Would you guys with electric propulsion consider such a trip?
Oh, and at Bahama’s fuel prices, it may cost as much as $1 to make the trip.

If it takes 19 hours to fully charge the battery from fully discharged, then it’s going to take three full days from Solar.
I suspicion that a fully charged battery equals about $1 of gasoline or less.
Cost wise you’ll never break even, much less save money

My 20 HP four stroke outboard weighs 30kg. That is a big motor, and an electric outboard is more comparable to a very small gas outboard, how do you save 30 Kg going electric?

20 hp 4 stroke is way more than 30kg, i think 46 kg. Then add 20 L of petrol in tank and you have total weight of nearly 70 kg. Compare this to 14 kg Can do 14 nm trip but need to watch usage. Either way, gasoline or electric one needs reliable way to paddle as things fail on such trip. 19 hours full charge is on 12v socket. We are keen kayakers and long trips are always made with kayaks even when we had planning 10 hp mercury that managed 18 kn.

I suck at math, but isn’t that about 85 amp hours?

Yup, confirmed. This much pumped solar in yesterday at a constant rate of 50 W. I left charging overnite as no chance of depleting my 400 AH bank. Engine on davits, one plugs in after done in the evening and in the morning 50 AH replaced. How easy is that ?

Did I mention my wife can raise now dinghy on davits ?

And taking outboard off/on will not risk my back or other injury any more.

Actually, no, as I have had the same small gasoline outboard for my tender for something over 15 years. They last a long time and are quite reliable. If/when I need to replace it, I think a propane outboard may be a good choice as I have carried propane aboard all 4 of my cruising boats none of which required gasoline except for the outboard.

[QUOTE=Scout 30;2789877]Our Bauer 10 is an absolute joy to row & sail.

Beautiful little sail boat. Little pricey. But I can see the value. However when fully rigged she is over 150 lbs. that is verboten on my trimaran. I think captain of Bounty could have sailed this all the way back to England and not bothered with Indonesia. He he.

If you want to be sustainable AND flexible AND have a safety redundancy, get an electric for your usual dinghy engine, with a tiny petrol outboard in the transom as a spare, or for when you need to go further than the electric will allow. Yeah you gotta carry some gas, but you get the best of both worlds.

At 30 years old, our new bad boy is the very definition of sustainable. It can sustain a plane with four well-fed adults and all their stuff onboard, as well as sustain a respectable momentum if towing the mothership becomes a necessity; it might even be able to sustain towing a waterskier... but I don’t anticipate the need for that.

I’m all for sustainability.

Note: I can buy three of these for the price of one Torqeedo.

guys, you all seem to be geniuses with maintaining petrol engine. I am unfortunately not. And outboard maintenance cost me more than maintenance of both diesels in 4.5 years. When I looked at maintenance schedule for petrol engine, even 0.5 HP

And when I looked at electric

The annual maintenance cost to tune up our 2 stroke outboards has averaged out to be $100-$150 per year, having Italian mechanics do the work. We can have lots of tune ups at these prices before it even approaches the cost of an under-powered Torqeedo.

Come to think of it.... We can even have one of our 15hp Mercury outboards stolen then replaced.... and still be over $1000 ahead of the cost of a .5hp Torqeedo.

regrettably my experience is totally different. Probably because AU mechanic working hour pay is in stratosphere if you can get one.

I would maybe think different if i had access to cheap quality enthusiastic mechanics.

We can agree on this. I’m sure my experience would be completely different if my Mercury repairs took place along the US coastline. Fortunately, I found a very good, family owned, honest Mercury dealer 10 minutes from my house in America, and I have the Italian fellow near Venice along with a mechanic friend who spends a month each year on the boat. Italian labor costs approximately €35 per hour for an experienced journeyman not affiliated with a shipyard.

Another point, all of our motors are 2 stroke if that makes a difference.

Haha yes well, you know me slightly on here, so you know I don't practice what I preach: Brand new Yamaha 20hp with a 15hp Merc in the transom for the spare. Planes our 3.3m all aluminum RIB 4 up all day long

so you one of these that buy big boat so they can carry BIG dinghy.

Happy fuel burning. It is good people come with different wiring.

If it still has the oil injection pump, I’d disconnect it and run pre-mix.
You will use a little more oil or course, but it’s not going to be much

[a64pilot]

If I didn’t want gas for whatever reason, I think I’d go with a dink that rowed well over electric at this point.
Now just from watching others, but it seems that the ones that row well, don’t give up anything to a Torquedo, they do just as well in higher wind and seas.

Thanks, that is what I plan to do.
