Courtesy of a link at Dark Roasted Blend, I was intrigued to find this video clip of the French CMN Ocean Eagle 43 patrol craft in rough seas. Its trimaran hull is not dissimilar to the Independence class Littoral Combat Ships of the US Navy. Note how smoothly it cuts through the disturbed water.
Mozambique is buying three of these vessels to patrol its coastline. Knowing the waters there from past experience, I'll be interested to see how these patrol boats handle the tropical cyclones ("hurricanes" to US readers) that sometimes sweep down the Mozambique Channel between Africa and Madagascar. The Ocean Eagle's hull design will certainly be tested to its limits in such weather!
