LiFePO4 is a better battery, no doubt about that. Expense is the only real issue left to solve.

But the other half of the equation is charging. There is not a good solution to that coming that I can see.

I think its quote the added value if you take into account its a certain market niche

the boats being offered where very well maintained, in marinas...and fitted for daysailing...

which is what most electric conversions have been applied to....

and last but not least its still a sailboat...
Well they ask more but that is very different than selling for more. There is a Bristol near me that has been on the market for at least 4 years. Was listed by a broker for a couple of years and is now on sailboatlistings. Looks like a nice professional install. But I can't imagine using it on the Hudson river as we have shifting currents and folks here motor a lot, especially upstate. Sail one way and motor the other way.

Broker thought it would be a perfect match for my preference for a composting head. Guess she thought I was an environmental hippy. Guess she is nor far off as I do enjoy sailing on the Woody Guthrie and she is electric powered. But she mostly day sails with shore power charging.

Do you have any links about Lagoon giving up on electric drive. I couldn't find any doing a quick google search.

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Not really. They didn't really make a press anouncement, they just stopped offering them. My bet is they are waiting for the technology to advance to the point they feel it solves the problems they encountered, then will reintroduce it.

Why? What were or are your reasons?

You give up range. You will have greater expense when replacing batteries every few years than the cost of maintenance of a diesel in good condition. Fuel costs cannot be the reason as fuel use by a sailboat is very small - probably a lot lower than the cost of driving to the boat in a vehicle over a season.
Because some of us actually sail. We actually read charts, and watch the ebb tides. We Sail! It sounds like from reading this thread most motor sail here. This may not be a good site for me after all.

Re: Repowering with an electric engine?

My plan is this

1. install electric drive with proper gear ratio to prop it will regen at 3 to 6 knots(don't know how much yet)
2. install 8 batteries for a 48 volt system
3. Add 2 or 3 solar panels 24 volts each to charge batteries with a solar controller.
4. add a Missouri wind and solar wind generator but mounted upright with a vertical axis blade with a wind controller.
