For divers version?
Trovo che sia un idea applicabile ancor di più che sul auto.... Il miglior risultato sarebbe utilizzare l'elettrico su una barca a vela 😉
Non capisco a cosa possa servire, se non in zone altamente ecosensibili, e sempre per navigazione acque interne.
Certo, facciamo TUTTO elettrico. Vi siete chiesto quanto costano le batterie ? NO non credo. Vi siete chiesti quanto successivamente costerà lo smaltimento delle stesse ? Anche qui NON credo. Una batteria per una "macchinetta" costa 3 / 4.ooo Euro, dura circa 3 anni, e lo smaltimento ? beh quello non lo so 🙂 ma sicuramente non poco. Facciamo le dovute proporzioni e...…. credo ci stiano prendendo in giro. ( dimenticavo, ma la ricarica delle batterie mentre viaggiate, la trovate dappertutto ?)
Sul lago...È o.k!...Ma in mare?...Quanto hanno di autonomia?
Nicola Candidi oltre al fatto che è elettrico ha di bello che viaggia su foil, non so se conosci questa tecnica...

Så himla grymt!
Slik som el ferge som brenner - setter det fyr på hele brygge og båtene i en kjede reaksjon. Det blir korte turer, dyr forsikring og farlige forhold for å ferdes på havet spør du meg.
Forsto jeg det rett at båten bruker ca 20 kw per time i 20 knop ?
Hvor stort er batteriet ?
3 fase dobbeltlader ?
Nja det är en så länge inte en smuggler :
Undrar hur framtidens båttävlingar kommer att se ut?
Artig at gammel teknologi fungerer med ny! Rekkevidde?

We are proud to be a nominee for the world's most prestigious boat award - the European Power Boat Award. We are still in the mental transformation from being a funky start-up to a fast moving scale-up with the mission to make all boating emission free. Then it is encouraging to get recognized by the long-timers in the trade. Thank you for the nomination! More here: www.powerboat-award.com/up-to-25-ft ... See MoreSee Less
Given the amount of new technology we put into the products, the customer boats delivered this summer have worked surprisingly well. And there seems to be a strong appetite for more electric foilers on the waters of the world. We have therefore decided to go for a rather fast production ramp up. This includes the ambition to find new automated ways to produce boats. In the light of this, it is an honor to annouce that Frederick van den Oudenalder joins Candela as Production Development Manager. Frederick has a MSc in Aerospace engineering from Delft University of Technology. Since graduation Frederick have spent years with the Boston Consulting Group with focus on Automotive. With his sharp mind and strong drive, I am confident that Frederick will be instrumental when replacing all fossil boats of the world with a more exciting alternative. A warm welcome Frederick! ...

Recently I have gotten quite a few questions around the topic of speed and range of planing electrical boats. Can you build a planing electrical boat with both speed and decent range? Now we don’t build planing boats at Candela so we are no experts in the area (so pls correct me if anything is wrong below). The subject is however well researched, and some quite simple equations have been established. Already back in 1964, Daniel Savitsky published a paper laying out the foundations for calculating the power needed to push a boat forward. Refinements have been done since then but the original article still holds pretty well. And it turns out that you cannot do much to make one planing boat more efficient than the other. You want to have a certain ratio between weight and length and when that is set the only thing to do is to flatten out the hull. Hence, the most efficient planing boat is a dining table turned upside down. But such a vessel would be pretty bad in waves so some V-shape is typically preferable. Therefore, whenever you are told that a certain hull is very efficient, it is fair to assume it is BS. For example, adding steps can give a few %, but only in very high speed. Not pleasure boats. Such steps will only increase the drag at non planing speed which, arguably, is a bad idea for electrical boats especially.
To answer the question on range and speed of electrical boats, let us make an example. Assume a 8m boat, 2400kg plus 200kg passengers, 25kn cruise speed and 40kn top speed, and a V-hull with 18% angle. First step is to calculate the speed/length ratio –as the speed in knots divided by the sqr of the length in feet. That gives us 4,9. Then we need to check a Savitsky table, like depicted, to find the drag to lift ratio. In our case it is 0,18. Since the mass is 2400+200 we get a hull drag of 468kg or 4600N. To this we need to add drag of appendages and air. Savitsky recommends 20%. Then we are at 5520N in total drag. To get the power we multiply with the speed, 12,9 m/s, and get 71kW. To get to the electrical power we need to compensate of losses in propeller, transmission and motor. So we divide the power with 0,6 and get 118kW (the same operation for 40kn would yield 280kW - like a V8 big block). Now it is easy to calculate the range. If you have a 40kWh battery you can run at 25kn in 40/118h = 20min. After 20 min in 25 knots you have reached 8 nautical miles. If you can afford it, the battery size can be increased. If you put in 3 times a Candela battery, i.e. 120kW, the weight would increase with 400kg so you end up with a range of 22kn. With the same huge battery you get 16NM at 40 knots (not accounting for the mass of the electrical version of a V8).
Now if we allow a bit lower speed – say 20 knots, how much batteries do you need to put in to get a decent range of say 50NM (which happens to be the Candela range). Since a light battery is some 5kg/kWh (ours is heavier) it gets harder and harder to get the boat to plane. With an optimistic calculation you end up with a 400kWh battery (10 times Candela, 4 times a large Tesla) and a battery mass of 2 tons. Then, with the wind in the back, you get 50NM of range.
So yes, you can build an electrical boat with both speed and decent range. But if some tanned salesman gives you numbers that do not match with established knowledge, ask for a test protocol and make sure it is not done by Volkswagen 🙂 ... See MoreSee Less
“Ludicrous mode”. To celebrate that I this week, finally, will become the owner of a Tesla, Ludicrous mode feels like the right name for our new approach for handling ludicrous sea. Or at least a bit ludicrous sea. We have put a considerable amount of brain power into getting what may be the best wave handling ever made for a foiling boat. The new mode is achieved with three main changes: First we have redesigned the beam of the forward foil. The new one has a more refined shape to bend and twist in the right fashion under load and it is made in high modulus unidirectional carbon fiber baked in a 20 ton press. Despite being only 20mm thick, it can take 6+6 tons of tip load before collapsing. Secondly we have changed the height control algorithm in a number of ways resulting in a firmer response to waves of the size we want to follow and a lesser response to smaller waves. Third, we have beefed up the power to the hydraulic system allowing for faster foil movements. In the video you get a glimpse of the experience on board. Maybe more interesting is the attached graph showing the height measured from one of the two ultrasonic sensors when running over some larger wakes today. The first wakes are like 1 meter from top to valley and the last is approaching 1,5m. Since the height sensor sits at the boat which partly follows the wave, the real wave height is even higher. With the new Ludicrous mode, the forward foil is moving from some 12 degrees AoA to -4 in less than 400ms. In flat water such a change in wing angle would be painful. First you would feel 1,5 times heavier than you are and a second later you would feel the boat leaving under you with pretty high speed. The reason for this fast and large change in wing angle is that the water molecules move fast up and down in waves. So instead of +/-1,5g in horizontal acceleration, we get +/- 0,2-0,25g i.e. a reasonably smooth ride. And we feel pretty proud! ... See MoreSee Less

It was pretty easy to make a simple calculation and conclude: "they are all wrong. A kid can reduce the energy consumption of a boat with 75% and so kill the global warming impact from all planing water transport.
To move that claim into reality is challenging. We have to make basically everything from scratch. In many areas there is nobody to ask. It has never been done before. Doing something new can feel exciting. But when you fail - despite having pushed your mental focus and cognitive capacity to their limits - the doubt drips in and the mood gets dark.
Then a day like this is helpful. While now focusing hard on getting the first serial boats into water, we continue the R&D efforts where efficiency is one of the focus areas. The 75% efficiency gain has been reached since a while but some new insights into electromechanics and hydrodynamics suggest that there is more to be done. Since six months we have been working on some of the potential gains. For us it meant to move the power consumption down from the current level with 11%. Involving three hydrodynamic changes. Before we were at 16,5kW at 20 knots. The calculations on the new solution said 14,5kW. After many weeks of calculations, computer simulations, CAD drawings, CNC milling, part production and assembly we today went into water. Seeing the 14 kW showing up on the screen was a large relief. A crack in the feeling of doubt. Maybe we are onto something! ... See MoreSee Less

This was a fun day. As written about previously we have changed our model for dealing with waves. And today we got some wind and waves to test in. 30kn wind speed in the gusts and 30kn boat speed against the wind meant more than 100 km/h in apparent wind. And pretty choppy waves. The lift in the wing increases when there is more water above it. And the water molecules make a circular movement in the waves. Both phenomenons cause lateral accelerations at pretty high frequency. Aka a shaky ride (still 10 times better than a planing boat). If not managed. Then it is so cool when the thinking starts to pay off. Wind and waves. Not perfect yet. But decent. ... See MoreSee Less
When starting Candela I had this vision of getting the control system so good that you can take off, turn hard and land with a glass of water not falling. Since a foiling boat is above the shaky water surface it must be possible. Today we made it. Thanks to an extraordinary smart and dedicated team. ... See MoreSee Less
