Blue Coast 101 Sailing Catamaran

A unique selling point of this sophisticated concept is its two decks arranged one behind the other, separated by only four steps, and its modern and elegant lines. This innovative concept of double deck configuration with use of the height difference offers a panoramic view for all on board of this unique Super Yacht Catamaran.


This 30.80m sailing catamaran was designed by Jean-Jacques Coste.  Hulls, deck, deckhouse and the entire structure is built from certified "Sealium® Aluminium" and equipped with continuous, highly effective insulation. Safe, strong, reliable and robust!

The flybridge offers the owner and his guests a wonderful outdoor area. A whirlpool, large movable sunbathing areas, a dining table with wet bar and grill leave nothing to be desired. In front the central steering position and the winches for sail guidance.

The main deck has a special layout with two different height levels, separated by 4 steps:

On the lower level, the master suite to port forward, which offers an unrestricted 220° view of the sea and land. Below, a staircase leads to the very spacious bathroom with walk-in wardrobes, double washbasin and large shower.

Next to the master suite, to starboard, is the command centre with the inside steering position.

4 steps up is the saloon deck with a highly elegant design that we can customise to your taste.

To starboard in the saloon a large dining area for 8 guests, a large screen TV and a spacious lounge area to port.

The main deck at the rear of the superstructure offers a huge aft cockpit of almost 90 m2. There you will find a wet bar, a flexible dinner and lounge area, sun loungers for relaxing. On the lower deck, there is an extensive kitchen where the chef serves the guests and a guest toilet.

The hulls house three VIP cabins and the crew area with professional kitchen where the chef serves the guests.

The Blue Coast 101 is easy to sail and allows you to enjoy the luxury and comfort of an innovative yacht. 765 square metres of total sail area provide exceptional performance under sail.

The bow tips can also 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 tilt and therefore does not lose speed.

Instead of traditional diesel engines, the yacht can be equipped with the innovative electric hybrid system "Green ECO Power" with electric motors.

Design according to your preferences

Alternatively, the design of this BLUE COAST 101 can be customised to your requirements in terms of number and layout of cabins, interior fittings and furnishings.
