Request Pre-Charter InspectionAbout AETERNA
AETERNA is a 53.28-metre full-displacement steel motor yacht built by Radez in 2020 and refitted in 2024. She is registered under the Croatian flag and is a purpose-built charter vessel, with her 499-gross-ton measurement placing her just within a commercially convenient tonnage bracket. Radez is a Croatian yard with experience in larger charter builds tailored to Adriatic operations. Her top speed of 12 knots reflects the full-displacement hull's preference for economy over performance.
AETERNA is configured to carry up to 20 guests across 10 cabins with 12 crew, making her one of the more spacious options in the Adriatic charter market for larger parties. She is well suited to extended family groups, corporate charters, or multi-generational gatherings seeking wide social spaces and high cabin count. Her primary regions are Croatia and Montenegro, with broader Mediterranean access. She is not suited to guests seeking speed, long-range offshore capability, or intimate small-group dynamics; nor does she carry a particularly wide toy inventory relative to her guest count.
Full-displacement steel construction at this length is typical of vessels built for sustained charter use in protected Adriatic waters. The 2024 refit provides confidence in her recent maintenance status. With 10 cabins across a 53-metre platform, each cabin benefits from a reasonable allocation of space, though the overall character prioritises capacity over boutique living.
AETERNA's amenity list is strong for her market: a deck jacuzzi, sun deck, sauna, spa, gym, massage room, outdoor cinema, movie theatre, BBQ, exterior bar, swimming platform, and stabilisers underway. Water toys include two jet-skis, two Seabobs, six paddleboards, an E-foil, electric paddleboard, two kayaks, wake boards, water-skis, snorkelling gear for up to 20, fishing equipment, a floating pool, inflatable platforms, and a banana boat.
The provisional rating is based on available public data, reflecting acceptable standards across safety documentation, maintenance records, and operational protocols. As an independent authority, RightYacht provides owners and charterers with transparent, third-party evaluation — helping inform decisions beyond marketing materials alone.

The actual safety profile may differ significantly.
Provisional scores are calculated from eight factors: vessel age, refit recency, classification society, flag state, crew-to-guest ratio, builder reputation, vessel size, and charter region coverage. All provisional scores are capped at 75/100. Learn how scores work →
