*** Eric's electric propulsion idea deserves it's own thread, so I have split it off of the Olson25/ SF to Hawaii. s/v Faith
coming up from mexico is even worse.I have never done it but it requires a very powerful engine with range.its only the first 600 miles north from hawaii or so until you get out of the intertropical convergance zone.then a moter of even slight power is really all you need as the wind and current is virtually nil.even aboat like ours only needs a 3 or 4 hp motor to move it some what.one of the things Ilearned from drifting 10 days altogether on that first return was patience.even the slightest wind to move at the slowest possible pace is a wellcome relief from utter silence and stillness of doldrums.the a-4 was removed before I aquired this boat(I had them remove it) and I am going to experiment with a portable diesel generator and the electric motor from a table saw.during a recent power outage here in florida due to the storms,some one here had a 4kw portable generator(diesel powerd)and it ran 2 10 inch table saws simultaineously.after seeing the power these saws have I got to wondering....what about removing the powerhead from a dead outboard .....putting this moter from the saw.....now wait a minute....that generator ran TWO tablesaws.........now I am thinking TWIN SCREWS>>>>>
"I am going to experiment with a portable diesel generator and the electric motor from a table saw"
Ok, sorry I'm slow at times. Your going to use a portable diesel generator to make electric to run a electric outboard, to move the boat... :-\
And your not using a regular inboard diesel engine to to do this because... ???
installation of a complete diesel powerunit is not cost effective for this boat.a diesel engine ,transmission,cutlass bearing stuffingbox,propshaft,propellor controls,fuel tanks,guages,alternators,variuos other unknown requirements,not to mention atleast a month in dry dock....this expense is too prohibitive for a boat that only cost me less than 3 grand. this boat was derelected and dismasted when I got it.a portable genset is available here for less than 1000 bux,its removable,dead outboards abound here,and the table saw motors are cheap.this entire idea is "modular"and is something I could put together in no time.rite now there is nothing where the old a-4 was
ah so, Ok now I get it!
I thought it maybe the cost. I forgot about all the stuff that goes with the motor and you are bare to start with.
Eric,
Single phase, 110v table saw motor is usually .5 hp, 1.5 max (rare). You might be better off to consider some of the high thrust trolling motors.
I drug a Coronodo 27 AND a 14' skiff out of the weeds with one (36# thrust) one day, one a friends dingy. I was quite impressed.
Quote.........now I am thinking TWIN SCREWS>>>>>
You would be able to back that thing like it had wheels on the bottom!
you may think I am alittle out of it but I am being completely inspired bywhat these cuban rafters are coming over here on.....I mean they are using weedwackers as outboards.not only that but this diesel electric thing is what ww2 subs used so its nothing new just a scaled down version
Not at all Eric,
I think your idea has merit. I know there are some big name Yacht peddlers looking into this design also.
The diesel/electric idea is a good one, and with a solar array and a decent battery bank I think you could have the additional advantage of silent anchoring, or close qtr's maneuvering.
I think it might be cheaper to buy a trolling motor then a table saw and an old outboard (unless you had both on hand). But then you will have to rig the motor to the lower unit on the outboard, and deal with a motor that was not designed for the marine environment......
I do not think the horse power issue is a huge one. You might not make hull speed with a trolling motor, but then again I think most boats tend to be over powered.......
There is a 21' Lugar (not the classic open Lugar, but the small fiberglass model) that sported a 15HP Evenrude! He could push a bow wave like you would not believe......
He was finally convinced that motor was too big for his boat, I suggested a 3 to 4 hp. He bought an 8hp 4 stroke Johnson.
I have a 6 hp on my boat, but have used my 2hp dink motor to push it (prop barely reaches the water). Some folks row boats like mine for short distances, I guess it is just a matter of what you are looking to do.
Here is a good link to an 'electric boat' site. (http://www.electricboats.co.uk/intro.html)
They desccribe the requirements to move a boat is much more modest terms then most Sailors are used to;
QuoteWhat you now know is how much power your hull needs to achieve cruising speed.
Essential though this is, it is far from the complete story, and several other factors need to be taken into account if you are to get an accurate estimate of the design motor power.
Before doing that, it is worth pointing out the very low powers needed (0.5 to 1 hp) to achieve the cruising speeds typical of an electrically-powered craft. I.C. engine zealots tend to be disbelieving that such low powers could be of any use at all in driving a boat. What they forget is that the power required increases approximately as the cube of the hull speed, so that very small speed increases need major power increases, as the boat speed approaches its hull speed. Other significant loss factors for an I.C. engine are in the propellors used (small diameter at high revs.) and in the gear box and drive train. When these factors are combined, it isn't suprising that motors of 20 hp or more are often fitted to quite small boats (see Lynch .pdf above).
Here is another good link on sizing an electric motor to drive a boat,
"HULL DRAG and POWER REQUIRED - MADE SIMPLE" (http://www.solarnavigator.net/hull_drag.htm)
I already have a bran-spankinnu 8hp yamaha out board that I have on a costom made transom mount.I made the mount myself out of galvaized steel pipe fittings.this mount can hold 2 motors just like it.necessity it the mother of invention.when I made land fall on the triton the a-4 peeeterd out on me,and I quickly improvised an outboard mount by placing a plank of wood across a rung of a side mounted boarding ladder.so instead of drifting powerless on to a lee shore I had an auxiliary 4 hp outboard side mounted.I improved on this idea with my current boat and indeed already motored about 300 miles along the icw with it.
Check out these steam engine outboards! Paul

anything is better than having to get out and push
Eric,
Came upon a Minn-Kota with a couple corroded connections in the control head (should not be too hard to fix). Big power head on the thing..... Maybe a 65?
I will let you know what I find out (as to how well it moves Faith) once I get a 'round tuit) and get it fixed......
When I had the marina here I was going to build a little tug boat to tow in broken boats and put around on - about 18ft in length with a nice enclosed pilot house. I had a few options for power - an inboard engine and tranny - an outboard in a well OR I could install a foot from an outboard and power it with a small engine for a riding mower via a belt drive and the impeller could feed a water box for the exhaust. This last idea came to me one day while moving all the junk around in the shop and it could be converted to your use by swapping an electric motor for the small engine. IF you were to cut a hole in the boat and mount the foot in that it would be like a saildrive - the elec motor could be placed a few feet away if needed. It would take having the boat out of the water and some glass work but it would be there
Hey I had one of those weed wacker outboards. It was sold by Sears some years ago. 1/2 hour of listening to that thing and I would want to shoot myself. I have a friend with an electric powere Coronado. He posts on www.latsandatts.com under the name carrickbend.
I've been interested in electric propulsion for a long time. Here is an interesting plan from Glen-L Marine.
http://www.glen-l.com/designs/special/electricdrive.html
I have leads on portable diesel generators.for the up and comong storm season I am hoping to get one soon.the place is called CORMAC and it is in hialeah florida ph# 305 477 6922.a 6kw generator is 1200 bux.they have smaller ones .the 4kw is only 900 bux.I will put one where the inboard should be and exhaust it thru the existing motor exhaust.the problem I may have is fitting it thru the companionway. I will put the biggest one in possible.
Just passing through, so I will leave you with this one to ponder for your next project. ;D
http://www.ev-america.com/
http://www.ev-america.com/page4.html
looks good.I really think I am onto something.this electric propulsion I feel will do very well in a no wind/current situation---as is in the high pressure doldrum no -wind-for-days situation.even the slightest power is all that is needed---any thing is better than having to get out and push.I am still curious as to the power and torque or just the plain old abilities of those dc powered bass boat type trolling motors.if anyone out there in sailfar land has any experience with longterm use of these motors on the typical 30 foot or so sailboat please raise your hands.....not all at once please
I have a dream of a cruiser catamaran with twin electric sail-drives and mooring in a tidal area to ensure good charging twice a day. Props in the water and wants to turn - let it. I assume the prop size will be larger than normal and will be a drag when sailing/charging - so what - I'm cruising...
my dream boat will be electric powered 8)
I had a trolling motor on a Venture 21 - 28lbs of thrust Boat weighed less than 2000lbs. It would take EVERY BIT of power in a group 27 battery to push the boat 7 miles at around 2knts. I think you need to think about what you will need for power and at least double it. I tried to use a 50lb thrust motor on my Cal 25 and almost ended up on the bank when the wind shifted a bit while I was coming off the mooring and I did not have enuff thrust to power the boat into the wind. You also need to think about the weight of your battery bank - If the genset is going to be where the old engine was where are the batteries going?
You will still need to have a waterbox installed in your exhaust to be legal so that has to be pumped in. For a really clean looking install I think you will need to pull the boat and do some fiberglass work but when its all done I think you would be happier with the results both in performance and appearance. From the description of pipe fittings to build the bracket I can only immagine that in the future if you decide to sell this boat that this would not be a good selling point no matter how well the system works. I know I have ripped stuff off of a boat that the previous owner thought was great just because it looked like poop to me. I'm sure as the galvanize wears away, the rust streaks on the hull will be a pain to remove too.

Inboard prop gen. First you need to see if your transmission can handle it. Some of them must have the engin running to move fluid inside or else you will burn out the trans. If you have to put the trans in reverse of brake it, you will not be able to use it as a gen.
Solar or wind may be an option to this.
You can get a 1000 W gas gen that may do you better than using the motor.
About $ 800 for Yamaha.

I've swapped my 8 hp Yanmar for an electric motor. I've mounted my re-e-power system 3000 motor to the hull of my boat. She's ready to go in the water this week. The attached picture shows the motor before the final painting with ablative paint. It runs on 4 series 27s @ 48 volts. Cruise range at 5 knots is expected to be 5 to 6 hours. I'll be testing it this weekend and will report back.
Oliver,
What kind of boat do you have. It might help us know how efficient your system is to know the length, weight, etc. I was also wondering if you have it set up to charge your battery when it is not running.
Fair winds,
Pappy Jack
Pappy Jack,
She's a 28' Cape Dory Intrepid. Displacement is 7500 pounds. The engine will recharge under sail given about 4 knots of speed. I'm just getting her in the water now so I can only site the specs. I'll let you know my observations when I've got some first hand experience using it.
Oliver
Great, I hope it all works out. I expect to need to replace my moror in 2 to 4 years. It would be GREAT to get an electric instead.
Olivertwist,
Grog to you for bringing the RE-E-Power system to the table for consideration. Here is their website (http://www.re-e-power.com/index.html) in case anyone else is interesting it looking.
Looks like about 2x the cost of a new outboard, but much less then an inboard re-power (of course you have to add batteries). Btu then you may be able to remove the fuel you would pay for... unless you run a little honda to charge the thing every once and a while when the winds have been light.......
The picture you posted does not look like a Cape Dory, maybe that is the picture from their web site? if so, do you have any pictures of your install?
I really look forward to hearing more about this system. Thanks for the post!
Faith,
Thanks for the grog. That is a picture of my boat, Credo. The Cape Dory Intrepid is a Chuck Paine design. It's one of the few fin keel designs CD produced. I believe they only made 10.
Oliver
I am really interested in the recharging aspect. Did they tell you how many watts you would get at 4 knots. Or maybe you could figure out a watts per knot chart ( I know you'd rather not) but I will if I get the figures! :)
Just feeling rather sparky...
Newt.
newt,
I'll see if I can make the knots per Watt chart. I didn't get launched last week as I'd hoped due to a flaw in my glass job. I hope I've got it fixed now. I'll double check on Friday and try to launch again on Saturday. If there are no leaks I can give her a test drive.
Oliver
Fantastic! This stuff is the things dreams are made of. If you could get a decent charge we may never need the generator again! Just think of a boat where you ran the detestablel once a month and in emergencies only. It takes the breath away. ;D
Newt,
I ran across some data yesterday and I thought of you and this thread.
Data (*):
A three-blade propeller with shaft locked can increase a vessel's resistance through the water by 20%.
Have that same propeller free to spin but NOT able to rotate at the proper speed (the example given is using the shaft to turn a generator) may increase vessel's resistance by an ADDITIONAL 25%.
It is further stated that the maximum drag appears with prop turning around 100 rpm.
Just wanted to share; this may impact the design of the system you envision.
(*) Source: Hiscock, Eric, Cruising Under Sail, p 193.
Not know much about props but they are designed to push the boat and are not as good at the same RPM's going backwards. Would it help if the prop was desigend to be used as a generator?
Captain,
I am not sure I understand your stats. What I think you said was that a boat slows down 20% with a fixed propeller and an additional 5% (25% of the 20%) with the propeller turning. I would agree with that, as the surface area of the prop functionally grows larger. This is all with a fixed prop. I plan on having a variable prop in my system. This will solve two problems- going into reverse, and be able to vary the resistance to the generator to optimize electric generation to the needs of the boat. I also forsee a possible drogue effect when running downwind, although a true drogue has many important actions on the boat which could not be duplicated with a propeller.
I think the main advantage would be simplicity (believe it or not). No wind generator, no solar panels, no electronic cutoffs for the above, and all power needs of the boat located in the engine well- including the batteries. Just a system that I think will and can happen. Even with present technology... :)

The point was that it's not just that the prop is turning, it's that it's not turning at the correct rotational speed for the linear speed through the water. The internal friction of the generator causes a slower rotational speed for a given water-prop torque generation. In other words, you are not only fighting prop-drag, but are also transferring generator drag to boat-drag.
I have absolutely no clue how a feathering or folding prop alters this - changing the prop pitch does not effect the internal friction of the generator. Maybe you can minimize the loss, though?
Rather than saying the boat speed will be reduced by 25%, it is probably a bit more accurate to say the boat is 25% harder to push. This may or may not equal a 25% speed reduction depending upon wind speed since the power curve for the sails is non-linear.
Just came across it and knew you were thinking about a prop shaft driven generator. As a potential light air performance issue, I wanted to share it just in case.
Not trying to suggest your approach is not a good one....
This discussion is a good one. As I understand resistance to a hull through water, it increases in a log rhythmic fashion till planning speed is reached. So lets say a hull is going 75% of its hull speed, increasing the pull on it 25% shouldn't drop the speed 25%. Since most sailboats already have a prop in the water, The decrease (5%) might be almost unmeasurable.
How would it compare to the pull behind generators? So many questions- I guess we will just have to get a few answers.

Agreed for that part of the power curve.
On the topic of drag, it's the other end of the spectrum - very light air, slow boat - where a small change in drag makes a relatively large change in boat speed.
If you are in the doldrums (or otherwise light air), a few percent change in drag can mean the difference between moving SOME and not moving at all. Even 1 kt is still 24 nm per day. ;)
Since we are in the engineless thread, I'm assuming we don't want to motor through the light stuff. ;)
Quote

I've no experience with them directly, yet, but definitely plan to have one. Some folks shun them and I've read the increased drag cited as a reason why.
Now Captain, if you have a variable pitch prop, you could turn it to no drag (or very little) in light airs, thus you would have the advantage over a typical sailboat in light air, the only problem I can see is cost. Reduce the cost and we may have a winning system.

Yes, but if it's feathered, it's not turning the generator, right? Am I missing something?

Oliver
I can't wait to hear your results and impressions. I am really hoping you are happy with the system. How long have you sailed your boat? If you have a fair amount of experience in different conditions you should be able to give a pretty good evaluation of the real costs of the drag.
Even 20% might not be as bad as it sounds. I bet most boats are losing %20 to poor sailing trim or a less then steady hand on the tiller.
True, a lot of the inboard engin boats have to lock the prop to save the transmission. If not aligned with the keel would create more drag. Yuk.
Quote from: Lynx on June 11, 2008, 11:58:37 PM
True, a lot of the inboard engin boats have to lock the prop to save the transmission. If not aligned with the keel would create more drag. Yuk.
Right, but what Hiscock was saying was that this is additional drag over and above what is already there from the prop with the shaft locked. Maybe we could call it something like "asynchronous rotational drag" or something fancy sounding. ;D
I kinda see it in my mind's eye as a kind of 'reverse cavitation.' In cavitation, the prop is turning too fast; in this case, it is turning too slow.
No doubt light air is tricky anyway. I recall that the Pardey's wrote quite a bit about "Keeping Her Moving in Light Air" as an important component of sailing far on the cheap. Drag played heavy into their discussion and key there was feathering props.
Heavy air gets all the press, but I think light air makes the sailor. At least light air gives ME the opportunity to show how much I have yet to learn.... ;D
Back to a feathering prop in light air-
I see a couple of situations.
No prop rotation in light air- no generation- your are just trying to get the boat from one place to another. If you have full batteries- you may electric motor for a while. Otherwise you fold the prop to the least resistance.
Air starts to fill in: If you really need juice, you waste it on the generator, otherwise you sail.
Above 7-10 knots of wind- do both with the caveat that you have more drag, so you may wish to keep a little more sail out. Once you have your 800 amp hours charged up, you should be able to enjoy a movie and a motor into a harbor for free :D
(all of this is theory and has not, as yet been tested in anything larger than a bicycle)
feeling sparky!
There was a problem with my initial installation. She took a little water when first launched. I've already reglassed the hull/motor interface and will be down at the boat tomorrow attempting to over build it before attempting to relaunch and test.
All indications are that the re-e-power motor is working fine but my installation was lacking. With luck, and the grace of God, I'll get back to you on Monday with better news.
Oliver
The 'grace of gosh', is the result of someones filter. To me it doesn't sound quite right.
Quote from: olivertwist on June 12, 2008, 10:44:23 PM
To me it doesn't sound quite right.
To each his own "gosh".
I've been using the re-e-power system 3000 regularly now and I'm gaining confidence in it. It runs reliably and is much quieter than the diesel. However, it's noisier that the diesel when you turn it off and sail without power. It hums while you sail. It's not a big deal but it surprised me.
I run the engine for about 25 minutes on the way down the river to LI Sound and about the same coming in. I've been running it at about 10 Amps which gives me 3 to 3.5 knots. Wide open it draws 90 Amps. I haven't run it long wide open so I don't know how fast it would push me. At 10 Amps I should get 14 hours with the 4 Series 31 batteries.
I keep Credo at a slip with electric so I charge up at the dock. The charger delivers 9 Amps and the time spent charging is about equal to the time spent discharging.
I don't have much to report on recharging while sailing yet. The winds have been light most of the time so I haven't tried this much. yet. I did note that engaging the re-gen costs about half a know just as advertised. I was also concerned about the induced drag of the pod but the boat still gets to hull speed in moderate winds so it doesn't seem to be an issue.
So far I like the ease of operation, the quietness, the lack of fuel and smoke, and the ease of maintenance.
Thanks for the update, here is a grog to celibrate!
Bet you are glad it is workingout well, thanks for being the guinea pig for the rest of us. I look forward to hearing more about it as you get more experience with it. ;D
Any more news Oliver? That hum may be the generator noise, which if working, would make me feel good.
Captain, as I look through this thread I realize I may not have answered your question- how would I generate electricity in light air? Either 1. no generation because I have a big enough battery bank or 2. Solar.
Newt, nothing new yet.
The wind forecast looks good this weekend so I should get to try charging under sail. I plan to reverse the wires on the ammeter to see what kind of charging current I get.
Is this a 48 volt motor?
10 amps X 48 volts = 480 watts (less than 1 hoursepower). If you put up 1000 watts of solar panels you could handle it without anything else.
How big is 1000 watts of sloar panels?
An option.
A 130 watt solar panel is about 26" x 60" or so... you'd need eight of them to get 1000W. That would require a space 5' x 22' or 10' x 11' or so. Not really feasible on a boat that is less than 40' LOA, and tough to do on a boat that size even.
The updated wind forecast for CT doesn't look good for testing the ability to recharge under sail. I'll be bringing my 1.8 kW gas generator with me. I may motor across LI Sound and back (or until the batteries die) and then use the generator to drive the 48V recharger to get back. The charger draws 9A. 48V * 9A = 432W. The charger has more than enough power.
If I may tease you a bit-
The above logic on solar panels implies that you are running your electric motor directly from the solar array, and yes it would have to be big- impractical on a sailboat. If however you already had a large bank of energy saved (say 1000+ amp hours at 12 v (12000 watts), you could motor through the doldrums or other windless area, or not use your water generator for light wind sailing, then repelish with a smaller solar panel and a water generator as the wind picks up. This large battery bank would be with the rest of the lead- close to the keel. In fact, if I got serious with this, I would look at taking a part of the keel out and replacing with secured lead batteries.
Since we don't spend the majority of time cruising (most of it is spent at anchor or in ports) the sun would keep our banks up and enough electricity in reserve.
BTW- 1000 amp hours could be as little as 10 batteries- or about 600 lbs- and that would be for a larger boat. I would think that boats under 30 feet could probably cruise for a lot less. Remember you would be replacing your engine and transmission with this arrangement, so you would get heavier, but perhaps by not very much.
Just saw this on the Pearson Ariel board, where it was posted by the user 'Commander Willbe' He is looking for a Pearson Commander (same hull as the Ariel, longer cockpit and a shorter cabin) Anyone know of any for sale?.
It looks like another promising option.

Just wanted to share an email I got from the Electric Yacht folks. I know a few of us have been looking into re-powering with a green solution. Anyway, the email mentions that if you order in August, they are taking 10% off (due to summer doldrums). It wasn't on their website last time I checked, but this comes from Scott McMillan directly.
Thanks Nowell,
I went ahead and merged this into the thread on that topic. I am sure that anyone looking into this will be interested in the discount. :)
Greetings
Just a little FYI for anyone interested.
The Zen 24, a sailboat designed in Japan with an Asmo Marine Thoosa 6000 inboard electric propulsion system will be on display and available for demonstration sails in Marina del Rey, CA on September 8-9 and September 17-19. In between these two dates, the boat will participate in the ASA Flotilla to Catalina Island, Long Beach, Dana Point and Newport Beach. After the demonstration, the Zen 24 prototype will be offered for sale and orders will be accepted for new purchase. Yoh Aoki, Guiness Book record holder and solo circumnavigator and designer of the Zen 24 will be available to meet with interested people .
There will be a demo in Northern CA as well in Redwood city. I will be helping with this.

This boat is based on the design Yoh Aoki used to circumnavigate for a 4 year solo sail. This fits the Sailfar Philosophy so I'd thought I'd post.

...and speaking of "zen boats" We are moving on-board the " Zen II " in Sept, to prep for the Pacific passage next year.
Zen, If I get back from the San Jauns by the time you do the Redwood City show, I will come down.
And... wow pretty exciting making the move on board and eventually Westward!!!
