Nautica’s main deck has three VIP cabins all with king double beds and ensuites, a lounge area which converts to a fourth cabin if required, plus a large custom built galley and a dining area. The aft main entertaining deck is huge and has full 8m beam. Perfect area for entertaining, dining or just relaxing.
She of course has plenty of dive gear storage, large swim platforms aft with full swim stairs on each hull and davits for the tender.
