noun
outrigger
OWT-rig-er/ˈaʊtrɪɡər/
A projecting support that stabilizes a boat or vehicle.
The boat's outrigger extends sideways to help keep the hull stable.

Etymology
Outligger meant a spar projecting from a vessel. That outward projection remains central to the modern support: it extends beyond the boat or vehicle to help stabilize it.
In context
The initial step is East Asian ancestry and these people who invented outrigger canoe technology and long-distance sailing.
