Why the Aequus 7.0 ?

Bruno HERVOUET: "I created Aequus 7.o for my family!"

Sailing champion of France in 2005 (one-design yacht racing), Bruno HERVOUET successfully launched in 2000 the Open series 5.70 and 5.00 when he managed the boat building company Phileas.
On his personal 1930 CG PETTERSSON boat (a swedish day boat) he tested the electric solutions.
In collaboration with the naval architects FINOT-CONQ, he created the ideal day-boat to sail with family and friends, to have lunch at anchor, at a mooring or just to take a swim.

The Aequus7.o fulfils all these needs in the best conditions of comfort.
 

What is the motor's power?

Electricity changes the understanding of motor power.

The power rating of a motor does not matter in terms of navigation, what is important is the propeller thrust. This is what propels the boat.

Motor power is measured from the propeller shaft and is transformed into thrust by the propeller.

Because of their strong torque at low speed, electric motors (and particularly synchronous motors) can drive a high output propeller (large surface and low speed rotation) with a low power rating.

The Aequus 7.o does not exceed the legal motor power limit (4.0 Kw nominal) and thus can be sailed (in France) without a permit at a speed of 7 knots (13 km/h). A more powerful combustion engine would be needed for an equivalent output with the inconveniences of noise, exhaust fumes, smell and require a permit.

Autonomous ? Solar energy? Both?

Electro-solar !

Aequus7.o is equipped with a set of AGM (absorbed glass mat) batteries which do not require servicing and can take up to 400 heavy discharge cycles (up to 80%) and much more if lighter.

The 6 m2 solar panel roof protects you from the sun and provides the necessary energy to run the electric motor or recharge the batteries.

For occasional use and with sunny conditions, the solar charge totally compensates the energy consumption. The Aequus 7.o is then totally solar powered.

For more intensive use, or less sunny conditions, the batteries act as a buffer and become the main energy supplier. These can be then rapidly recharged from a 220volts plug. The Aequus is then operating in an electro-solar mode.

The crew can monitor the battery charge level at any time and can thus modify the speed in accordance with the distance to sail, the degree of sunshine, the trip’s programme and available recharging facilities.

Generations of navigators have been concerned about wind conditions before getting under way, so there is nothing very odd about looking at the sun and acquiring new practices!

Performance ?

The speed is the same as on a sailing-boat of the same size!

The naval architects FINOT-CONQ (four out of five winning yachts in the latest Vendée Globe race!) have designed this energy efficient boat in a digital testing tank.

This solar boat reaches a speed of 7 knots (13 km/h), and matches that of a yacht of the same length under sail or when using its motor.  

How is the Aequus 7.0 built ?

The Aequus 7.o has a composite fibreglass hull that is built to order and can match any customer colour choice.

 

 

 

A wide range of upholstery colours is available.

Standard trim includes a leather-sheathed wheel, ash veneered interior and solid teak bulwark.

A purpose built trailer can be supplied as an option providing independence to launch the boat or winter it. The total towed weight being less than 1600 kg, most saloon cars can comfortably tow the Aequus withought special licence.

And the security ?

The Aequus 7.o has been designed to conform with CE standards category C.

Which means that in France, the Aequus can be sailed safely at sea within a range of 6 nautical miles from shelter.

In other countries it depends on the law.

The storage of energy and its transfer to the motor are in low voltage (48 volts nominal).

What is the maintenance and after sales service ?

Strictly minimum.

Apart from hull and deck cleaning, Aequus 7.o does not require any maintenance; neither oil change nor servicing. The electric motor is a synchronous motor and is therefore maintenance free.

The batteries are sealed and require no servicing or topping up. In the winter, if the boat is exposed to light, the solar charger will maintain the battery charge level and performance. If the boat is in storage, the quay charger can be plugged into a simple 220volt plug and will charge automatically.

All spare parts, electric, mechanical or electronic are available from stock from our after sales service.
