... and not just for fishing! ;)

Check out this one. What nice lines

“This elegant boat slides across Lake Starnberg in almost complete silence; for the Laguna 760 is electrically powered. While its looks suggest a speedboat along Riva lines, the engine is far from conventional, boasting a high-performance electric motor with an output of 40kW.

The power is drawn from cutting-edge lithium polymer batteries, propelling it to a maximum speed of around 40 km/h. At normal cruising speeds, the batteries last for six or eight hours. Even when drawing a heavy current, the batteries should be good for a two-hour trip.”

I have no connection to this company in anyway what so ever. I just thought it was really beautiful and the electric motor was a neat twist with the cost of gas being what it is.

Here is the link if you are interested in more photos, it is only in German.

Please add any new ones that you find to this thread.

Very nice boat. I really like the lines and the looks.

Re: Electric boats are coming of age ...

if the technology is there I think it would be great for a medium to small fishing boat. 75% of your time is spent in one area and not cruising around all day.

While great for leisurely cruising, You would still need a gas powered boat for water sports and such.

Re: Electric boats are coming of age ...

i would definate entertain the idea, even a hybird. but there is still more technology to be worked out. how do i keep from getting electrocuted, getting back in the boat?

That is something that has always concerned me, and it seems we are not the only ones.

I know that one manufacture in Germany of high power outboard motors and new generation batteries, will not sell them to you for refitting, if you don't don't allow them to do the electric installation.

We are not talking about 12volts being used anymore.

Re: Electric boats are coming of age ...

I like the concept of electric boats, the problem I have is that we are still burning something to make the electricity for the battery.

With the larger and more powerful trolling motors coming out, systems in the 36~48V range I am surprised we are not reading more about electrocutions on small boats.

Re: Electric boats are coming of age ...

The boat at the top of the page is using Lithium Polymer batteries, needs 120 Ah. at 220 V to produce the 55hp claimed, and achieves a top speed of 23mph.

They claim a minimum of two hours (max power) and a maximum of four hour (cruising at one quarter power) of battery life between charges.

Time needed for a full charge is not given.

Re: Electric boats are coming of age ...

the math never works for me :D


But at 745 watts per HP thats allmost 41000 watts or 186 amps at 220 volts

Re: Electric boats are coming of age ...

How about this this classically styled barrelback from Edison Marine, located in Portland

“The Edison Cruiser features true EV performance. Featuring twin high performance 9 inch DC motors, twin 500 amp controllers and twin propellers (thats right, twin props on a 17 foot inboard boat), Edison moves fast and powerfully out of the water.

Edison uses proven EV building blocks, meaning electric vehicle components that are commonly used for electric vehicle implementations. The current implementation uses twin Warp9 9 inch DC motors running at 144v nominal. The motors are connected directly to the shafts without reduction. The battery pack features AGM batteries which offers a good balance between energy capacity, availability and cost effectiveness. Edison uses 500A or 1000A controllers with JRMerritt throttles. The high performance battery charger is can accommodate either 110v or 220v AC input. The 15Kwhr battery pack can be fully charged in 4-5 hrs.

The Edison Cruiser can run at 5-6mph for 8 hrs on the standard 15Kwhr battery pack making quiet all day cruising a reality, and a joy.”

Yah, and that Edison boat starts at $100,000. Hmph! Of course, it's made of mahogany. I imagine they could do a fiberglass version for a lot less, but these are rich folks' boats.

"Well, of course, we only use electric boats at the summer house, don't you know. They are much more green than the old Chris Craft."

Re: Electric boats are coming of age ...

it would be great when you are under steam and making no noise at all and at some places in Holland you are allowed only with an electric boat and this is one good looking craft

Germany and Switzerland are also shutting down one lake after the other to combustion engines.

Who boats on these lakes now, you guessed it the super rich.

I also know people in the States though who refuse to take out medical insurance, but have hundred thousand dollar campers for their hunting trips.

I guess it is all about where your priorities are.

Re: Electric boats are coming of age ...

It doesn't have to be an expensive boat to be electric, you could just use a golf cart motor mounted to a lower unit.

Or one of Briggs & Stratton new motors as in this guys project ...

But like all things with new technology, if you want fast, you have to pay for that privilege.

Re: Electric boats are coming of age ...

Being shocked in an electric boat is no more of a risk than any other power. The motors and batteries are not being submerged. We climb aboard craft with the trolling motors down all of the time and don't think about it.

Electric craft have been around for more than 150 years. They were popular in the era of 1890 to 1910 and have seen a renewal here since 1980. Most are displacement craft of classic lines, yet I have seen some good designs in V bottoms ans planing craft. Most of the systems I am familiar with use golf cart technology.

They are heavier than IC rigs, but can be competitive dollar wise as long as you don't expect to stay above planing speeds too long.

If money were no object then I would take TD's idea of hybrid power, my love of steam, good accommodations, high sustained speeds, environmentally friendly fuel and roll them all together to have a vessel that would impress the neighbors. My Uncle Sam has one, but I am still trying to figure out how he trailers the Sea Wolf!:D

Re: Electric boats are coming of age ...

I'm thinking the high dollar electric boats are marketed to people who can't run gas powered boats on their exclusive resort lake, resort lakes where you can't run a gas powered boat. If you buy a $2,000,000 house, what's another $100K for a cool looking Eboat for the lake?
