You sure use the term "are here" very loosely. Are they possible? Yes. Do they exist? Yes. But when you start asking questions such as "are there a significant number sold and installed?" or "do they have any noticeable market penetration?" then the answer remains a resounding "no."

Well yes. As I noted on another thread, a 35' boat has enough space for solar panels to produce 2-3 hp as long as the sun shines. That isn't going to push you very fast.

So IMO solar panel powered boats will always be a gimmick, not a real world solution unless solar panel efficiency gets five times better (almost 100%) than it is now.

I've followed Solar Sailor since their first ferry built around 2001. Five Solar Sailor's were built ultimately. Now, the company, Ocius, seems to be focused on unmanned craft for exploring the seas and for security purposes, but the idea of the Solar Sailor seems largely by the wayside.

I thought the concept of sail and solar was very interesting and the unique sails being used got my attention. But it seems a lot of vision in this and other projects and then things keep dying away. It's now been 5 years since Planet Solar completed their circumnavigation.

Since many boats spend 75% of their time in a marina, I would think that a hybrid drive system would be able to keep the weekend boater satisfied. It won't supply all his locomotion needs, but the diesel will be run considerably less.

Because it's so far from being practically useful.

Billionaire toys, Science Projects sure fun to learn about.

Put a diesel in the mix at least you eventually get where you're going, but efficient it's not.

Unless you have no schedule. . .

So far, I don't see how it helps. Greenline is the largest seller of Hybrids so focusing on a Greenline 39, on a fully charged battery pack it can run 20 miles at 4 knots. At 6.5 knots it can go about half that. So, what is it really doing for you?

There is a new Greenline 33 that just showed up in our marina. Very interesting boat. It's totally silent when it leaves and returns. I haven't been able to talk to the owners very much about it. The website shows it comes with a Volvo D3 and an electric motor.

That's their norm.

Agree. Way too early for electric to go mainstream in boats in my opinion. That said, my wife just got an electric car (VW eGolf) and after owning it for a few months, I would seriously consider an electric car for myself. So quiet and smooth, and obviously a ton of torque. Didn't expect that I'd like it as much as I do.

Sorry, didn't mean to throw the thread on a separate tangent.

Time to consider building diesel electric trawlers?

Well, there's another thread on Wider 150, which takes a very unique approach to diesel electric.

BrandB, maybe I should have said small trawlers, less than 50ft. OAL.

Generally speaking, cruise ships are diesel electric.

I know what you mean, but also these things start larger. You see it accepted in 150' boats and it may well make it to 50'.

I suspect Popular Mechanics has addressed this possibility in the last 50 years.
In my case, PM has made me dream about things that might be but, I sure wont live to see it.
