About the OCEANIS 51.1 (BENENTEAU)
Shallow draft: 1.85m/6.08'. CE certification A13/B14/C16
The Beneteau Oceanis 51.1, designed by Berret Racoupeau/Nauta Design and built by Beneteau (FRA) in 2016, is a fractional sloop measuring 52.3 ft LOA with a displacement of 30710.0 lb. While the exact hull count is unspecified, the model represents a significant step in Beneteau's performance-oriented cruising line, featuring a 15.75 ft beam and a max draft of 7.55 ft.
- Best for:
- This vessel suits couples or families seeking a spacious, performance-oriented coastal cruiser with modern amenities, as evidenced by the high frequency of comfort upgrades like dodgers, biminis, and solar panels. It is well-suited for those who prioritize ease of handling and modern electronics, given the prevalence of Garmin upgrades and bow thruster installations.
- Bluewater capability:
- With a capsize ratio of 2.02 and a D/L ratio of 126.8, the Oceanis 51.1 offers moderate offshore capability, supported by owner reports of watermaker installations and robust anchor systems like Quick and Delta, though its relatively light displacement suggests it is best suited for protected coastal passages rather than extreme heavy-weather voyaging.
- Comparables:
- Comparable boats include the Beneteau 50 and the Jeanneau 54, as they share similar fractional sloop rigs, beamy hull forms, and target the same market of performance-cruising enthusiasts from the mid-2010s. The Oceanis 51.1 distinguishes itself with a slightly lighter displacement (30710.0 lb) and a more modern interior layout compared to older generation cruisers.
