About this yacht
Light-filled salon and private accommodation
The 2021 Princess Y78 pairs a broad, window-lined interior with a salon fitted with electric Roman blinds. Custom interior soft goods were renewed in 2025, bringing a current finish to the principal living spaces.
Four en-suite staterooms provide the yacht’s guest accommodation, while the owner’s stateroom has a private entrance. Four bathrooms accompany the four-cabin arrangement.
Flybridge and helm arrangement
The flybridge incorporates upgraded helm seats, an electric sun awning, and preparation for a future crane installation. Upgraded seating is also fitted at the lower helm.
A Yacht Controller and Starlink form part of the onboard control and connectivity equipment. Six Lumishore EOS TIX803 underwater lights extend the yacht’s illumination after dark.
