, the opposite with 2 singles.
The air-con followers are on after we go within the sleeping areas, however it's putting how quiet the whole lot is contemplating the motors are actually a few meters/yards away. Onerous to think about they might be this serene if it have been 250 horsepower fossil gas motors that shut.
The primary salon is the place the place you possibly can actually really feel the distinction a catamaran makes to consolation and house. It's 50 sq. metres (550 sq ft), however figures don’t do an excellent job of conveying how huge it feels, particularly with the wraparound glass. The minimalist design and lightweight colors additionally contribute to the open air atmosphere.
Inexperienced philosophy extends to supplies
The cockpit is on the bow, with lounging house on one aspect, the eating space on the opposite and the open kitchen galley space.
The Silent 60 is clearly meant for entertaining and travelling with family and friends, so the kitchen/galley and the way it suits into the move of life on the water is crucial to that have.
The galley space is in a U-shape, the underside of the U going through the aspect of the vessel and the counters – one with cooking home equipment and the opposite for the sink – are islands the place the ‘chef’ can simply chat with anybody both in the primary salon or the outside stern lounge. Designer Juliana Miguel says there may be an fascinating distinction between the corporate’s European and American shoppers.
The Europeans choose the ‘cooking’ island to face the inside salon whereas these within the US nearly invariably select the alternative to allow them to chat with visitors within the open air lounge.
“The counters are precisely the identical,“ she says “they're simply switched for what the shopper prefers.” She’s joyful to configure the arrange both approach, even happier to seek the advice of with shoppers on the supplies used all through the boat inside.
Juliana began with Silent Yachts in 2021, coming from a background typically inside design with a further diploma in yacht design. She beforehand labored with giant cruise corporations and is delighted to now be with an organization that focuses on decreasing the environmental impression of the entire vessel. That features the supplies all through the inside.
“There are some unbelievable merchandise on the market, with an increasing number of corporations offering data on the impression of the entire manufacturing cycle.” she says. “I'm delighted – the shoppers are delighted, too – after we discover the material, or desk prime or different materials that has the precise feel and appear they need and can also be as environmentally pleasant as doable.”
Photo voltaic panels can generate 17 kWp
Except for the oodles of house for dwelling quarters a catamaran permits, the hull format additionally supplies a technical benefit for electrical boats: oodles of floor space to put photo voltaic panels.
There are 42 panels on the roof and foredeck of the Silent 60, with a complete electrical energy era score of 17kWp: kiloWatts peak, which means 17 kiloWatts per hour could be generated below excellent circumstances.
As we speak’s circumstances are fairly near excellent – it’s a transparent day and we're out cruising within the afternoon when the solar is shining most straight on the panels.
All which means, at the same time as we cruise alongside, the boat is definitely producing extra electrical energy than we're utilizing and placing the excess into the battery. The motors are utilizing 8-10 kW, and the air conditioner and different lodge load about 5 or 5 kW. It’s like filling up your boat with gas at the same time as you cruise.
Not each afternoon is as excellent as this, however alternatively, the photo voltaic panels are producing electrical energy on a regular basis the boat is within the solar, whether or not it's transferring or moored. It will also be charged with shore energy, and the battery’s 225 kiloWatt hours of electrical energy can be found every time calls for requires.
We get an surprising style of how precisely that works when one other boat comes unexpectedly shut within the tight and sometimes crowded waters of the intracoastal. Our blissful quiet was instantly interrupted by the rumble and vibrations of the motors being thrust into reverse – exhausting.
The moment torque and response of the 250kW motors got here in very helpful within the scenario, and whereas it's exhausting to gauge, I'd estimate that we have been in a position to come to an entire cease inside lower than the size of the catamaran.
Examined on the open seas
The episode did interrupt our tranquil cruise, but it surely additionally served as a reminder that water and climate circumstances don’t at all times cooperate. Which brings us to a different advantage of catamarans – stability.
One of many visitors requested how the Silent 60 performs in tough waters. “We have been in one of many first 60s, towing a 24 foot dinghy behind us, going from Barcelona to Majorca,” Kyle tells us. “It could have been a couple of 14 hour journey – till the mistral winds blew in from Africa and we have been in the midst of 16 foot (5 metre) seas.
“There’s no hiding in 16 foot seas,” he stated “and sitting on the ground again there you noticed the tender go up after which drop down under the horizon, and we have been like…OK…it is a fairly good sea trial, good take a look at!”
“We ended up altering our path simply to ensure we didn’t lose the tender, and the run became 28 hours as an alternative of 14, however on the finish of the day it was all good, no harm to both vessel and all able to get again on the market the following day.”
One hopes that one isn’t going to run into these sorts of circumstances frequently, however surprising circumstances are one of many causes the photo voltaic electrical catamaran has a diesel generator on board and might carry 1,000 litres of gas.
The gas is used to cost the battery, the motors proceed to function all-electric. The back-up is there for instances when you'll want energy both for brief time period spurts or for sustaining increased speeds over a protracted interval. It's also helpful for prolonged open water cruising when the solar is probably not cooperating or you might need to go at excessive velocity to get out to a vacation spot or again to shore.
Kyle says it's extremely unlikely he'll use any diesel in any respect on the journey as much as New England, and the brand new proprietor is trying to make use of the boat for relaxed daytime and in a single day cruises with household and pals pretty near the coast, not for going out on excessive velocity runs.
The peace and quiet of the Silent 60 doesn’t come low cost, with a place to begin of about $3 million (US) with none customization. Many of the new house owners – and there are twenty Silent 60s being constructed proper now – clearly suppose that's good worth for the serenity of the on-water expertise in addition to figuring out they're treating themselves and their pals to a luxurious expertise with out rising their carbon footprint. The value of diesel can also be making photo voltaic electrical propulsion enticing to an entire new sort of shopper.

Silent 60 sea trial makes use of 7kWh
As we arrive again at our slip and softly sidle into place surrounded by dozens of fossil gas yachts of comparable size, one can’t assist however mirror on the distinction in consumption. Earlier than we disembark, I ask concerning the closing tally on power utilization. We began out with a full battery – 207 kWh – and arrived again with 200 kWh.
Not unhealthy for a one and a half hour cruise on a spacious catamaran with all of the facilities one may need, a large predominant salon, solar decks galore and all of the whereas with the ability to respect the journey with none rumbling motors or exhaust fumes.
I take one look again on the Silent 60 earlier than I am going and there she is, sitting within the solar, her photo voltaic panels silently recharging her batteries – at no cost – and getting set for an additional nice day tomorrow.
Thrilling issues are occurring daily in electrical boats and boating.
