About the NAJAD 511
HOLDING TANK CAPACITY: 140 L Shallow draft: 6.72'/2.05m Rebranded as part of the Aphrodite series in 2008
The Najad 511 is a robust cruising sloop designed by Judel/Vrolijk and built by Najad, with production records indicating a build year of 2003. As a heavy-displacement vessel with a D/L ratio of 220.12, it is engineered for stability and comfort rather than high-speed performance.
- Best for:
- This boat is ideally suited for serious coastal and offshore cruisers who prioritize seakeeping and comfort over speed, particularly those seeking a stable platform for long passages.
- Bluewater capability:
- With a displacement of 41887.0 lb, a low capsize ratio of 1.7, and a fin keel with a max draft of 7.87 ft, the Najad 511 is well-regarded for offshore passage-making and heavy weather handling.
- Comparables:
- Comparable vessels include the Hallberg-Rassy 43 and the Hallberg-Rassy 46, as they share similar heavy-displacement characteristics, conservative hull forms, and a focus on bluewater cruising integrity.
