Blue Coast 105 Sailing Catamaran

The super yacht catamaran yacht BLUE COAST 105 "Allures" with a timeless elegant design by Jean-Jacques Coste for a sophisticated, fast performance luxury full-custom catamaran.


This BLUE COAST 105 combines luxurious comfort on board with seaworthiness and life at sea with its tremendous performance under sail with 729sqm total sail area and engines of 2 x 440 Ps.

With long waterlines and a very efficient sail plan, the BLUE COAST 105 can reach speeds of over 20 knots in complete safety and comfort. Even under power, the top speed of 16 knots allows fast cruising to the destination.

The large interior volume allows the saloon deck and cabins to be freely arranged according to the owner's wishes.

The flybridge is a very comfortable outdoor area. A whirlpool, large sunbathing areas, a dinner table for 10 people and the wet bar with grill offer plenty of comfort. Forward on both sides a steering position and the winches for sail handling.

On the main deck, in the forward area, a dinner table for 10 people and a lounge area with 180-degree views of the sea, the bay or the marina. In the middle area of the main deck, another very spacious lounge and bar.

To starboard, a luxurious owner's suite with private luxury bathroom with double vanity and whirlpool bath, accessed via stairs.

The spacious aft cockpit is connected to the saloon by a wide-opening sliding door, creating an enormously large open space. Here too, a dinner table for 10 guests and two lounge sofas. The main deck and flybridge are the best places to relax and enjoy with friends and family.

On the lower deck to starboard 2 spacious VIP cabins with en suite facilities and forward crew quarters.  To port is the professional kitchen, where the chef's creativity knows no bounds. In front of it, two more luxurious double cabins and another crew quarter in front.

The interior can be designed according to your style.

The bow tips can be designed as a negative stem to extend the waterline and allow for wave piercing: When waves come from the front, the catamaran is not lifted, it does not lean and therefore does not lose speed.

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


Design according to your preferences

Alternatively, the design of this BLUE COAST 105 can be customised to your requirements in terms of number and layout of cabins, interior fittings and furnishings.
