The Electra is an electric ferry with hydrofoils

The Electra was designed by a company in the United States. It is an electric ferry that also has four hydrofoils and offers many advantages. The transport of people and goods by sea is almost the basis of logistics today.

The Electra has features that offer advantages

Much more cargo can be transported and its cost is much lower than air transport. Ships, ferries and other vessels call at ports carrying all kinds of cargo, people, machinery or goods.

However, the resulting pollution is very important, both for the seas and for the atmosphere. One of the seas where most ships move is the Mediterranean Sea. A sea that has dreamlike tourist attractions and that must be taken care of.

The electric ferry was created by a company from the United States

The US company Boundary Layer Technologies based in California designed a Ferry that fits that care. The ferry is fully electric and can carry 150 people on board.

It is designed with hydrofoil technology, which the California company specializes in. The ferry was named Electra. It is specially designed to transport tourists or travelers between islands. That is why it will make its debut in the Mediterranean.

Advantages of a hydrofoil ferry

Hydrofoil technology is based on the ferry “flying” over the water. This reduces the drag by half. Not only that, but the motors are electric and harness twice the power, increasing speed and range. In addition, this gives it greater range.

The Electra ferry reduces operating costs by 35%, according to its manufacturers. The comparison is based on ferries with fossil fuel engines. The hydrofoil raises the hull of the ferry a few centimetres above the water reducing friction.

The new ferry has four hydrofoils and two engines located in the stern hydrofoils. When the vessel reaches a certain speed, it rises by gliding on the four hydrofoils.

Its range is 100 nautical miles, about 185 kilometres (185 km), and its cruising speed is about 40 knots (74 Kph). The electric motors also reduce vibration and noise on board by about 20 dB. The batteries that power it provide 9000 kWh.

It solves the range problem of other electric vehicles.

Autonomy is very important in both land and sea or river vehicles. It is one of the most relevant problems for the electrification of transport. The 185 km range is more than enough to cover 90% of the sea routes in the United States.

In the case of the Mediterranean, it would cover 48% of the route between the Greek Islands. The manufacturer stated that the batteries have a 2,400 kW charging system. This system allows recharging in just three hours. This allows recharging while passengers board and alight and leaves a longer recharge for the nights.

As for the vessel’s performance at sea, the hydrofoil design allows it to negotiate swells of up to 1.30 meters. This means that the ferry, being elevated, does not cause the swaying that is the culprit of seasickness in many passengers. Even if the draft and propellers are increased, higher wave peaks can be negotiated.

The company plans to have the first units in availability by 2024. For the time being those units will be for the United States, Scandinavia and the Mediterranean. Many are eager to see it in action
