Built by Boston Boat Works in 2021, CI SEA is a 17.14-metre motor yacht based on the MJM 53z model, the flagship of the MJM line. She combines a refined level of construction quality with a thoughtful layout designed to make the most of her length, offering a genuinely enjoyable experience both underway and at anchor.
One of CI SEA's most notable characteristics is her single-level entertainment space, which connects the pilothouse and aft deck in a seamless, open flow. This layout creates generous room for socialising and relaxing without the separation that multi-level layouts often impose. Below, she accommodates four guests in private comfort across two well-appointed staterooms, delivering a level of privacy and comfort well suited to extended cruising.
CI SEA is a strong choice for owners looking for a capable and well-built motor yacht in the 17-metre range that can serve as a comfortable base for family cruising or time spent with close friends. Her single-level design makes her easy to move around, and her two-cabin layout is ideally suited to couples or small groups seeking a private and comfortable onboard environment.
