A '''daggerboard'''  is a retractable [[centreboard]] used by various [[sailing]] craft. While other types of centreboard may pivot to retract, a daggerboard slides in a casing. The shape of the daggerboard converts the forward motion into a windward lift, countering the leeward push of the [[sail]]. The theoretical centre of lateral resistance is on the trailing edge of the daggerboard.{{cn|date=August 2020}}
