AW: [Electric Boats] Re: New guy Questions

 

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

Glenn,

I'm interested in your budget. How much would a diesel re-power cost for your boat? Are you considering electric primarily because you think that it is a cheaper alternative to ICE?

You should seriously think about the compromises that you're signing up for. A 500 lb flooded or AGM battery bank will drive your boat about as far as 0.75 gallons of diesel. The Vega is a small boat, do you have room for eight 6V golf cart batteries or four 4D batteries?

A new Beta twin diesel weighs about 200 pounds. A decent sized electric drive will weigh 200+ lbs more than a diesel system, including a full 8 gallon fuel tank, that is sized for your boat.

How long have you been sailing your boat? How much fuel do you usually burn over the course of your regular trip? When I realized that I rarely burned one whole gallon per trip in my boat, electric drive became more feasible. I'll spend at least 80% of what I would have spent for a diesel re-power that I did myself, so I'm not doing it to save money.

As long as you approach this project with your eyes open to what it really means, then you shouldn't be disappointed. i've seen a number of newly converted boats that obviously did not meet their owner's expectations.

Fair winds,
Eric
Marina del Rey, CA

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 (http://www.thunderstruck-ev.com/index.php?dispatch=products.view&product_id=55) $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?
