How To Build Electric Drive For Catamaran?

The Parallel Hybrid EcoDrive is a revolutionary technology that has been used for 15 years to electrify boats in Europe. It allows for powerful and silent electric drive systems, allowing maneuvering and sailing at hull speed. High-performance batteries from the automotive industry enable prolonged motor-cruising for up to 50 nautical miles. E-Drive is installed between the engine and gearbox, accommodating both sail drive and shaft drive configurations. Oceanvolt offers hybrid or electric systems in partnership with a wide range of multihull designers and boat builders.

One of the main issues between promoters and detractors is whether to use a pure diesel-electric drive train in a sailboat. To achieve this, a belt and appropriate size pulleys should be used, and the throttle for the beta should be adjustable with a nut. E-boats excel in long slow runs, so it won’t often be necessary to push more than 3kw into it.

The route I hope to go is around 20Kwhr of lithium batteries in a 48-volt bank for about 40-50 nm silent motoring. A simple lever to lift the driving gear up to disengage the electric drive when using the 36HP Mercedes OM636 diesel engine.

To build a fully electric catamaran, start with the desired speed and load. A 15-jon boat typically has a 5 to 10 hp motor, but a 5hp motor can be used. DIY electric outboard motors can be built using used petrol engine parts and retaining the propellor and drive.

How do you drive a power catamaran?

Center the wheel and use only the throttles to control the boat. Powercats have their engines exceptionally widely spaced apart, and are far more responsive than monohulls when steered via throttles. Generally speaking, turning the steering wheel will only serve to reduce the effectiveness of working the throttles. This, of course, is assuming you have two engines. There are a few rare cats with one engine.;

At identical rpm, the engine in forward will create more thrust than the engine in reverse. So even if the throttles are set evenly when opposed, the boat will likely slide forward a bit as opposed to spinning in its own length. As a result, when attempting to speed up the maneuver it’s usually best to favor giving the reversed engine extra oomph as opposed to the one in forward (assuming you don’t want to move forward while turning the boat).;

Check the speed and direction of the wind before docking, and remember that some cats, particularly those with low draft, can be blown around more easily than many monohulls as there may be less hull below the waterline.;

Can I convert my boat to electric?

Converting your boat to electric propulsion is a significant and rewarding undertaking. Not only are you making a conscious choice for the environment, but you’re also embracing a more peaceful and low-maintenance way of boating. With the right knowledge, resources, and professional assistance, you can successfully convert your boat to electric.

How long will an electric boat motor run?

Amperage Hour Rating: Marine batteries are rated on a metric called “amperage hours”, which is an indication of how long a battery can supply a consistent amperage. The larger the rating, the more power the battery can hold, and the longer it will be able to power a motor at a given speed. For example, a 100 amperage hour battery is one that would be able to supply 25 amps of power for 4 hours (25 amps * 4 hours = 100 amp hours) before running out of energy. Alternatively, the same battery could also supply 10 amps of power for 10 hours (10 amps * 10 hours = 100 amp hours) before running dry You can think of the amperage hour rating as being similar to a gas tank in a car – the larger it is, the more energy/fuel it can store, and the longer it can power a motor.

Motor Amperage Draw: The second factor we need to compute estimated run time is motor amperage draw. A motor’s amperage draw rating refers to how much amperage (or current) a motor draws at a given speed. A motor’s exact amperage draw rating isn’t always easy to find, but should be available from the manufacturer or, if it’s a motor we stock, from a TrollingMotors.net representative.

In order to approximate how long a certain motor will run on the water, you simply take the battery’s amp hour rating and divide it by the amperage draw. For example, for a motor that pulls 20 amps at medium speed using a 100 amp hour battery, the run time would be:

How do you size an electric motor for a sailboat?

How Do You Size an Electric Motor for a Sailboat?. As a rule of thumb, you will need approximately 1 HP per 550 lb of the displacement of your boat.

Generally speaking, a 3 HP electric sailboat motor can push a sailboat up to 25 ft and a 9.9 HP motor is sufficient for a 30 ft sailboat to motor at a satisfying speed.

However, bear in mind the horsepower you need always depends on your needs and applications.

It’s better to check the data from real-world tests to decide whether the electric sailboat motor is suitable for your specific needs.

What is the disadvantage of electric boat?

Long Charging Time. Electric boats can take up to 36 hours to fully charge, although many are faster; the time depends on the battery’s capacity and charger’s power. Still, this time can be a drawback for those who prefer spontaneous outings or have limited access to fast chargers.

Limited Replacement Parts. Finding replacement parts for electric boat motors can sometimes be challenging, especially in regions with limited access to specialized electric marine mechanics. This can lead to longer downtime in case of repairs or maintenance, which may inconvenience boat owners. However, as the popularity of EBs rises, more and more businesses offer electric outboard motors and other equipment compatible with these vessels.

After looking into these pros and cons of electric boating, you can make a more informed decision on whether EBs are right for you. Electric boating presents a promising and environmentally conscious alternative to traditional gasoline-powered vessels. The many advantages of EBs make them an attractive choice for boaters. However, potential boat owners need to consider the drawbacks and challenges before making the switch. As technology advances and infrastructure expands, electric boating will likely become an even more compelling choice for water enthusiasts looking to embrace a greener way of navigating the world’s waterways. And when searching for electric boating equipment or even a brand-new vessel powered by electric sources, consider RJ Nautical for your needs. Happy boating!

Can you cross the Atlantic in a power catamaran?

Leg One – Cape Town to Luderitz, Namibia. The first step was a coast-hugging trip up the African coast. This 502-nautical-mile trip took about three days. The goal was to top-up fuel and provisions while waiting for a good weather window. Captain Kodja noted that “a powering boat pitches more than a sailing, so choosing a good window is important.”

Leg Two – Luderitz to St. Helena. Though St. Helena lies north of Itajai, Brazil, their ultimate destination, it’s a popular stopping point for yachts crossing the Atlantic. It’s not just that the northerly route is more comfortable; there are few places to the south to stop. This 1,338nm leg took eight days of motoring and used 424 gallons (1,926 liters) of fuel. This was the last stop to refuel for the rest of the trip.

Leg Three – St. Helena to Martin Vaz Island and Trinidade. The Martin Vaz and Trinidade islands are the easternmost possessions of Brazil, and the crew made a brief stop there to perform the 500-hour service on the engines. This was another long leg at 8 1/2 days, covering 1,385 miles. It was a welcome return to Brazilian waters after a long time at sea.

Can a catamaran run on one engine?

The safe way to operate a catamaran under a single engine is to move the engine control forward slowly incrementally until the engine stops responding to the movement by increasing engine speed. From that point the lever should be pulled back again until the engine speed drops back by a measurable amount.

Like most people I am usually surprised by how well motor sailing works when the fun is over and you just need to get back upwind at the end of a long day – in a boat that doesn’t really like going upwind (and even less so if there’s a sea running). This works as well in a catamaran as it does in a single-hulled boat.

• Do’s and don’ts. DO get some manoeuvring practice somewhere where you can’t do any harm to your boat or anyone else’s.
• DO find out what the proper strategy is for efficient motoring (one engine or two) before taking over the boat.
• DO concentrate on looking around you all the time when manoeuvring
• be aware of the boat’s real movement.
• DON’T forget to use the wide-spread engines to manoeuvre in close quarter situations
• leave the rudders amidships.
• DON’T be tempted to effect make or break manoeuvres using lots of power.
• DON’T be so timid with your controls that you leave too much time for the wind and/or tide to have their way.

How much power does an electric boat need?

For displacement boats, we recommend about 2 kW of power per ton of boat weight to ensure good maneuverability of your boat. If you are traveling on the coast or on waters with strong currents, we recommend 3 kW. If you only use the motor as an auxiliary motor, you can also use a smaller motor. However, we recommend at least 1 kW of power per ton of boat weight.

A displacer is a boat that permanently displaces exactly as much water as it weighs. No displacer can exceed the hull speed, i.e. overtake the wave generated by the bow while driving with the stern. The hull speed depends solely on the waterline length of the boat. The longer it is, the higher the theoretical hull speed.

Basically, every boat behaves like a displacer at rest or at slow speed. However, a planing boat is able to lift out of the water and glide on it due to its hull shape at increasing speed. For planing, a smooth, elongated hull and a wide stern are advantageous. The hull speed is far exceeded because after lifting out of the water, the water resistance also falls away. The maximum speed of a planing boat is limited not only by the drive power but also by the air resistance.

How fast can a catamaran motor?

How fast can a catamaran sail and what are the speeds for different types of catamarans?. As we said earlier, the speed of a catamaran depends on the wind conditions and the size of the boat. Most catamarans can sail at speeds between 15 and 30 knots. Some racing catamarans can reach speeds of up to 30 knots. Of course, there are always exceptions to the rule and some catamarans can sail faster or slower depending on the conditions.

However, the average cruising speed for a catamaran is around 12 knots. This means that it would take approximately five hours to travel 60 nautical miles.

Factors that affect a catamaran’s speed. There are a few factors that can affect the speed of a catamaran. The first is the wind. If the wind is blowing against the boat, it will slow it down. The second factor is the size of the boat. A larger catamaran will usually be slower than a smaller one. The third factor is the type of sails that are being used. Some sails are designed to go faster in certain conditions than others.

There are a variety of types of catamarans, such as ultralight, cruisers, and sport catamarans which all have different amenities. Catamarans as a whole are built to pierce through waves making them a fantastic boat for ocean waters. Depending on what type of catamaran you’re in, there will be a difference in the performance of each.

Can you put a motor on a catamaran?

You’ll probably lose a forward hatch, but I would mount the motor so that the shaft and head ran right on the inside of one of your side railings and had just enough clearance not to hit the head on the railing when rotating up.
