A retractable foil mechanism (10) for use in an aquatic vessel is provided comprising: a foil (16, 17) arranged to extend substantially parallel to a first axis (12) when in a retracted position; a rotation axis (36) about which the foil (16, 17) can rotate; means for causing an acting force (F) to act on the foil (16, 17) in a first direction parallel to the first axis (12) so as, in use, to move the foil (16, 17) and the rotation axis (36) in the first direction; and a moment creation arrangement configured such that, in use, the acting force (F) on the foil (16, 17) creates a moment which causes the foil (16, 7) to rotate about the rotation axis (36) while the rotation axis (36) is moving in the first direction.
