Big News from Yeargin?

1. You are assuming CC financed this entire project (wrong)
2. You are assuming it costs tons (wrong)
3. You are forgetting boats have been expensive far prior to this electric boat concept (true)

If they don't look towards the future, they will get passed by. I prefer to hang my hat with a company that is constantly pushing the envelope. It is quite short sighted to think that every project a company works on is going to fit every person. This was a technical exercise performed by TWO companies. I'd call it a success for what they were trying to accomplish.

WOW.
What boats are those?

I think I saw a Mastercraft logo on the corner of the second video.

Also, as to how the prius and the volt use their motors to power, yes, both have planetary gearsets and even the volt can be propelled by gasoline motor, even though GM doesn't say it can be technically motivated directly by the gas motor.

Motor trend had a great article on how the planetary gearsets worked on both the prius and the volt about 2 months ago. Good reading too.

Now as to the origin of the SN-E's motors, I can safely say that these motors were drop in converted to marine use, and not designed originally for powering a boat. I say kudos to marinizing them though.

BTW, I couldn't get the "gunnel" on an A22 that I messed around with at the local boat show to deflect like you supposedly did. I could generate some slight movement if I leaned and pushed very very had right on the center of the side of the hull in the middle of the boat, but I was also able to do that with the other boats at the show.

You want to see some "deflection" check out these videos I that I saw.

WOW.

Bad.

and putting conformal coating on is hard, little if anything would be requried.

Again, get rid of that gearbox, please. Sounds like you didn't really agree with the motor selection either.

sorry not going to happen not possible to eliminate the gearbox or the need for a gear set

Never-mind, on second thought the better choice would be to abandon the whole project.

Even if the battery life could be increased 3x it is still a failure by my metrics.

how is it a failure? there are batteries out there that do have 3x the Amp/hours, the boat is green and doesn't polute the water or air and with wind, or nuclear power to charge the pack it's a win win for everyone, cost would be a wash with volume, as that is the issue now driving the price up, it's not an issue to have 220V at the dock and most marina's all ready have it if they rent slips for larger boats, yea you might have to add power at your own personal dock if you live on the water but that is a small price to pay for being green minded.

[Mikeski]

A slalom set on a private lake is less than 5 minutes of operation under load. According to the movie you get 4 sets out of a 3-4 hour charge. So the duty cycle ratio of run to charge is only about 8%. Where I boat I could not even get to the slalom course before the batteries would be dead. In my experience when I was running a private lake the boat would need to run about 10x that time or have a much shorter charge time. If you could get the charge to run ratio down to 3:1 or less you might have a useful boat. Forget ever using it in a tournament. Competitive skier want to practice behind what they will have in a tournament. So in my book there is zero application for this boat and therefore it is a failure.

I guess it is a nice marketing peice? We're still talking about it here.

And this is what I've been saying the whole time - see 1st page of this thread, 4th post. CC has the marketing and hype figured out big time!

Don't get me wrong... I love 'em, I'm just saying.

For almost 20 years I have been doing significant energy efficiency and solar power projects that have a positive impact lowering the carbon footprint of my customers. The idea that this boat has anything more than a microscopic impact an anybody's carbon footprint is insulting to my industry.

[gride]

The only way it's green is if it's charged by wind and or solar, or water I suppose. I think a good step would be to use recycled materials for the build and go from there.

ohh sorry you must be god of the green world, but realy is reducing CO emissions really microscopic? that's like saying solar energy is going to replace that coal fired plant or that wind farm has really put a huge dent in lowering the number of coal fired power generating plants so in retrospect it's just as micoscopic as the EV industry trying to remove CO emissions. After all it has to start at some level and point in time and over time it will become less and less microscopic and more mainsteam, but hey enjoy your high and mighty attitude because I personally don't care for it and it is that type of mentality and attitude that is holding the country and world back from developing better transporation solutions that are friendly to the enviroment with your narrow minded attitudes.

I think I like Bill Y and the engineers idea better then these two. Maybe it's not about green or costs but leading the innovations.

This has been shown around Portland, Or for the last few years.
