Boat Details

PRIME EIGHT21 is a luxury RIB. I commissioned her build in 2016 and she arrived with me in October that year. Specified to a high level, the team at Ribeye were superb making sure ever detail was perfect. Build photographs included. Storage by Dry Stack since her delivery with the hull cleaned after every lift and drop.


This a powerful yet very high end Rib with wonderful living spaces and seating in both bow and aft areas, she will accommodate multiple guests in motion but also in sunbathing and relaxing with extensive storage compartments. She has been loving cared for, with full Yamaha service history.
