Holland America Line (HAL) said its Nieuw Statendam ship coming in December will have eight more cabins than the Koningsdam introduced last year.
In many other respects the ships are similar, although the Nieuw Statendam will have its own design for public rooms.
Some suites have also been reconfigured to provide more of an open plan, HAL said.
The Nieuw Statendam adds five more oceanview and three more interior staterooms, bringing the total stateroom count to 1,339.
The 32 family oceanview staterooms range from 222 to 231 square feet and have been configured to feature more space to spread out and relax.
HAL said the Nieuw Statendam's Neptune Lounge was enlarged to allow for additional seating and more windows, giving a feeling of openness.
HAL's first ship to be called Statendam sailed in 1898, and this will be the sixth ship in the company's history to carry the name.
