A retractable foil mechanism for use in an aquatic vessel is provided comprising: a foil arranged to extend substantially parallel to a first axis when in a retracted position; a rotation axis about which the foil can rotate; means for causing an acting force (F) to act on the foil in a first direction parallel to the first axis so as, in use, to move the foil and the rotation axis in the first direction; and a moment creation arrangement configured such that, in use, the acting force (F) on the foil creates a moment which causes the foil to rotate about the rotation axis while the rotation axis is moving in the first direction.
