Apparently, our ancestors relied more on their ability to hear the lions rumble from further away than seeing it from near!🙈 Whish you all the best luck&fun. Than you very much for your kind labor🖖

exploring life soft starters are capacitors that go before the electronic that holds the amount of charge to start that device.

Battery recharge the cap for the next use . They do this in automotive as well for the start of the gas vehicle because it easier to pull from a cap vs battery on high draw

Great as long as you are sailing. But if you stay at one place for a few days, you will run out of energy.

Good update and explanation. It really is a matter of doing a thorough analysis of both supply and demand (i.e., generation and loads). At the end of the day, it is a math problem and understanding what those loads are (both peak/starting and continuous run) is a big part of it, whether talking about a small sailboat of a big warship. You maximize supply and minimize demand to the extent you can. With older boats (and they don't have to be that old) things like replacing lighting with LED lighting can pay HUGE dividends in power loads. Some really odd things can be big electric loads...heating elements (hot water heater for example) can have huge continuous loads while running while big motors (winch for example) can have big peak/start load (current draw). The klystron/magnetron on a radar can be another big load. Older electronics also tend to draw more power than newer, solid state stuff (depends on how old your stuff is). An easystart can also reduce start loads for things like the A/Cs and sometimes make them options on batteries... In planning an electrical configuration upgrade (as you are effectively doing/have done) it helps to map out each item on the boat and what it draws (simple multimeter and lots of switch flipping can help measure things out) and give you an accurate power budget planning input. I am really curious about the going 100% solar option and dumping the generator idea. As you say it gets rid of weight, noise and fuel use but really removes surge capacity unless you use the engines and cross-connect your system. It would seem the air conditioners are the big units that right now you don't have the ability to run for extended periods without supplemental generating power you would lose if you get rid of the genset. Are you thinking you just don't use the a/c that much (and are not likely to in the future) or that you really can cover them with solar? Certainly that is a lot of weight (but capability) that makes the Leopards so comfortable that it would be a shame to lose them. Do you think it's possible to get enough solar generation to also accommodate using the A/C (at least on one side of the boat) most of the time? Maybe with the addition of one or two more Lithium-Ion batteries vice getting rid of one of yours? Curious about your thoughts and appreciate the video!

In case of need, you also have lots of vertical real estate on the sides to add some panels, and possibly flexible panels to add to the sails. But that’s some budget.

That’s how I set our boat up. Although a much smaller scale I don’t want to mess with my cranking batteries while at anchor. I want to keep them separate, fresh, and hot for when I start the motor. You said not many people do that but I like that better than relying on “house” batteries when you’re ready to move. I’m not sure exactly how lithium works but I assume if they are highly discharged you still have the 12 volts needed to fire off the motors.

The most brilliant idea I heard for a generator is what Silent Yachts did: connect a standard marine engine only to an electric motor used only as a generator. They used the same type of AC electric motor and controller as their propulsion electric motors. (To be clear, the engine is not connected to a prop in any way, just the electric motor used as a generator.) Even if you don't use electric propulsion, this is a great solution for a generator: standard marine engine parts, support and maintenance, plus highly efficient and relatively low cost electric generator. This should be much cheaper, better supported, more efficient than using a genset. Electric motors for this purpose are widely available in the DIY electric vehicle market. They're a great value, efficient, modern, compact, reliable, etc. Agree with everything the Kelly's recommended in this video. It's great advice.
