Electric Corvetta 24 on the market: the dolce vita of the future.

///

The new electric Corvetta 24 wins everyone over: zero environmental impact and traction aesthetics.

Giorgio Mussini shipyard’s new Corvetta has recently been launched on the market, this time in an electric version. The historic Portofino-based shipyard led by founder Giorgio and his son Gaetano has developed a unit they have been dreaming of for years: a day cruiser with almost zero environmental impact.

electric corvetta 24Precisely during the period of the Covid-19 pandemic, the company pushed the accelerator of creativity and resourcefulness by combining its handcrafted product with electric propulsion.

The propulsion unit was developed and supplied by E4Boat, a network of highly specialized and innovative companies in advanced robotics, electrified and hybrid propulsion and shipbuilding.

The electric Corvetta 24 thus presents itself as an environmentally and financially friendly recreational boat, dedicated to families taking a day trip and slow tourism whether at sea or on the lake.

Corvetta 24 – Design

Featuring elegant and sophisticated lines, the icon of the Giorgio Mussini shipyard that is a symbol of the dolce vita in Portofino is now green. The yard’s first ecological boat astonishes and conquers, taking nothing away from aesthetics and tradition but, on the contrary, adding an important step forward in terms of savings and environmental pollution. Only plus points for this luxurious and exciting craft, almost 8 metres long, characterized by a fibreglass hull, a very deep V-shaped bow and a hull designed to enhance the strengths of the day cruiser: speed, handling and incredible seaworthiness even in very difficult conditions.

All this is combined with precious mahogany or teak finishes that unify the boat and give it that air of craftsmanship and warmth that wood can give.

Electric propulsion

The engine of this corvetta-24-detailCorvetta 24 is the real revolution: permanent magnet electric propulsion generating a minimum power of 30kW with a static power converter and battery modules for a total of 65kWk which translates into an autonomy of no less than 4 hours for the owner.

Not only is the environmental impact reduced to zero, but another important peculiarity comes into play: you will be able to navigate listening only to the sound of the sea.

In fact, the electric engine, unlike the endothermic one, guarantees an unprecedented silence that renews the classic experience at sea aboard a Corvetta and allows the owner to drive and listen only to the music of the sea beating against the hull.

The new electric Corvetta 24 makes a real leap forward for Giorgio Mussini shipyard, which has always been a producer of fine yachts, with tradition in its heart and a mind in the future, as this new model on the market demonstrates.

 

EPropulsion Spirit 1.0 Evo, second year of testing for Selva’s electric outboard

/////

A year has already passed since I wrote about the Epropulsion Spirit 1.0 Evo, the amazing Epropulsion electric outboard that now travels with our lab-boat around Italy, and of which I admit, I am very proud. But here I am again, with the feeling that collecting my memories is very light on me.

Yes, because the satisfactions that it has given us this year too have been many, showing all its usefulness in many situations: what’s more, the fact of combining the silence of the sailing boat, which is clearly unequalled in terms of environmental sustainability, with the total absence of emissions that the use of the Epropulsion Spirit 1.0 Evo electric outboard guarantees for our tender, really appeals to me.

But let us make a brief summary to understand what we are talking about. This outboard, imported in Italy by Selva, is an electric outboard installed on our tender, an indestructible Selva 320 VIB. It is therefore a sort of link between us and the mainland that cannot be allowed to slip, because being halfway between the coast and the boat is never pleasant. Especially in loafers and a shirt before disembarking for dinner. Has this ever happened to you?

Do you remember the features of our Epropulsion electric outboard?

EPropulsion-Spirit-1.0-Evo-electric-ouboardBy dint of using it, I am no longer surprised. After our “1,000-mile cruise in the Tyrrhenian Sea” two years ago, and the more than 900 miles sailed this year, it is now part of our family, but it does surprise those who visit us for the first time and have never seen it before.

Let’s start with the dimensions, smaller than those of a classic tender outboard, and with a weight per single component of less than 12 kg, which makes assembly and disassembly really quick and effortless.  In fact, Epropulsion is installed in stages, first the shaft complete with tiller (11.3 kg) and then the battery (8.7 kg), a system that is light and extremely safe at the same time.

Be careful, however, epropulsiondo not think that this is at the expense of materials. In fact, we have put a lot of strain on it this year, sometimes purposely causing it to take a few too many hits, other times in a less intentional manner, but it has held up to it all.

You know, between filming, drones flying, cameras passing by and a boat to steer, it happens that something has to be ‘thrown in there’ every now and then, if you like.

But that’s the point of our tests, to live as if we were in normalcy and a few jolts are part of the game: in any case, compared to last year, the performance remained the same, still outstanding.

Its display continued to work excellently, showing us, as always, some fundamental data such as the indication of charging volts, maximum voltage and, of course, the residual charge: this engine has a 1276 Wh battery, built according to the latest lithium polymer technology, which takes 8.5 hours to fully charge, although in normal everyday use it takes just over an hour to bring the charge back to full after use.

The EPropulsion electric outboard has a secret

Daydreamer-1000-miles-tyrrhenian-seaBut all this for me, although remarkable, fades into the background in my test because if you remember correctly, the Epropulsion Spirit 1.0 Evo electric outboard has a secret: and what a secret! It recharges itself. Yes, just leave it connected to the tender of the main boat by towing it into the water and it recharges, with minimal impact on sailing speed. In fact, its energy hydrogeneration system, through the flow of water pushing the propeller blades, turns the engine producing energy that recharges the batteries. Game, match, encounter.

This could be enough for me. Silence, because in operation despite the extra year it continues to be very quiet, and free clean energy with the guarantee of never running out of power. Need anything else?

Yes, you might say. epropulsion electric outboardFor example, how much energy does it consume? How far can I really go and at what speed? For all the details of the test I refer you to the table below which, you will notice, is the same as last year’s because the performance has remained unchanged, but to give you a concrete example of its hydrogen-generating capacity, we measured about 1 notch of recharge per hour/hour and a half of sailing at 6 knots. Which basically means that in an entire season we never recharged it using the charger!

During this second year of testing, we have never run out of battery power, despite the fact that very often there were four of us on board, engaged in coastal sailing and the classic comings and goings from boat to shore, even over long distances. Like for example in August when, anchored in Cala Brandinchi, we sailed twice to the Puntaldia marina.

Two hours of sailing, without the slightest problem and, above all, with a good charge still remaining at the end of the operation.

EPropulsion Spirit 1.0 Evo – Conclusions on the second year of testing

EPropulsion Spirit 1.0 Evo is the electric outboard I can no longer do without. Is that enough for you? I’m not exaggerating, because this small engine is not only practical, efficient and quiet, it also marks a turning point. It has something special just in its concept, it makes you realize that it is possible to go to sea using only clean energy, and somehow reconnects me to my favourite element, which on the other hand certainly thanks all those who make such a choice: environmentally friendly and absolutely performing at the same time.
