The interiors of the yacht resonate with a strong Asian colonial feel. Rhoades Young took the inspiration of the interior design from the famous Raffles hotel in Singapore. The interior is adorned with water-colored perspective visuals that enhance the ambiance.

The main focus of the design was to reduce weight to enhance performance. Besides accommodating all the structural and engineering requirements, Rhoades Young developed an interior general arrangement relying on symmetries to establish order and calm. Rhoades Young worked in association with specialist outfitters Oldenburger to develop a method of constructing a rich traditional raised and fielded paneled interior in the lightest materials available. The firm chose wafer thin hardwood veneers over carbon fiber and foam or honeycomb cores
