Built by MJM Yachts in 2021, CI SEA is a 16.15-meter motor yacht that offers a balanced combination of comfort, usability and presence on the water. The 53Z represents the flagship of the MJM line, designed with the discriminating buyer in mind and featuring a modern Downeast-inspired profile that works equally well for cruising and entertaining.
CI SEA accommodates four guests across two well-appointed cabins: a full-beam master forward with private ensuite head and shower, and a guest cabin with double berth and dedicated head. The yacht is powered by quad Mercury outboard engines with extended warranties, newly installed alongside updated Garmin navigation electronics. The single-level layout flows seamlessly from the fully enclosed pilothouse—the primary operating and entertainment hub—through to the aft cockpit, both fitted with multiple seating areas, teak tables, and direct access to the swim platform via transom doors. Interior joinery features finely crafted cherry paneling with satin varnish, complemented by gloss teak cabin soles with wenge inlays, removable soft white overhead panels, and custom laid-teak deck covers.
The galley is generously proportioned to port, featuring Corian countertops, a 5.5 cubic-foot Vitrifrigo refrigerator, Isotherm freezer, Wolf induction cooktop, Breville toaster oven, and extensive storage for provisioning. The pilothouse provides full climate control, opening windshields and side windows for flexible ventilation, and panoramic views through multiple portholes and overhead hatches. CI SEA is ideal for owners seeking a capable, well-maintained cruising platform that prioritizes both entertaining space and private accommodations without compromise.
