After the catamaran projects Ocean Eco 90 and 60, and the Ocean Sail 82, Alva Yachts introduces a monohull fully electric yacht. Eco Cruise 50 has an original layout and some technical peculiarities.
The path towards green mobility is irreversible, and although the yachting sector is always trailing behind (to say) automotive, there’s plenty of new projects and models entering this segment. Alva Yachts is one of the most recent players, and has already introduced some projects (under construction, not just on the paper) of fully electric catamarans and sailing vessels. The latest model to be launched though will be a monohull yacht, named Eco Cruise 50. Of course the 15.20-meter yacht will feature electric motors, having been designed by HennDesign specifically for it. But it will also sport a peculiar layout made to maximize space, and customized solutions with plenty of possibilities for the interiors.
Eco Cruise 50 HP can reach 20 knots!
As for the other projects by Alva Yachts Eco Cruise 50 is shaped around a solar and electric approach towards navigation: the technology is not an add-on but a central design feature. The most obvious characteristic that underlines this fact is the ample roof line that creates a larger roof surface for solar panels, with further solar panels housed in the overhang of the upper deck.
Eco Cruise 50 features 2 electric motors delivering 100 kW each, for a total output of 272 hp. The power to supply the engines comes from a generator (50 kVA) and from solar glass tiles on the roof (4.9 kWp), and it’s stored into a 140 or 240 kWh battery pack.
The cleanest solution replaces the generator with a hydrogen fuel cell, and the normal fuel tank with hydrogen storage tanks. In this case the Eco Cruise 50 is 100% clean, as it can cruise without releasing any polluting emission and in total silence.
Should the customer want more performance even from an electric yacht, Alva offers a Power Version of the Eco Cruise 50, named 50HP, with two 230kW electric motors for a total of 625 hp. In this case the maximum speed can reach 20 knots.
The designers have given the Eco Cruise 50 a peculiar layout, made to maximize space and comfort.
A large beach club area (22 sqm), houses a sunpad but also holds the yacht’s tender and a jet ski. From here, four steps down lead to the lower deck, while a starboard staircase take to the upper one.
The outside areas don’t end in the beach club, but continue upstairs with a raised and protected cockpit featuring a couch and two tables, and with two wide passageways that lead to the foredeck sunpad.
The inner layout of Eco Cruise 50 can be chosen between different versions, with three or four cabins, for private use or for charter. They can be viewed in the renderings, but we underline that one solution sports the master cabin on the upper deck, just behind the pilothouse, with a double bed, a large bathroom, and an office table / vanity corner. The raised position and the glazing on three sides offer a beautiful view on the horizon, quite unique in the 50ft segment.
In any case, the interiors have been developed following a minimalist design and focusing on natural materials and lighting.
With other boat manufacturers entering the electric boat segment, we hope the move to clean cruising will be stronger and stronger, with the leisure navigation sector being, for once, a forerunner and not a pursuer. The signals are promising, and we wait to see some of these projects in the water for real: on their hand, Alva Yachts promise they will have the first units in the water by 2021.
