2025/2026 Refit
Over the past two years, M/Y I Sea has undergone an extensive full-scale refit of both her interior and exterior, bringing the yacht to an exceptional condition throughout.
A complete repaint of the entire vessel has recently been completed, and just one month ago I Sea departed the shipyard following the completion of major mechanical and technical works. The shafts and propellers were removed, overhauled, balanced, and restored to as-new condition. The stabilizers, bow thruster, anchors, water makers, air-conditioning systems, and all associated machinery have been comprehensively serviced.
Externally, all teak decking throughout the yacht has been completely renewed. I Sea is now equipped with an entirely new selection of water toys and guest amenities, including brand-new SeaBobs, e-foils, an inflatable slide, a swimming pool platform, diving equipment, and numerous additional accessories. The jacuzzi was also replaced with a brand-new unit last year.
The interior has been significantly upgraded to the highest standards. All furniture in both the Owner’s Saloon and Main Saloon has been replaced, including new sofas and dining chairs, while the entire onboard entertainment system has been upgraded. In the Owner’s Master Suite, the mattress, bed linens, carpets, curtains, and soft furnishings have all been renewed. Every guest cabin has received new carpets, linens, towels, and upgraded soft furnishings. All upholstery throughout the yacht has been replaced, every carpet onboard is brand new—with approximately 80% installed within the past 10 days—and new flooring has been fitted in selected areas.
