No. Cruise ship speed is usually measured in knots - as in 20 knots top speed. To go 20 knots/hour is about like going 22 mph.

The aircraft carriers actually have the capability to extremely fast, speed is over 30 knots. The hydrofoil patrol craft were extremely fast and could go over 48 knots, but the last was decommissioned in 1993. The Asheville class PG's operated on gas turbines and could exceed 42 knots, but I put the last one out of service in 1981. Actual top speeds are classified, these are just what can be found in the public domain.
