Re: Inboard engines and a changing world

Pursuant to the general nature of the discussion, the boat captured in this video (https://kitchener.ctvnews.ca/video?clipId=1770652) is home built. I met the owner briefly and he told me that he uses 2 (I think) modified Tesla batteries for storage. On a bright sunny day during optimal conditions he said his break-even speed is about 5.2 kts in. When I met him he was just beginning a 250 NM non-stop journey in Georgian Bay and Lake Huron. I guess he made it.

Yes but cars and trucks are much different than boating market. Remember us sailboat owners are a small fraction of a very powerful boating lobby. Large power cruisers that like to plane with >1000hp simply wonít be electric for a long time if ever. Those of us with diesels will be able to fuel up for decades if we want. I see this changeover to electric as a pull not a push

That’s not the point of my post originally at all.

The point is if these are no longer mass market items, they are going to be devastatingly expensive for boaters.

The infrastructure will be gone, the spare parts will be gone. The people that know how to work on them will be gone. It’s going to be a little niche. And it’s going to cost a fortune.

Just like horses.

Itís still coming. Itís gaining momentum.

In 14 years, no more gas or diesel cars, trucks, atvs, motorcycles, or other off road equipment. Boats? Itís coming.

Re: Inboard engines and a changing world

If Elon Musk ever got interested in electric boats, we'd have a workable design in a year.

My money is on the tax system being used to persuade people to change. After all governments don't actually have to do anything new, they just tweak the tax rate as Sean suggested earlier. They don't even have to collect it, the distributers do all the work for them.
So, I presume you know that Bi Oil, Gas, and Coal all get billions of dollars in tax breaks every year and have for over 100 years?

Its here now if you want it. I have a 3 phase 20Hp PMAC motor replacing a Yanmar 30 HP Diesel, 200 AH 48 V DC, and a 4kW 400 V/400 Hz diesel gen set for a complete go anywhere hybrid electric drive. If sailing at or near hull speed I also get regen. If low wind I motor-sail at a few Ah an get about a knot more boat speed plus much better pointing upwind.

No I don't plan to cross oceans, but wouldn't with an ice engine either......spent 6 months at sea once long ago thats enough of that

I knew that already. I agree that it needs to change.

End user taxes
And the renewable industry gets more in tax breaks of all various taxes that are imposed.

For instance an ev car in my state is exempt from sales tax if the price new is under 45k usd new or 35k used. That can be a lot of money our tax rate is 10% +

And, so does ever other industry, green included, that knows how to invest in politician. Historically, bribery, whatever name it goes by, has always been one of the best investment returns available.

Relating to the topic, they use Krautler 15kW pod steerable drives in place of rudders. An interesting performance curve too.

Interesting idea . Worth revisiting in a decade when they expect to have a working prototype.
