NAABSA (Not Always Afloat But Safely Aground)

"Not always afloat but safely aground", or NAABSA, is used to describe ports where the seabed is suitable for the vessel to rest at low tide without damage to its hull.

What is NAABSA (Not Always Afloat But Safely Aground)?

Not Always Afloat But Safely Aground (NAABSA) is a clause in a charity party (charter agreement) between the shipowner (lessor) and the charterer (lessee), which specify that the chartered vessel may not always be afloat and is allowed to be resting safely aground when falling dry. An NAABSA clause in a charter agreement indicates that the chartered vessel is allowed to be berthed or moored at certain ports where there is a possibility that the vessel rests safely on the port basin.
