Request Pre-Charter InspectionAbout BIG ARON
BIG ARON is a 46-metre full-displacement steel motor yacht originally built by Royal Denship in 2004 and refitted in 2020, registered in the Cayman Islands. Her exterior was designed by Ole Steen Knudsen and her interiors by Rune Design, giving her a Scandinavian-influenced character that reflects the Danish shipbuilding tradition of the original yard. At 601 gross tonnes she is one of the heavier vessels at this length, a consequence of steel construction and the full-displacement hull form optimised for long-range passage-making.
BIG ARON is positioned as a long-range charter yacht capable of genuine transatlantic deployment. She accommodates up to 10 guests across five cabins, supported by a crew of 11 — the highest crew-to-guest ratio in this review group, which supports an attentive level of service. Her regions span the full Mediterranean circuit as well as the Caribbean, Bahamas, Cuba, Saint Martin, St Barts, the Virgin Islands, and beyond. She is not suited to guests seeking speed — her maximum of 15 knots is the ceiling for a full-displacement steel vessel of this displacement — nor to those who place significant weight on interior modernity without a full interior refit.
The Royal Denship conversion pedigree and 2020 refit give BIG ARON a workmanlike credibility. Steel displacement vessels of this era and provenance are known for structural robustness and sea-keeping capability in open ocean conditions, where the weight and momentum of a heavy hull provide a predictably stable ride. Her 6,500-nautical-mile range is among the longest in the sub-50-metre category, a genuine operational differentiator for guests planning extended itineraries.
Onboard, BIG ARON offers a deck jacuzzi, sun deck, gym, and accommodation for a varied group. Water sports include two three-seat Waverunners, two wakeboards, three doughnuts, inflatable kayaks, surf boards, water-skis, towable toys for three to four persons, and full scuba diving equipment with snorkelling gear — appropriate for Caribbean and Mediterranean charter days alike. An Argentinean-style BBQ is a distinctive touch reflecting the vessel's character.
The provisional rating is based on available public data, reflecting acceptable standards across safety documentation, maintenance records, and operational protocols.
