From Aak to Zumbra has the name MENIEPED for a paddled outrigger war canoe used in Micronesia, but by looking to the stamp there is not an outrigger on the canoe, so I am not sure this is the correct name for the canoe depict on the stamp. When only paddled, double ended canoes needed not an outrigger.
The following I found on: http://www.nzetc.org/tm/scholarly/tei-B ... d6-d4.html
It looks more like a double canoe which could carry from 15 to 30 men; the canoe is made of two large logs with a length of thirty till 50 feet, which got hewn out in the form of a canoe.
These two canoes are fastened abreast of each other, with bamboos extended across them.
These canoes are generally about forty feet in length, and the distance between them is from eight to ten feet. The bamboos which unite them are placed about two feet apart and strongly secured to the gunnels by a lashing of their bark cord. Small sticks of bamboo are then extended fore and aft, secured to the cross-pieces, thus forming a light platform from twenty to twenty-five feet in length, and eight or ten feet wide.
They paddle on the two outsides and insides of the canoes (only on the outside of the canoe on the stamp), propelling them forward with astonishing speed.
They are called war-canoes and many of them have very curiously carved heads and sterns, which rise from one to three feet above the hull.
Their paddles are generally four feet in length, with blades about six inches wide, the whole very neatly finished off with carved work, admirably executed.

On November 8, 2012, the Marshall Islands Postal Service issued a new stamp featuring a Traditional Chuuk War Canoe. The canoe is an ancient method of transportation, born when man discovered that he could cross a river or lake atop a floating log. Through experimentation he learned to hollow and shape the log with tools to make it more seaworthy. Soon cultures throughout the world used some form of dugout canoe to traverse large bodies of water. The islanders of Micronesia were once considered to be among the greatest sailors of the Western Pacific. They built outrigger canoes capableof making lengthy journeys and used their knowledge of the ocean, wave patterns and the positions of the stars as their means of navigation. Another canoe known for its ornate stem and stern comes from the Micronesian State of Chuuk. This handsome "war canoe" was lavishly carved and propelled only by paddles
