Why we decided against a new diesel.
The prognosis was bad for our engine. First only the cylinder head gasket, then the heat exchanger and the death knell was the heat exchanger housing. This alone should cost around 1900 euros. Even the shipyard wrote to us that we should think about a new engine .... Of course, that meant a new diesel. I asked for a quote for the total cost.
Of course, we also looked at what a new Nanni Diesel with around 15 hp would cost and the shipyard had already given us an approximate budget. Our model Nanni Diesel 2.60HE was of course no longer available and of course we also thought about a new used boat .....
Everyone who knows me knows that I not only drive a Volkswagen eGolf, but that I am fond of new technologies. Where we bought the boat, I had announced to our boat broker that if there were major repairs, the engine would be exchanged for something electric. He then asked to inform him.
Am I particularly aware of the environment or why should it be an electric motor now?
The environmental thought was there, but rather in the background. The main reason is that I hated it in winter storage to always have to change the oil for 5 - 10 engine hours and to replace the impeller for safety reasons. Always winterize the engine and then remove the mess again. Diesel is getting more and more expensive and if the new government cuts the subsidies for diesel and a liter becomes even more expensive then the cost of a diesel engine will increase every year. For the last few years we have been lying in the buoy field in Eckernförde and have only refueled the expensive Ultimate Diesel. The last diesel plague was removed 4 years ago. In winter we always added diesel to the tank to counteract this plague ... Yes, even the expensive diesel now has bio additive. The tank was filled with 5 liter canisters and everyone knows that a drop goes wrong ...
The effort was simply not in proportion to the benefit. We are not the mega sailors, but we enjoy it when the engine is not running.
Furthermore, I didn't want to invest in a technology that has existed for 130 years and is slowly no longer really in demand in the car sector ... How do I know? I've been a car salesman for over 20 years.
What should our new system look like and what range do we expect?
It is a Vetus e-Line 10kW motor. This is operated with 48 volts. There are 2x LiFePO batteries of 200 Ah 48 volts. Because the batteries can be completely discharged, we come to approx. 20 kW / h. Furthermore, we will have a small gasoline generator with 2 kW charging power as a range extender on board.
Depending on the speed, the pure range should be approx. 4 -5 hours or a range of approx. 20 SM at 4.5 Ktn.
But as I know from the experience of my eGolf, it depends on many factors. (Current, wind, wave, temperature and much more.)
We do have a solar cell on board, but it is only supposed to recharge the consumer battery. We don't have a wind generator, but we have sails :)
The weight of the engine / gearbox / tank is removed. For this, the motor comes with its own water cooling (approx. 71 KG) and 2x rechargeable batteries a 75 KG.
In addition there are connection material and charger.
In the next blog entry we will write about the shipyard's offer and everything else ... If you have any questions, just write to me using the contact form or WhatsApp.
Yes, we have a sailing boat and our moogle sails beautifully :)
