The structure of the deck and the Hard Top superstructure were made of carbon fiber, which significantly reduces the weight of the boat and at the same time increases the rigidity of the hull. Designers from Tony Castro were able to install two large skylights in the bow part of the vessel, which additionally allow the water surface to be viewed from the couch. In the very interior of the yacht, at the bow, there is a seating area with a 32-inch TV, which can be easily and quickly transformed into additional accommodation places. In the stern part there is a luxurious sleeping space, while on the starboard side there is a comfortable bathroom fully equipped with a shower and electric toilet. On special request, all rooms can be air-conditioned or heated. The main systems, such as: fuel tanks, pumps, generator or the optional yacht stabilization system, are hidden in the technical room under the aft deck. The 325 GTO can be powered by a pair of outboards rated at 300 to 400hp.
