Blue Coast 80 Motor Catamaran

A new "full-custom" performance motor catamaran for world cruising, designed by Jean-Jacques Coste according to Bureau Veritas regulations. At 12m wide, it offers an unusual amount of space for a large family with children and guests, as well as a crew of up to 4.


2 x 4,000 litre fuel tanks and optional auxiliary tanks provide transatlantic range at eco speed.

The large flybridge with hardtop features 4 sun loungers, a dining area with bench seat and chairs, and the outside steering position. In bad weather, the comfortable inside steering position at the front of the saloon is a safe place.

On the main deck there is a large aft cockpit with bench seat and table, and a wet bar with fridge and sink.

On the main deck, in the split-level superstructure forward, is the owner's spacious kingdom in the master suite with large bathroom, desk and lounge sofas with 180-degree views of the sea, bay or marina.

Up 4 steps, the saloon impresses with a dining set for 10, a lounge sofa and the centrally located, elevated interior helm station with panoramic views.

Forward of the superstructure, the forward cockpit offers a bench seat for 10 with tables for cool drinks.

The cabin deck impresses with a VIP cabin with large shower room, a children's cabin and 3 guest cabins, all with en-suite bathrooms. A crew of up to 4 can be accommodated in the two forward crew cabins with en-suite bathrooms.

The galley to port, with direct access to the saloon dining area, is a culinary delight for the owner, guests and children.

The Blue Coast 80 Power can be built from high-tech composite material as well as Sealium® aluminium.

Available with conventional diesel engines or with the innovative electric hybrid system "Green ECO Power".
