Not quite? An accurate model performs as expected by the developers, producing results in accordance with the desired results of beta-testers (for instance). That does not imply a realistic modelisation, where the model conforms to the dynamics of the represented ship.
E.g. the Ocean Star can be brought to a halt on 1.2 times its own length from 20 kts. Difficult to say it is realistic. It is most probably accurate, because she stops in 2.5 times her length by just letting her go.
