The assembly further comprises a fin having a mounting post at a base end thereof, the post being at an angle to the lengthwise axis of the fin, and at an angle to a fore-and-aft axis of the fin. The post is disposed in the sleeve and turnable therein to move the fin from a first position in the hull recess wherein the fin is disposed generally axially of the vehicle and conformed to the hull portion, to a second position in which the fin extends outwardly from the hull in a position radial to the vehicle axis and inclined rearwardly at an angle from a line extending radially of the vehicle axis.
