Sacred units with water cult theme can only go from land to water if both the origin and destination provs have positive dominion.

Water Cult sacred troops get 'poor amphibian' status while they remain in their own dominion. The destination doesn't matter, although your troops will drown if you move into a sea within enemy dominion - because they'll lose their amphibian status on arrival.
