Re-powering!

While my comment is only from reading about other sailors' success .....
We do have a young couple posting regularly on the Ericson owners site that repowered their (restored) 35-2, and went cruising. They built out their own system, and do seem to be pretty technical and handy. Starting from Seattle, they sailed down to SoCal, and then to the South Pacific. Now they are in NZ ....
(quarantining near some other sailers that we know -- it's good to be in paradise during a pandemic.)

They deliberately chose a boat that sails very well in light air, and indeed they do sail a lot. (!)
They always maintain some reserve power for getting into harbors.
They are making this system work in the 'real world'.

While my own sailing and cruising plans do require a diesel aux, at least this is one actual data point for an example of long distance cruising with only electric power.

Worth noting that they are now completing a new hard bimini with added solar cells on top, also. :)
Certainly, kudos to your friends for their accomplishment! They are clearly sailors! But I have to point out (my nature) that they might have accomplished the same w/o “auxiliary”, diesel or electric. Also, a small yacht making thousands miles passages probably could not, or would not, carry enough diesel fuel for the yacht to make much motor distance in windless conditions far from services. So, the crew would likely be just as conservative, or nearly so, with diesel auxiliary power use. And not to diminish in any way, but only to note, a largely down-wind route much of which is at tropical (warm) latitudes. No diesel-fired heat needed. So, I can’t see how the adventure adds much about the effiacacy of electric auxiliary, given that the auxiliary itself would be of limited need.

Sailing is a thousands year old activity; whereas, auxiliary power, other than human, for sailing craft is less than 250 years old, even for the military. Sailors basically do not need it much at all!! So an accomplishment with one versus another type of largely unneeded thing says little in support of the preferred, or “justified” use of either of them in this example. :)

I'm not back to shore power at night but can use a generator to top up the batteries for the next time the motor is needed.
So you use a gas powered generator to charge batteries? Your neighbors must like that. Physics says you will pollute more by charging batteries with fossil fuel than if you burned the fuel in you A4. But...it will be quite when you motor 150 yards after $10K investment. Do I have that about right?

I would bet that by far, sailboat cruisers average fewer than 100 hr/year on their engines (Most never, or rarely, go far.) On my Bavaria 38E with its 39 hp Yanmar, that’s a bit less than 100 gal of fuel/yr. Non-commuters to work, both cars together, we buy maybe 450 gal/yr, if even. Commuters probably buy at least twice that amount. So, for those concerned about carbon footprints, buying or leasing an electric car first could be far more to the point of conservation than converting to an electric auxiliary for a SAILBOAT.:doh: Put the $10k there!

the OP needed to replace his aux. choose to go electric. is cheaper for him. asked if any others had done such. sounds pretty logical to me. prolly wanted to learn about installation.

A small price to pay to be rid of the gas, oil, fumes, noise, vibration, etc. (Anyone need a 1968 A4?).
If your A4 has fumes, noise, and vibration, there is something seriously wrong with it. My friend has one in his Catalina 30 and the engine is so quiet you can hardly tell it's running. And no vibration and fumes, either. But then, he maintains it meticulously.

I agree, I think gasoline engines are far more pleasant to operate. My tournament ski boat was a dream to run ... as long as the water was smooth. Those flat-bottomed boats are pretty miserable in chop!

Quite right. I have a Yanmar 1GM on my Ericson 26. It's a little one-lung diesel. And while I don't find it all that loud, my friend's A4 just hums by comparison. When he has it idling in the slip about all you can hear is the "sploosh sploosh" from the cooling water coming out the exhaust. It's much quieter than the portable generators than have been mentioned in this thread as a means of charging batteries.

On my Ranger 29 the A-4 was so quiet (Compared to an outboard) I asked a friend who knows the engine to come on board to see if the engine was running up to speed because I didn't think the tachometer was correct. Actually I don't remember if it had a tach but I was concerned it wasn't reaching full power. It didn't smell bad, and had very little vibration.
There is a lot of talk about aromas stirring memories and even emotions. When I smell marsh and diesel I can be immediately transported back to Freeport LI on the Dad's Sumnercraft transiting the marsh on the way to the inlet. It's never a bad vibe. And the COPD is getting better!;)
