A proven hull
After several months of tests and trials, the catamaran hull was chosen. For this model, the design office collaborated with architect Jason Ker, a specialist in multihulls and racing yachts.
But rather than opting for a fully archimedean hull, the shipyard has adopted a simple and reliable technical solution, by integrating a foil between the two hulls. Located in the middle of the hull tunnel, the foil reduces drag and provides additional lift to the 7.20 m hull. All these features optimize the performance of the electric motor, and therefore its range.
A 100% electric boat
The De Antonio shipyard chose the German Torqeedo for the E23's engine. On the transom is a Deep Blue 50 R, developing 50 kW, the equivalent of 80 thermal hp. To power this propulsion system, the floorboard houses a bank of 40 kWh lithium batteries.
To enhance stability and handling, large Lenco flaps are fitted to the transom, coupled with fixed aluminum fins.
The shipyard's objective is to reach speeds approaching 30 knots, which is more than sufficient for a non-sporting vessel.
Weight-cutting and minimalism
On an electric boat, even more than on a combustion model, weight is an enemy. The technologies developed by the various manufacturers are making steady progress, but a motor-battery unit is still very heavy. While the weight of the motor is roughly equivalent to that of an 80 hp internal combustion outboard, the battery pack is imposing. The De Antonio E23 weighs around 450 kg, three times as much as an equivalent internal combustion engine.
To remedy this problem, the emphasis has been placed on optimizing on-board weight, with a slimming cure at every level. Minimalism makes sense both from an aesthetic point of view and in terms of performance. The fittings are simple, but sufficient. A minimum of deck fittings is present, the doors are in fabric and some equipment is in carbon.
Thanks to this meticulous work, the De Antonio E23 boasts a displacement of 1450 kg, equivalent to that of a conventional open hull of equivalent dimensions.
A partnership for the next America's Cup
On the strength of these undeniable assets, the De Antonio E23 has been chosen, along with other models from the shipyard, as a service boat to transport guests during the next America's Cup, to be held in Barcelona. A fine showcase for the shipyard, which has high ambitions for this well-thought-out newcomer.
