Sirena
Oceania Sirena is a refined, mid‑size cruise ship offering boutique luxury at sea. Originally launched in 1999 as R4 for Renaissance Cruises before joining Princess in 2002 originally as Tahitian Princess and later Ocean Princess, she joined Oceania Cruises in 2016 following an extensive transformation. Sirena measures 30,277 GT with a 594‑ft length and 9 decks.
Designed for an intimate experience, she accommodates 684 guests and 400 crew. Guests enjoy four open‑seating restaurants, eight lounges and bars, and a stylish pool area with a large heated pool. Significant refurbishments in 2016, 2018, and a 2022 drydock enhanced her suites, dining venues, and outdoor spaces—making Sirena a contemporary yet timeless choice for immersive global itineraries.
