How Much Is An Electric Boat

What Is The Bollard Pull Test

How I build my electric outboard motor

Bollard pull is a measurement of the pulling power of a watercraft. It is defined as the force exerted by a vessel under full power on a shore mounted thick post . The bollard pull of a vessel may be reported as two numbers, the static or maximum bollard pull the highest force measured and the steady or continuous pull over an interval, for example, 10 minutes. Bollard pull is primarily used for measuring the strength of tugboats.

How Do I Calculate Expected Runtimes

Frauscher Launching New, Much More Powerful, All

Since runtimes are based on your battery supply , amp draw, cruising speed, boat type and weight, and water conditions. Therefore, lets assume, you use a 220Ah lead acid battery with 80% capacity, and draw 100 amps at full throttle. Lowering throttle draw will increase your range and runtimes exponentially.Example: Run at a low throttle

Step 1: Ampere hour : 220 AhStep 2: 220 Ah x .80 = 176AhStep 3: 100 amps / 4 = 25 amps Step 4: 176 Ah / 25 amps = 7.04 hours of run time

How Can I Save Money

When buying a boat lift, you may find it cheaper to go for a third party boat dealer rather than the manufacturer. Also, consider looking slightly used models to save up to 60 percent.

Shop around. Contact different dealers and get the average pricing. Do not just go for the cheapest, but for the one that has a reputation in giving out quality boat lifts.

If you are up to it, you can make your own boat lift. All you need to have is the right knowledge and the appropriate materials. eHow.com gives a suggestion on how to make your own boat lift. You can check it out in order to save money.

Now 1hp Draws About 750 Watts So 9hp X 750w = 675kw Electric Motor

At 48V, our motor should give us 6.3kW, which is slightly less than what we would need to push our boat to hull speed in calm conditions. But that is something we never intend to do. It takes a lot of power to push a displacement boat to hull speed. So the slower you go, the greater your range will be. However, it takes a long time to cover that distance. So, there is a sweet spot right around 4 kts where you make good headway, while being conservative with your power consumption. Of course, these are merely suggestions. Real world conditions are rarely perfect and adding 30% redundancy is often recommended by many motor companies.

We only use our motor for close quarter maneuvering where sailing isnt an option, like a marina, or tight anchorage, so hull speed and redundant power werent something we worried about when designing our system. We often sail on and off the hook and choose places to anchor with few boats around.

The Relationship Between Voltage And Thrust

As we mentioned, Trolling motors come in 12v, 24v and 36v variants. The higher the voltage, the greater the thrust. A 12v motor requires one dedicated battery, a 24v requires 2 dedicated batteries and a 36v requires…you guessed it, 3 dedicated batteries.

In general terms voltage/thrust ratios are as follows:

12v motors = 55lbs. of thrust or less

24v motors = Over 55lbs. up to 80lbs. of thrust

36v motors = Over 80lbs. up to approximately 115lbs. of thrust

If you want the ability to fish for multiple days without recharging, you’ll also want to consider stepping up to a motor with higher thrust/voltage.

Moving from a 40lbs 12-volt motor to a 80lbs 24-volt motor will provide you with significantly more run time. You may not need the high-end power available with the 80lbs motor, but the additional power and extra voltage will provide dramatically more run time. For more details on understanding and calculating run time, please see our guide on Calculating Motor Run Time.

There is a lot to talk about here. Hopefully you can follow along and not fall asleep. LikeI .am.right.nowwwwwwww SLAP!!! Ok! Im awake. Where was I. Right, wiring.

With no degrees or formal training in electrical engineering , we had a lot of learning to do. Here we were, with a big heavy electric motor we knew nothing about, a boat it could theoretically push and the dream it would all work in the end. Now all we had to do was figure out how to get the motor to spin the prop. Sounded simple enoughright?

Pounds Of Thrust To Horsepower Chart

I have a 55 lb. thrust trolling motor, would that be equal to any horsepower?

Whats the equivalent of a 30 thrust trolling motor in HP?

To help you quickly find the result, here is a chart that compares pound of thrust to hp.

The estimated thrust to horsepower is based on the method #1 of lbs to hp calculator with 85% motor/system efficiency and 0.9 power factor.

And here we mainly discuss the pounds to thrust on the boating field with a relatively limited thrust range commonly seen as below and not the jet engine field.

Pounds of Thrust
AQUOS Haswing

So 1 hp trolling motor basically equals to 70 lbs of thrust, and about 0.6 horsepower is a 55 lb thrust trolling.

Craigcat gas

Here it is. The schematic youve all been requesting. You may notice that it is drawn for a direct drive system, where the motor is used to electronically shift from forward to reverse. We have since installed our motor in front of our old transmission and no longer need the Fwd/Rev circuit. However, since the majority of set ups out there use the motor to achieve Fwd/Rev, we wanted to show our diagram depicting a similar set up. If you end up with a Series or PM motor, you should be able to modify this diagram by excluding the 12V bank to motor connections. However, many of the components, like the contactors, require a 12V supply to operate their solenoids. So you will still need a 12V accessory bank. This is often the house bank of a boat, since many smaller boats run 12V house banks anyway.

We Have Yet To Use Our Motor For More Than 30 Minutes At A Time

As of today, November 2016, we have sailed over 3000 miles up the east coast of the United States and through the Bahamas to Haiti. We have yet to use our motor for more than 30 minutes at a time. The majority of use comes when we drop the mainsail and back down on our anchor to set it. Most of our sailing has been offshore. But, we have also sailed on the ICW and recently sailed 25 miles up the Cape Fear River to Wilmington, NC. We have sailed under many bridges, some on set schedules, others open on demand. In all cases, we sailed under. We have found that having a solid plan and the patience to wait for the right weather and tide is the key.After all, we own a sailboat. They are inherently slow. We are not in a rush. We love the idea of being self-sufficient. But, for those who sail with schedules, are short on time, lack the patience to sit out a wind hole, feel the need to power their boat to hull speed, enjoy maintaining a diesel engine, or are just set in their ways, then an electric motor probably isnt the right choice.

The More Watts You Can Store The Longer You Can Push Your Boat

As mentioned before, our motor is a SEPEX motor. This meant that the field and armature needed 2 separate voltages in order for the motor to spin. The way we solved this problem was with two separate battery banks. The field is powered by the house bank at 12V. This bank consists of two deep cycle batteries wired in parallel giving us about 250Ah at 12V. So far, it has held up great. It powers everything onboard including the inverter and laptops. We use about 30Ah on a slow day at anchor, and around 70Ah when sailing or when were both using our laptops all day at anchor. The nice part, is that even on a cloudy day, our 480W solar bank can replenish that before dinnertime. But well talk more about that in the next section, CHARGING below.

There are many types of lead acid batteries on the market. Dont get too invested in brand. Most of the batteries on the market today are made by the same two companies. Trojan seems to be the brand of choice for many. We found batteries for sale locally and for $100 each, including delivery, we couldnt pass them up. We also knew that the flooded lead acid bank we installed is only temporary. Like weve said before, this whole Electro-Beke thing is really one big experiment. We have plans to install a LiFePO4 bank soon enough. But well tell you all about that in the WHATS NEXT section below.

What Are The Benefits Associated With Hybrid And Electric Boats

There are numerous benefits to electric motor propulsion including that its quieter, more efficient at lower speeds and less smelly. Its also expected to lower overall costs of ownership by reducing or eliminating the needs for oil and transmission fluid changes, filter and impeller replacements and starter problems. Theres less to winterize too. Additionally, unlike diesel or gas engines, electric motors provide full torque instantly so boats get up on plane faster. Aftermarket conversions can use existing drive shafts and components so there is a cost-savings when re-powering.

As discussed before, the prices are high because the demand of electric skateboards is too low. That is why it is unreasonable to reach an economy of scale by upscaling the production processes. The only way the prices will go down is when its demand increases substantially, and new manufacturers enter the market. This healthy competition will play its part in getting the prices down.

Hybrid And Electric Boats And The Current Marine Market

As mentioned, now that hybrid and pure electric propulsion systems have proliferated within the automotive industry, hybrid or electric boats are beginning to gain steam. Still, the marine world is a relatively small niche market that tends to follow rather than lead other industries in terms of innovation. Currently only less than 2 percent of boats today are integrating electric or hybrid propulsion. This slow adaption is partly due to the unique issues of boating. Boats have a different frequency and variance of use than cars and the market has many segments where boats are used differently, making it hard to build one solution to fit all applications. However, a few companies are trying to change all that.

Power and auxiliary sailboats are typically propelled by inboard or outboard engines using diesel or gasoline fuel. A growing appeal has been placed on electric motors for these purposes i.e. pure electric engines powered by large battery banks.

As with any new technology, theres an adoption curve. The early adopters are the technologists, visionaries and tinkerers and they make up only about 15% of the market. In marine, these are distance sailors that need efficient sustainability and autonomy but theyre also ferries and water taxis that operate on bodies of water where combustion engines arent allowed. Then come the trailerable towboats, tenders and fishing boats as well as charter boats to fill the boating sweet spot of the 25-75 foot midrange power market.

How Often Do You Drive The Electric Motor

Depending on how often you drive, it affects which type of battery we recommend. When used frequently, lithium-ion batteries are the most suitable type of battery. This is mainly due to longevity. Lithium batteries are significantly lighter and therefore the best choice for gliding boats.For smaller to medium-sized battery systems and with a normal driving frequency, we usually recommend AGM batteries. AGM batteries are significantly cheaper. They are also lighter in weight. However, a detailed comparison of the battery types can be found in Chapter 3 of the guide.

A Mixture Of Displacer And Glider

There are also the hulls of the semi-planes. Semi-planes are able to hit their bow waves and partially overtake them. This way they can reach higher speeds of 2 to 2.5 times the trunk speed.However, you cannot completely switch to gliding. The idea behind the concept of the semi-glider hulls is that higher speeds can be achieved with the same amount of energy.
