Vessel Walkthrough:

Step aboard Mystic Blue via the hydraulic Tenderlift swim platform, before entering the spacious teak cockpit. Comfortable lounge seating, a beautiful teak table, and premium audio create the perfect setting for relaxing or entertaining outdoors.

Sliding glass doors open into a bright, contemporary salon where panoramic windows, plush seating, and elegant finishes create an inviting atmosphere. Just aft, the fully equipped galley features premium Miele appliances, generous storage, and everything needed for extended cruising.

Forward, the lower helm combines outstanding visibility with Garmin Platinum electronics, FLIR thermal night vision, DockMate wireless joystick control, and intuitive controls for confident navigation in any conditions.

Below deck, the full-beam master suite offers a spacious private retreat with a queen berth, lounge seating, abundant storage, and an en-suite head. The forward VIP stateroom and portside twin guest cabin provide comfortable accommodations for family and guests, while separate crew quarters aft add versatility for extended cruising.

Above, the flybridge is designed for entertaining with multiple seating areas, a wet bar, grill, refrigerator, icemaker, and expansive sun lounges beneath the carbon fiber hardtop. Wide side decks lead to the bow, where cushioned seating and oversized sun pads offer another inviting place to enjoy the views.
