[Electric Boats] Re: Newport Vessel trolling motors spec sheet

 

Hello All:

I did the speed and battery tests on 3 different small boats with my Torqeedo 1003 and made a video of the testing process and results. It is on youtube at https://www.youtube.com/watch?v=5O1o2ms5_24.
 
We achieved a top speed of 6.9 mph in a 16 ft canoe loaded with two men. Total weight in all three boats was 340 lbs. Torqeedo claims that the 1003 is the equivalent of a 3 horsepower gas outboard.

In all three boats, including a 10-ft catamaran, we did exceed hull speed. So it is possible to go beyond hull speed with the Torqeedo 1003. But, as everyone here understands, exceeding hull speed drains the battery in a very short amount of time.

Regards from St. Petersburg, Florida,
Skipper Pea

[Electric Boats] Saietta Motors - available in U.S.

 

The Saietta Motors are now available in North America from Annapolis Hybrid Marine, the NA Distributor for Saietta Engineering. Saietta Engineering bought Agni Motors last summer and is now working directly with Cedric Lynch to produce his DC designed motors. This is exciting news since they are working with Lynch on new, larger kW designed motors! 


There are two motors currently available, the 95R and the 119R. I have uploaded three files about these motors. You can contact AHM for more info, and you can also see the motors at upcoming boat shows where AHM is exhibiting.

Re: [Electric Boats] Re: Any experience or ideas for newbie electric conversion on Newport 16 sailboat?

 

Thanks for the input. It's inspiring to hear a old outboard can be used. I have a old Mercury mariner 4hp I cannot find parts for.  I imagine a 1hp electric motor would work on the Newport 16?   I've since bought a electric pickup truck and given up on my big electric boat project. Things are shaking out. 

 Is anyone else near Jensen Beach Fl building DIY electric vehicles?

Re: [Electric Boats] Re: Newport Vessel trolling motors spec sheet

 

John,  Yes, it steers fine buy just differential thrust.  The problem with not having mechanical steering (I do) is that if one motor goes out you're up the creek with only a paddle.
thanks,
Glenn

Glenn,
Nice looking boat!!

With the twin motors, can you steer simply by "tank drive" (set the steering wheel straight, and only adjust the throttle/direction of the two motors to steer the boat)?  That was how I was told to handle a twin engine boat at low speed, especially backing into a slip.

With electric motors, I've wondered if one could do away completely with the traditional mechanical steering and just use the thrusting of the two (fixed) motors to handle everything.

Here it is.  I have not done "scientific" calcs. but I'm guessing about 30-40%  more efficient.  Motors are 82lb. Motor Guides.  Hull is Redwing 18.  4.5 mph but that's more a factor of the hull than the motors/props.  Glenn Holland

I definitely agree with the Torqeedo being tough on the budget.

I'd love to see what the performance difference would be if you put a Torqeedo prop on a $300 trolling motor.   :)    If I ever get bored and have more time on my hands and access to a machine shop...   :)   That would be the first experiment I'd try.

I'd also love to try doing an outboard conversion.  But again... time....

 Thank you everyone for your timely advice. If I buy the 85 pound motor I will publish a picture of the boat along with its speed outcome. I would love to have a torquedo but the cruise 2.0 with external battery power is $4,000.00! Hard to justify.

So, the fact is that the 86lb trolling motor is probably a 1000 watt motor, since it requires a 50 amp breaker. 50 amps x 24 volts = 1200 watts.
So the motor is about 1.3 horsepower. Is it possible to get on a plane with that small amount of power, maybe, will it happen with a person and 100+ lbs of batteries, in a big fat dinghy, with a trolling prop, doubt it.
The propellor efficiency is horrible on trolling motors, the motors are inefficient brushed motors, so some of that power is wasted as heat. If you want your rib to get on a plane, gas or torqueedo are your options. The torqueedo cruise 2.0 is 2000 watts and as they state, equivalent to a 5 hp gas outboard.
http://www.torqeedo.com/us/en-us/technology-and-environment/performance-and-efficiency.html
So the 86lb trolling motor, would equal 2.5hp, based on there comparison, but it is no where near as efficient as torqueedo. And torqueedo doesnt have all the battery weight either.
I would save your money and keep the small trolling motor. Your current 400 watt motor pushes you at 4 knots, the 1000 watt motor will probably get you to 5 knots.
If you do get it, i would be interested in your results.

Ah yes simplicity. Has anyone looked at the Newport Vessel (trolling motors) website? There is a light and dark blue chart that shows what you can expect in hull speed with each model offered? When I ask them are they doing it with pitch, diameter, or RPM they told me they really couldn't say. They go from the 36 pound thrust that will push an 8.8 foot boat at 4.04 mph to an 86 pound that advertises a hull speed of 13.67 mph for a 13.8 foot boat !  There is even a video beneath the chart showing showing an inflatable being pushed thru the water at different speeds. High speed looks pretty fast! I currently have two 135 ah batteries ahead of my 40 pound Newport Vessel motor on my powered rowboat that runs my boat at around 4 knots and am interested in upgrading to the 86 lb to TRIPLE my hull speed. Can anyone help to explain to me how approximately doubling thrust to 86 lbs will triple my hull speed? Has anyone read the chart? Am I misinterpreting it? I would be extatic if my 9 foot RIB rowboat could go 13 mph with an 86 pound Newport Vessel trolling motor ! Let me know what you think. I am about to buy an 86 pound from them but thought I would ask you all first.

What ever happened to good simple instrumentation? 

Most anything you want to know about your system can be done with sensors and minimal electronics.  There is a lot of stuff out there for things like the Pi that are excellent building blocks.  (Didn't someone on the list said you can easily read canbus with a Pi?)

Thermal sensors, rotational sensors, shunts and voltmeters can tell you most of what you need to know about your system.

Half the fun of electric boating is what you can do simple.  :-)
