Description
CI SEA is a late model 2021 MJM 53z, designed by Doug Zurn and proudly built by Boston Boatworks. The 53z is the Downeast inspired flagship of the MJM line and features expansive single-level entertainment spaces between the pilothouse and aft decks, luxury private accommodations for four, impeccable engineering and construction quality; and truly impressive performance - all key attributes for the discriminating buyer.
The current owners acquired CI SEA in 2022 when almost new, and they have spared absolutely no expense in maintaining and updating this impressive yacht. Recent upgrades include new updated Mercury quad outboards with extended warranties, all new Garmin nav electronics, canvas, fabrics throughout, aft deck teak sole, deck non-skid and much, much more as noted herein. Without a doubt, one will be duly impressed with her condition and extensive features upon inspection.
