S/V Déjà Vu is a 1972 Catalac 9M catamaran, for sale by owner. A hybrid with sail/solar propulsion, its main advantages are: sustainability, silence, no fumes/engine troubles, little energy costs, easy maintaining. Thanks to the big battery we can use 230V equipement – no more gas installations!

After more than 30 years of experience in designing and building solar powered boats, I ventured into the combination of sail and solar propulsion for a sea/inland waterways cruising boat using only renewable energies.

It is an ideal 9m boat to live and explore permanently on it, you hardly find a better seagoing boat of this size which is thanks to the shallow draught also fine on inland waterways: its width of only 4.4m let you pass most locks in Europe: it is so much richer for cruising using not only the different seas but also rivers and canals.

So I replaced 2020 the diesel engines by 2 electric motors. These have the advantage that they require hardly any maintenance and are also highly efficient in the partial load range.

The weight of the electric motors including its Lifepo4 battery is the same as the 2 diesel engines. I used the existing propeller shafts, which are driven by the electric motor via toothed belts.

With a Catalac 9m, an average speed of over 4 knots can rarely be achieved under sail in the Mediterranean. I keep this speed constant with the motors as soon as the wind dies down. The battery allows 24 hours of autonomy or 150km in calm conditions. The PV modules produce an average of 20kWh/day. There is also a 2kW charger if there is electric grid power available.

The Déjà Vu is a low-cost prototype of this propulsion concept: Up to about 3 Bft, solar propulsion is superior to sails: this saves sail area as we do not need big sails in light winds! – I replaced the original rigging by an easy tiltable 8m-mast running only 2 foresails. This leaves more space for PV.

The roof  over the cockpit/steerhouse is tiltable left/right to increase energy production and easying access to the cockpit.

Since 2020, we sailed this boat from Portsmouth/GB-Seine-Saône-Rôhne-Sicily-Greece-Cyprus-Aegean Sea-Peloponnes-Sicily-Sardinia-Marseille-Rôhne-Saône-Doubs-Basel-Rhine-Main-Danube-Black Sea to Mangalia/Romania.

In May/June 2024 we continue back to the Western Mediterranean where we intend to sell the boat due to our age…

You can meet us in Mangalia, Varna, Istanbul, Thessaloniki, Corinth or Dubrovnik to have a look at this uncommon boat. It is even possible to accompany us on a cruise!
