and to think, this started out on the benefits of changing the fuel source to the stove. LOL

It wont get to the middle of the Pacific ocean, the article itself states that.....



360nm is a long way from the middle of the Pacific ocean and anyway, what sort of fool would run out of fuel in the middle of the Pacific?

Guessing it may be you thinking that you wont need diesel, the sun shines every day and you never need to use that electric stove or watermaker
You missed the point...its a scenario...one in which the electric boat will still go 100 miles a day...yours wont.

Publix has facilities to plug in electric car. Maybe soon, electric boats can motor out and plug into wind farm?

Yes, and way above I had already given a summary, which is that nobody can prove which is stove is safer. And I could be lying that ive read reports of more new boats installing them.

I think ive read that some of the hybrid boats that service them do already do that.

An automobile-like hybrid (which drives the wheels directly from the ICE much of the time bypassing the hybrid feature) would require expensive additional equipment that would seldom be of much use.

The sailboat community has been experimenting with this for some time, having the advantage of an alternative source of propulsion, but other than some daysailers it has not taken off. There have been a few high profile attempts by production builders, all have failed and many of those boats converted back to diesel auxiliary. Even if the needed 10x improvement in battery technology appears, the charging problem remains.

I'd suggest beginning work on an anti-matter fuel cell. At about 25 teraWh/kg, a few grams would last the life of the boat.
Those more and more companies building them claim reductions like 25...30% fuel savings.

Sure, they could all be lying, so more and more feel like building them and lying to....like thiscnew Norwegian one......."2190 HYBRID FISHING BOAT
The market’s “smartest” yarn boat. With the electric hybrid propulsion solution, you reduce greenhouse gas emissions by 25% and runtime on diesel engines by as much as 75%. This significantly improves the working environment on board. The boat has energy-efficient heating through heat recovery from the diesel generators ."

In some use cases, there's definitely potential for that. But in many others, there's very little advantage.

For the previously mentioned wind farm service boats, it makes sense. For someone cruising inland canals / rivers with fairly short distances per day and often having shore power overnight, it makes sense. For someone who just takes short day trips (particularly if they don't want/need a fast boat) and might stay out overnight occasionally, but doesn't really travel, it may make sense.

But for the person who wants a flexible boat that can go anywhere and have good range between stops, lots of storage, etc. other options just make more sense currently. That will likely change at some point as technology changes, but we haven't reached that point yet.

And don't forget, the vast majority of boat owners don't own multi-million dollar boats. Most don't even own boats worth $300k. So it'll be a while before the price drops enough on the hybrid and electric stuff to the point where more than a small portion of boat owners could even consider it.

You missed the point

I have the ability to control my fuel load so wont run out of diesel anywhere, let alone the middle of the pacific

You don't control the sun, so you will lose the ability to go anywhere on less than perfectly sunny days or days you have no diesel.

You have also lost the ability to use your watermaker or cook food any time you actually want to make miles.

Permit me please a comment.
For the 'talking price' of $10,000 or $20,000 to install the electrical system to support more batteries, I can buy more AGM batteries, to use in my boat, than I can use in a life time. Yes, yes, as the various technologies are developed and improved the price will come down, not in my life time.
Oh by the way, I am still looking for my personal hover craft as talked about in Popular Mechanics.

Oh how I wish we could do the experiment mentioned in the scenario. In fact , at least one of the Silent yachts(that some of you guys deny exist, even though you can already buy some used ones), DID cross the Atlantic already...in stormy weather, with no sun..and still made it. But again, some of you are not up to date on the topic, so wouldnt know that.

No sun, no diesel in stormy weather and on its own bottom?
Of course you will have a link to confirm this right?

Motorboat & Yacht video review of Silent 55. Interesting concept. I like the hard-top that drops down to cover the flybridge. In its current iteration, I don't see it as more than a short range cruiser, but that's how vast majority of people use their boat.

Note, it has a 100kw generator, though the 64-footer has a 150kw generator!!! (yowser!!). At the end of the video review, the MBY reviewer kindly states several open questions on performance, including whether it will actually run self-sufficiently at 7-kts with the solar when the sun is shining. Given the earlier view of the battery remaining and speed, the numbers really don't add-up so I suspect not, but it does look like a nice boat.

Best I can tell, the founders of the company did a challenge-project in 2009 with a 46-footer to cross the Atlantic. I don't think there is much info besides the unsupported statements of their marketing department. That said, it's an impressive effort - someone has to take the first step. In a few years time, hopefully this technology will be more viable. I cannot imagine the cost to replace batteries, transfer switches, and 150kw generator - would put repowering a pair of 3208's to shame.

NOT a concept , some exist, and as you keep researching youll find at least one already crossed the Atlantic, in bad weather, with no. sun. The later ones are even better, now direct drive, no gears even. Certification, CE-A...the highest the E U has.

Yikes! A similar boat ran out of battery capacity within 100 miles, even with full sunlight. Several shorts and even a small fire in the generator when the owner tried to cook a turkey in the electric oven. One owner is filing a lawsuit for damages and false claims and has specifically ordered the electric range be replaced with propane!

Sorry, I can't find the reference - you'll have to take my word for it.

Post the link or it didn't happen.

Remember, you claim no sun , not once but twice now, so obviously it used genset
Specs say they carry enough fuel to generate 300 miles approx, far from enough to cross the Atlantic
