The stylish interior, designed by Bjorn Johansson, is characterised by simplicity, elegance and light. It is designed to be practical at rest and at sea.

Space and Light

The accommodation of the SIG45 catamaran is remarkably spacious, with generous headroom throughout. The space was achieved through an innovative combination of widening chines on the inboard side of the hulls well above the waterline, and clever use of the available space.

Multifunctional Pilothouses

The pilot houses ensure that the crew can enjoy sailing from below decks as well as on deck, with large windows providing expansive views when seated in the saloon or navigation station. It is a remarkable experience to be comfortably sitting below in a calm and quiet dinette, and to watch the horizon move by at 18 knots.

Gullwing Windows

The huge opening gullwing windows inboard not only provide light and ventilation, but allow food and drinks to be passed easily from the galley to the outside dining areas on deck. When at anchor with both gullwing windows open, the entire deck, saloon and navigation station become a giant connected living space.


The accommodation of the SIG45 catamaran is split between two hulls. This provides privacy unheard of in a 45ft yacht. Crew can be enjoying music and laughter in one hull, while those in the other can be obliviously sleeping, resting or even watching a movie via the sophisticated media system.

Owner’s Hull

The port hull is offered as an owner’s hull, with a large double berth aft, saloon, generous galley and a spacious head with shower.


The starboard hull provides two double cabins, a head with shower and a cosy and practical navigation station / off-watch area. The L-shaped sofa in the navigation station can be used as an extra berth.


Every cabin has at least two openings to ensure good airflow.

Qualilty and Texture

Fittings throughout, including the LED lights, designer Italian taps and textiles are of the highest quality. The interior is constructed using a combination of carbon fibre and wood (composite panels and veneers). Clients may select from finishes on floors, furniture units and fabrics. The floors are made of Oregon Pine, a sustainably harvested wood species that was a mainstay of the boatbuilding industry a century ago.
