- Wave Powered Boat - A Japanese sailor is planning a solo trip from Hawaii to Japan using the most advanced wave powered boat on the planet. The Suntory Mermaid II turns wave energy into thrust using two fins mounted beneath the bow. They move up and down with the waves to generate ‘kicks’ that propel the boat forward.

Homemade wave-powered boat to cross Atlantic - Gus,a traveler and adventurer, is sharing in his blog the device he will use in his homemade boat to cross the Atlantic. This device uses fins to convert the vertical motion of the waves into horizontal propulsion. Gus thinks he'll be able to achieve speeds of 10 knots or more. (See also is donations page description)
- Wave Propulsion: Brief History and Remedy - French and Russian proponents of harnessing sea wave energy provide a short history, identifying why the approach has been abandoned by major entities, and suggesting how to revive this yet-to-be-fully-actualized approach. (PESN; Sept. 21, 2005)
- Unveiled: The Clean Queen Of The Sea - Orcelle to be the first cargo ship in modern times to be run completely by sun, wind, and waves. Unveiling of first 820-foot long vessel, with cruise speed of 15 knots, expected next month. (Rense / The Telegraph, UK; March 13, 2005)
- Kneider's Wave Energy Propeller Engine - External fin system uses the energy of waves to provide thrust energy for the craft. Benefits the craft by stabilizing the ride. Toy-size proof of concept prototype built. Possible open source project (for experimental purposes only; commercial applications will need to be authorized under contract).

I would think that once you get past a certain speed that the protrusions would inhibit faster flow, rather than help it. This concept might work for initial starting and slow moving, but it would not be practical for a fast-moving vessel. -- Sterling D. Allan (Aug. 7, 2008)
