NAABSA Not Always Afloat But Safe Aground - most owners will agree only that their vessel (especially deep-sea vessels) proceed only to ports where there is sufficient water to remain always afloat, so as to avoid the risk of hull damage. There are areas and ports, however, where water depth is restricted but, the bottom being soft mud, it is customary for ships to safely lie on the bottom at certain states of the tide - e.g.: River Plate. In such a case, owners will probably agree to proceed NAABSA.

A vessel that is prevented from berthing or from sailing with a full cargo or, indeed, is trapped in a berth by the onset of neap tides, is said to have been "neaped".
