Convert your sailboat to a clean, quiet electric drive! Eliminate noxious diesel fumes and the frustration of filling up at the pump. Enjoy your sailboat to the fullest, with a silent drive and truly fresh air. Installing an electric drive can often be cheaper than getting that old Atomic4 rebuilt. more
Our DIY sailboat kits are easy enough for the handy type to install on their own, but if you prefer we also have installers available the world over. Interested in becoming an installer? Great! Let's talk! here
Here's a video made by a customer using our boat kit as well as a lithium battery pack with our BMS and Programmable Charger. here

Motor Types There are advantages and disadvantages to each kind of electric motor. Some manufacturers use abbreviations to describe their motors, others use the full words. We have used whatever the manufacturer prefers, but when abbreviations are used, this is what they mean: more

‘When you take on a project that’s electric, it makes you think hard about efficiency so the air conditioning, water heaters and everything in the galley has also been carefully selected to use less power.
The market has responded to demand, and battery and motor technology has come on leaps and bounds, driven in part by the rapid development of electric cars.
For all the many green attributes that using the power of wind offers, there is no escaping that for most, fossil fuels still represent some part of sailing – whether that be a diesel engine to motor in light winds, onto and off a mooring, or to generate power for onboard electronic systems. Even a small tender used to go from ship-to-shore is often fitted with an outboard motor.
Jeremy Rogers’ yard in Lymington is the birthplace of the iconic Contessa designs and a veritable temple to long keeled, traditional craft.
A large added benefit with two propellers is the very much lower propeller losses. A conventional single prop set up has losses of more than 30%. Around 20 of the 30% is burned on giving the water a rotation. After the propeller, the water does not only flow backwards, it is also circulating – a movement of no use. By putting a propeller behind another propeller and letting them run in opposite rotational directions, the flow after the second propeller can be made to go completely straight. Then you end up with roughly 30% losses in the leading propeller and only 10% in the trailing one – moving the overall efficiency from 70 to 80% which translates into a 14% increase in range.here
And don’t forget how efficient those hydrofoil boats are. By flying above the water, they use 80% less energy than a typical boat that planes on the water’s surface. [links]
That high power comes despite the drive pod having an ultra-compact, torpedo-shaped design and weighing just 50 kg (110 lb).
Lastly, the team had to solve the heat issue. Any electric motor can put out additional power simply by increasing the current supply. But an overly powered motor will quickly burn itself out without effective cooling. The long, streamlined shaped of the pod and its submerged design meant that the motor is cooled by a large volume of water that spends a long time in contact with the sides of the motor. That allows the motors in the C-Pod to operate at higher power levels than outboard electric motors that don’t have the advantage of constant water cooling. [links]
To create the new design, Candela’s engineers had to first solve several design challenges. here
