I think the implication is supposed to be that Colossal Titans can somehow cross bodies of water or else the threat wouldn't be serious.

I can understand 15 meters and smaller not being able to cross oceans, if a human being with appropriate blades can cut off the nape of a 15 meter and a titan sinks if in water, then clearly a common titan would die from severe water pressure as it would walk along the bottom of the ocean.

Maybe though there is a route from Paradis to the mainland that colossal titans which are way the hell taller could take where they could walk along the bottom of the water and it would not be deep enough around their nape that they would get crushed.

The only other possible alternative explanation is that it's a bluff.
