Two Birrin fisher-folk ride the wind back to the coast after a
mornings' hunting. Marine creatures surf the waves with them,
hoping for scraps when the catch is gutted and cleaned. The
boat, a small but strong outrigger yacht, was built by the local
tribes to sail relatively close to shore in low tropical seas.
Its frame is built from the tough, plant like stems of local
phototrophic organisms which have been pre-stressed into strong
curved shapes and bound together under a watertight leather
skin. This was then coated with sap and waxes from local plants
and animals to further seal it. Inside the cabin, a birrin can
rest, as well as store the days' catch. If water does flood the
boats' interior, it is not a concern as flotation is provided by
bundles of sponge like plant tissue inside the hull.
