question - fortified ships

[simwiz2]

When ships are fortified on water do they get the +25% defense bonus? I remember in Civ2 they couldnt be fortified at all, but they could "sleep", so is a fortified ship in civ3 just "sleeping"?

Fortification serves no purpose for ships other than putting them to "sleep" for the time being.
