Lockheed Martin built the Sea SLICE, a 105-foot by 52-foot prototype that showed excellent seakeeping characteristics at high speeds—35 knots—even in Sea State 5 conditions during demonstrations for the U.S. Navy.

EDIT: Pictures too large to post, click link to see.

The Advanced Electric Ship Demonstrator “Sea Jet” undergoes sea trials,
Nov. 30, 2005, on Lake Pend Oreille in Bayview, Idaho.
The 133-foot vessel is testing an underwater discharge water jet called AWJ-21,
a propulsion concept with the goals of providing increased propulsive efficiency,
reduced acoustic signature, and improved maneuverability over previous
destroyer class combatants. U.S. Navy photo by John F. Williams
