An automatic function from air to water entry occurs by means of a loop (9) on an extension part (10) of the float (1). This loop and extension part separate by reason of their wt. from a hook (12) at the rear end of the float. A guide link (8) hooks into on guide corner (7), and a side plane of the float has a plate (4) narrowing towards the float rear end. |
