I think the key problem is one of energy storage - hydrocarbons store a lot of energy per ml and batteries come nowhere near this, so until someone invents an electrical storage system that could hold a similar amount of energy as a 600 liter diesel tank full of diesel then I think it will be a non-starter even with what can be gained from the sun, wind or sail which is finite over any given period of time.

The boats that have gone all electric are pretty much day sailors.

 

I haven't found a single link or blog of a cruising boat that is either all electric or even hybrid.  I guess in theory a hybrid (diesel generator) would work (the cruise ships are this set up) but then you have to get the higher priced batteries that are next to impossible to replace in the middle of nowhere (which are far from environmentally friendly to produce anyway so there goes that pro for doing it)

 

Can't see a weight savings as being a positive.  Weight is not really in issue in an amel. (plus it might be more with the extra batteries)

 

Since you would have to keep the diesel generator i don't see any benefit or point at all.  

 

Douglas...do you already own an Amel?

We bought it in Chaguaramas, Trinidad. But any place that makes car/boat decorations have it. 
It even reflect lights, maybe not as good as a reflex tape, but good enough to identify the boat in the dark.

We are also considering upgrading and painting the rub rail. I would like to put something in the groove such that it sticks out a little further than the rubber part, thus saving the rubber part from wear and tear. We were considering a UHMW (very durable plastic) strip. Is your adhesive metal strip thick enough for this? Can you give any more info about where you got it?


Thanks.

Re: [Amel Yacht Owners] Amel Maramu Electrical Compliance - New Zealand / Australia

David Pawley
 

I am not a Amel expert. But am Marine Engineer,ship practice is quite different to land installation the star point or negative is never connected to ships hull, main reason was that if a ground fault occurred in critical equipment at a inconvenient time (Think steering gear failure when going through heads) It did not cause failure of that gear. Circulating currents in a hull is also not a good idea with regard to Hull corrosion.
Ships & large yachts have systems in place to check for earth leakage and must be corrected pronto as another fault on a return path or phase would definitely be a issue with vessel or personal safety. It largely does away with the need for RCD devise, but not legislation. To incorporate those is a little more complex. It can be done by a good Marine Electrician but think better to try others suggestions.
Hope that helps.

Hi Eric
No, the  generator neutral is not connected to earth in Elyse.

I wonder if it should be....do any Amel "experts" have a good reason why it shouldn;t be ?

I suggest that before you absolutely ruin an Amel Super Maramu that you arrange a séance with Henri Amel and ask him why he did make an electric Amel when he was alive. I would also ask him if he would mind if someone takes one of the finest cruising yachts ever produced and bastardize it.

If Henri says that he supports your electrification scheme, I happen to know where the world's most mistreated Super Maramu is located. I think it needs a new C drive, a new motor, a new generator, a new bow thruster, new interior, new rigging, standing and running, and new sails. Although the asking price is $319,000, when the owner finally realizes what he has, or the bank repossesses it, it could be the boat that you are looking for.

Any electrifying conditions other than above would be nuts!

Good luck, and I suggest a premium membership with Cruiser's Forum where you will get much better input on your ideas. There are some real experts there.

How fast does a SM2000 go through the water at 1500 RPM? At 2500 RPM?

You don't use it much; this isn't the worry.

The second sentence is getting to the importantn part: A high end Tesla
may put out hundreds of horsepower when you slam the pedal down, but it
only takes a few seconds to get up to speed.

The continual draw running down the highway is much, much less.

The marine diesel, on the other hand, is going to need to put out a good
fraction of its peak power for the whole trip.

1200 watts is about 1.6HP.

If you want to go through the exercise, let's get the answers to how fast
you go at 1500 and 2500 RPM. We can then back-of-a-napkin some numbers to
see what battery capacities are required to let you fight current entering
and exiting harbors, etc.

Depends on the cruising pattern, and also on what other devices are
pulling power. I'm guessing that most Amel owners make significant use of
the autopilot at least and possibly things like watermakers.

Re: [Amel Yacht Owners] Would you buy all electric no diesel Amel?

Bill & Judy Rouse <yahoogroups@...>
 

Douglas E Knapp, Advanced Acupuncture & Oriental Medicine Expert

I suggest that before you absolutely ruin an Amel Super Maramu that you arrange a séance with Henri Amel and ask him why he did make an electric Amel when he was alive. I would also ask him if he would mind if someone takes one of the finest cruising yachts ever produced and bastardize it.

If Henri says that he supports your electrification scheme, I happen to know where the world's most mistreated Super Maramu is located. I think it needs a new C drive, a new motor, a new generator, a new bow thruster, new interior, new rigging, standing and running, and new sails. Although the asking price is $319,000, when the owner finally realizes what he has, or the bank repossesses it, it could be the boat that you are looking for.

Any electrifying conditions other than above would be nuts!

Good luck, and I suggest a premium membership with Cruiser's Forum where you will get much better input on your ideas. There are some real experts there.

The second sentence is getting to the importantn part: A high end Tesla
may put out hundreds of horsepower when you slam the pedal down, but it
only takes a few seconds to get up to speed.

The continual draw running down the highway is much, much less.

The marine diesel, on the other hand, is going to need to put out a good
fraction of its peak power for the whole trip.

1200 watts is about 1.6HP.

If you want to go through the exercise, let's get the answers to how fast
you go at 1500 and 2500 RPM. We can then back-of-a-napkin some numbers to
see what battery capacities are required to let you fight current entering

Depends on the cruising pattern, and also on what other devices are
pulling power. I'm guessing that most Amel owners make significant use of
the autopilot at least and possibly things like watermakers.

Re: Would you buy all electric no diesel Amel?

I too have been intrigued by this topic, I am certainly no expert however I have done a good deal of research.

Simplistically an electric motor can easily replace a diesel motor, however diesel is a far more efficient store of energy than a battery.  This then begs the question of how large a battery bank one can have, and how do they get recharged in order to be effective.

In my research it seems that the best solution would be a solar array, wind generators, lithium ion batteries and a diesel generator along with the electric drive motor.  This configuration balances weight and performance, allows for similar to greater range, probably supports greater house electrical consumption.

Lithium ion batteries are much lighter or provide greater energy density so that for similar weight to current batteries one might get 2 to 3 times the power storage.  Also Lithium ion batteries are more efficient to charge and discharge, however they are still a lot more expensive than traditional batteries.

The number of solar panels and size of wind generators one might want to or are able to install will impact the total energy availability on the boat.  It seems to me the sweet spot seems to be sizing batteries to accommodate motoring for 3 to 6 hours, but still provide essentially unlimited range.  Thus would essentially come close to achieving your goal, but protect you from cloudy windless days and extended periods of motoring.  Think Prius instead of Tesla.

Re: [Amel Yacht Owners] Re-paint of rail and metal insert

Ric Gottschalk <ric@...>
 

May I suggest that you consider just adding reflective tape to the center of the rub rail. It comes in rolls and fits perfectly. Now when I dinghy back to the boat after too many rum zwizzles, I can easily find the boat (and others can avoid it).  I also add strips to the boom and mast. You can buy it at most hardware stores.

I took the liberty to change the Subject since the discussion is changing its way.

 

When we re-painted our rail, we bought self adhesive metal strips from a company that makes advertising boards for outside use. The company also made signs for boats.

We have had in place for a year now, and it still looks as new. So there is no reason to mount a stainless steel stripe and drill holes that could cause leakage.

Colin,

 

I have posted to the photos section a picture of the stainless steel insert in the Red Line rub rail.  As you should be able to see, there are screws every foot or so.  I do not know about additional fixatives such as glue, etc.  Perhaps Joel or Olivier can shed some light on that.

Thank you Mr. Bossett for your perspective! I am not an engineer although I am good at math and worked as a programmer, I am working my way through the solution. Any help anyone can give is greatly appreciated.

 

From the super maramu 2000 user's manual:

The auxiliary engine is a YANMAR 4JH3-TE (44 kW at 2500 rpm – 55 kW at 3500 rpm).

The most efficient motoring's range is situated between 1500 and 2500 rpm.

Fuel tank: 160 gallons

Range? Not to sure about this.

Bow thrusters 10 hp.

 

The Tesla car puts out 259 hp front and 503 hp rear, so it seems to me that 60 should be quite doable, even 150 should be possible. The question is how long can it sustain that power output and how long will it take to recharge. The car has a 90 kWh battery in the top model and a range of about 268 miles or 426 km and 713 lb-ft motor torque. This seems to be about 4 hours of driving time. Not enough to even get through a whole night. Of course ships can easily carry much bigger batteries.

 

I am also thinking that a system for a ship would not need the instant torque and quick bursts of speed that car needs. A slow endurance system is the best thing. This  would likely mean a big savings in power usage under way.

 

So I was assuming having a good solar panel system. The Delos, a super maramu has a 600 watt system. Seem that it would not be hard to double that so we could say 1200 watts at full sun. This does not even come close to being enough to run the 60 hp motors so it must come from the batteries and this means that changing times will be needed and this will be while under sail or at port.

 

I was considering if it is possible to dump the diesel generator or not. Ideally I would do without it.

 

I am still in the dreaming phase, the brainstorming phase. Collecting the facts and finding the limits.

 

I am wondering how many hours under engine power is normal and how much sun time there is in between motoring times?

 

Thanks again for your input.

Re: [Amel Yacht Owners] Re: Would you buy all electric no diesel Amel?

Patrick McAneny
 

Douglas, If you decide to remove the engine from your Amel and rely on  an electric motor for propulsion, then I hope you do not intend to sell her.  I think it would be virtually impossible to sell to a new owner. I too am not a fan of motoring and  sail every inch I can. However in the real world there are days of no air or light air on the nose, with opposing current, times when weather systems are moving in, when one cannot afford to sit and wait for favorable conditions while unfavorable conditions move in. I could go on forever about situations and safety that requires reliable propulsion. Electric is an appealing idea, but better for now , left for boats making it off and on a mooring , not crossing oceans. Just my opinion .
Good Luck ,

Thanks for that link.

Main benefits would be to reduce or eliminate dependency on diesel fuel. This would both increase range and reduce dependency on good ports of call and reduce the price of running. Totally silent running would be nice too without fumes. I am also a person that loves nature and I hate seeing what we are doing to it in the name of getting more oil. Also at some point the oil will run out. It is just a matter of balancing tech with practicality and price. Solar is on the edge of becoming better than oil for cars and ships. 

If  we could even double the range of the ship (without sail) then that would be a huge benefit. New bottom coats that are being developed may also double range and eliminate toxic bottom paint. I would be happy to just loose the toxic paint.

Here is a pdf about it.

Re: Re-paint of rail and metal insert

peacock@...
 

We are also considering upgrading and painting the rub rail. I would like to put something in the groove such that it sticks out a little further than the rubber part, thus saving the rubber part from wear and tear. We were considering a UHMW (very durable plastic) strip. Is your adhesive metal strip thick enough for this? Can you give any more info about where you got it?

Thanks.

Thank you both for clearing this up as these vessels do look particularly nice with the white rub rail with stainless steel inserted into the groove on rub rail. Also noted that the Amel 55 has white rub rails too so in line with Amel's new styling. We won't be changing Island Pearls' rails yet, but may be tempted to do so now in future.

Hi Derick,

no risk of water penetration as the (brown/red) GRP rub-rail is totally external. The brown rubber (or later white PVC) insert is not watertight either, this is why you can see small draining holes under the rub-rail.
Originally, with the SM technical documents, there was a cut (hand) drawing of the junction of deck and hull, where you can clearly see the set-up of this area.
Maybe someone could post a copy of this drawing?

I have posted to the photos section a picture of the stainless steel insert in the Red Line rub rail.  As you should be able to see, there are screws every foot or so.  I do not know about additional fixatives such as glue, etc.  Perhaps Joel or Olivier can shed some light on that.

Hello Gang,


Has anyone done the above?  If so, what is the procedure?


Thanks all.
