outrigger

Only one boat was moving, a long canoe with an outrigger; and from this something white was slowly waving.

For a moment the canoe rocked in spite of its steadying outrigger, with the violence of the activities aboard it.

The outrigger acts as a weight on the windward side, to prevent the narrow canoe from being blown over on the opposite side.

This I consider to be a more natural sequence than to suppose the outrigger invented as a means of steadying the dug-out canoe.

Wilkes says that whenever the outrigger gets to the leeward side, there is almost invariably an upset.
