The two stamps issued by the Marshall Islands issued in 1993 gives two canoes of the WALAP type used by the people of Enewetak $1 and Jaluit $2 islands.
You could find the WALAP in the waters of the Marshall Islands and Central Pacific; it is the generic term for a sailing canoe. Most often describes an inter-island single outrigger canoe; now extinct.
Hull built up from a dugout keel piece into an asymmetric “V”, the lee side flat and straight the weather side curved fore-and-aft and rounded vertically. Solid end pieces sewn on, terminating in slender raked-up extensions; frequently ornamented with fan shaped pieces. Strong bottom rocker. Five or six closely spaced, light booms connected directly to the stout float; two sturdy booms near the middle of the unit helped support the lee platform. A weather platform built out over the booms; another out of the lee side raked upward; on a very large canoe (wa pap) a small house was set up on each platform. Stout mast stepped in sockets set onto the outrigger close to shrouds to the other ends of the booms. Mast raked forward but pivoted toward the opposite end when tacking, the outrigger always kept to windward. Set a triangular mat sail with apex tacked to the forward end. Sail lashed to yard and boom through holes along one edge. Crew of 3 on smaller canoes, some of the largest could carry 50 passengers.
Reported lengths 5.3 – 21.3 meter; e.g. length 6.7m, beam 0.8m, depth ca 0.9m.
Other recorded names are, “proa volant”, “prao volant”, “wa lab”.
