These African sailing outriggers use angled planks for amas. The ama generates the needed stability and lateral resistance through dynamic forces occurring from its forward motion through the water. The faster you go, the greater the force generated. "Go fast or swim."
Reminds me of the Orson Wells film of 1942 "Four Men in the Raft"
