[Electric Boats] Re: New guy Questions

hob tonn
G'day People.
I hope that this will not turn up in everyones spam box.
I believe that if people wish to change to electric power then they should do just that, without
people trying to talk them out of it or showing the negative side of things.
I have found in the past that what didnt work for other worked perfect for me and visa versa.
Some speak of regen, yes If your a weekend sailor and only go out for two hours a day or thats the max
distance that you sail, yes Regen is out. But if you just motor out of a slip you can leave and not use 2% of your? battery bank aswell , depending on how big your marina is.
?
I have electric on my 42' ketch, I wouldnt trade it for a zillion desiel or gas engines. Im not a weekend sailor.
I will cross again the pacific in the boat. As we all should remember sail boats have no engines. Only a secondary being said that the Wind and Sails are your Primary. Are we sailboats or are we power boats?
?
Do we wish to sail or do we wish to run the engine at 5knts? and play the part. I kno in case of emergencies
engines are a delight. But what did people do 55 years ago? Not even a VHF to cry into or a SSB.? And
Cell Phones were only a reality in a Dick Tracy Show.
?
People if you wish to have electric get electric. What didnt work for me doesnt mean it will not work for you.
Maybe you will be the one who revolutionizes batteries or a new style of electric motor. I love my electric boat.
And when people are in the doldrums? afraid to run thier desiel or gas engines due to the fact they wish to save the petro to motor in to the islands. I can move along at a few knts per hour with no wind all day long. even if its 1 knot per hour under power and direction, thats 24 knots further than most will be and some times even more depending on what direction they are drifting. Also moving at 1knot per hour a person could run many hours befor even using up 50% of a 48vt bank.
?
So all the Killjoy's out there, Let the people be who they are and maybe one of them will invent something that you will purchase in a few years for your boating fun.

Cheers

I have a strong mechanical background and some electrical experience mostly automotive and a little residential, that being said I can safety repair most anything; it's designing where I may need some help. I have a very healthy respect for electricity and always ensure cables are properly terminated, sealed and secured, all grounds are in place and all batteries secured. > First off budget is an issue I don't want to go over $4K, from prop to batteries, is this possible? Rough guess shaft, prop, bearings, etc $1K. Kit something like Thunderstruck, Sevcon Brushless Sailboat Kit - 8.5KW () $1.5K. Wiring, motor mount, belt drive reduction, misc bits $0.5K. That leaves $1K for batteries and chargers, not much I know, but I could add more later. I would thinks 48 volt would be better (at least safer), but amps are starting to get high. Batteries, I guess I would have to go with AGM, have some space, would love LiFePO4 but out of my buget right now. Any one have any suggestions? > > Boat Specs > 1971 Albin Vega > LOA 27' > LWL 23' > Beam 8' at WL 7' > Displ average 6500 Lbs > > Glenn > |

What are you using for an electric motor system? any details boat displacement, battery size, motor size?

You make a good point. I'll have to remind the guy badmouthing electric conversions on the Cheoy Lee board that spent 6 months and more than $6000 converting his sailboat that doesn't perform the way that the electric drive vendor led him to believe. He's now trying to sell his boat for what he paid before the conversion, and he's not getting any takers. There have been a number of people that have come here asking about converting ski boats and 50'+ houseboats to pure electric. I believe that it is our responsibility to give them enough real information (not marketing hype) so that they can make their own choices. But perhaps I shouldn't be so negative, at least we'll have more slightly used components available at lower costs for our own projects after their projects fail....

I read your comments as realistic, not negative. I always appreciate your contributions here because they are objective and well-grounded. I also like how you run the numbers to ground. That said, I think the cost comparison is difficult. From what I can tell, you can put a diesel in for what the electric conversion will cost, but the diesel would have to be used. A new diesel would cost about double what the electric conversion would cost. Maybe the used diesel will outlast the new electric installation, I don't know; but it does seem like apples and oranges, don't you think? Paul --- In electricboats@..., "Eric" <ewdysar@...> wrote:
